Abstract

A large number of received emails can be automatically sorted in a short time.  For this purpose, there is provided a method for sorting emails received by a server having a database that stores therein a search table in which a plurality of tags are associated with their respective one or more keywords and their respective significances.  The method comprises: a receiving step in which the server receives emails from one or more user terminals; an intra-title searching step in which it is determined whether any ones of the same keywords as in the search table are included in the title sections of the emails received by the server in the receiving step; and a sorting step in which the emails received by the server in the receiving step are sorted according to the tags associated with the keywords searched for in the intra-title searching step.  In the intra-title searching step, the server performs the search in an order starting from the keyword(s) of the tag associated with the highest significance, and when any one of the same keywords as in the search table is detected in any one of the title sections, the search of the title section is terminated.

Description

Automatic email content classification method and safety confirmation method

The present invention relates to a received mail content automatic classification method and a safety confirmation method. More specifically, the present invention relates to a method for automatically classifying received mail according to the content and a method for confirming safety at the time of a disaster using the same. It is particularly suitable for safety confirmation using a mobile phone.

Safety confirmation at the time of a disaster includes methods such as confirmation by the presence or absence of a reply by telephone or e-mail using a mobile phone or the like by inputting an ID and password on a web page or the like and confirming by inputting a message (for example, Patent Document 1). reference). In addition, there is a method in which safety confirmation is performed only by replying an email with a keyword written in the body of an email without requiring access to a web page (see, for example, Patent Document 2).

JP 2003-198751 A (0009 paragraph) Japanese Unexamined Patent Publication No. 2007-213768 (paragraph 0006)

However, the method described in Patent Document 1 has a problem that a large number of companies cannot quickly grasp the number of people who can go to work or the number of injured persons. In the method described in Patent Document 1, access to a web page is required for safety confirmation, and there is a concern about server down due to concentration of access. In addition, since multiple replies are required, there are problems that it takes time to confirm safety and that the operation is troublesome.

Also, depending on the job type and attributes, daily IDs and passwords are not used, so there was a problem that the ID and password could not be entered in the event of a disaster and safety confirmation could not be performed. Entering detailed information when there is not enough room is particularly difficult for elderly people who are not familiar with e-mail input operations.

Also, if the information entered on the web page is not examined in detail, the safety information cannot be grasped, and therefore the processing speed is slow relative to the input reception speed, the load on the server is increased, and if there are many people, the processing is enormous. There was a problem that it took time.

In order to classify received e-mails according to the contents, not only at the time of safety confirmation at the time of disaster, it has been necessary to search the whole e-mail text, and it takes time.

Also, when the safety confirmation is performed only by replying to the e-mail, the conventional method is a method in which a fixed character is written in the text as in the method described in Patent Document 2. In this case, when the reply is quoted and the original sentence remains in the text, an incorrect classification that is not the original reply classification may be made. In the recognition of keywords, in order to prevent misrecognition, it was necessary to send a reply with a simple symbol that is not the original keyword. However, when humans visually check this, it is very difficult to understand. There was a weak point. Moreover, since the replyer also needs to convert it to a symbol, there is a weak point that the reply content is easy to be mistaken.

Also, what is described in the text is that the text must be analyzed, and even if the text is only simple text characters, the format of the email varies depending on the model of the terminal such as a mobile phone, and the HTML email or MINE format When complicated analysis such as e-mail is required and a large number of received e-mails must be processed at the time of a disaster etc., processing takes time and a lot of memory.

Also, only the text characters that can be described in the main text can be described, and no further contact was possible.

Also, when the reply e-mail address is fixed, there is a problem that due to this e-mail address being leaked, a large amount of spam mail is received and the normal process is hindered due to the process.

Therefore, an object of the present invention is to provide a method for automatically classifying received mail contents that can automatically classify a large amount of received mails in a short time and a safety confirmation method using the same.

In order to achieve the above object, a first aspect of the present invention includes a database in which a plurality of tags, one or a plurality of keywords for each tag, and a search table in which importance of each tag is associated with each other are stored. A method for a server to classify received emails,
A receiving step in which the server receives mail from one or more user terminals;
For each email received by the server in the receiving step, a subject search step for searching whether the keyword in the search table is included in the subject column of the email; and
The server includes, for each email received in the reception step, a classification step for classifying each email associated with the keyword searched in the subject search step,
In the in-subject search step, the server searches in order from the keyword of the tag associated with the high importance, and when one keyword in the search table is detected in the subject column, Provided is a method for automatically classifying received mail contents, characterized by terminating a search. The search table is preferably a search table having a sub-table A in which a plurality of tags and one or a plurality of keywords for each tag are associated with each other, and a sub-table B in which each tag is associated with an importance level. .

According to the first aspect of the present invention, since the subject field is searched, the processing amount is less than searching the mail text, and the search is completed in a short time. Therefore, quick aggregation is possible. In addition, since the search is performed in descending order of importance, even if a subject is input in free words, it is classified almost accurately while being speedy. In addition, if the first keyword is detected instead of detecting all the keywords, classification is performed based on the keyword, so that processing for each mail is extremely small. Since the number of emails is aggregated by tags, emails of the same type can be instantly aggregated. According to the first aspect of the present invention, a large amount of received emails can be automatically classified in a short time according to the contents even if the subject is described in free words. On the user side, it is simple because it is only necessary to put a short word in the subject line, and it is possible to count even if written in free words, so it is difficult for the total to leak. Also, because the keyword is written in the title, not the text, and the title characters are limited in the number of characters and the description format, the analysis is performed in a much shorter time and with less memory compared to the analysis of the text. Can do. Thereby, for example, even during a large-scale disaster, more mail analysis processing can be performed in a short time. In addition, since the keyword is described in the title, the items to be transmitted can be freely described in the text. It is useful for detailed communication to managers when they do not know what will happen, for example, when confirming safety during a disaster. According to the first aspect of the present invention, the concept of a tag and the concept of importance are introduced for a keyword. Therefore, it is more possible to write a normal word as a keyword and directly write it in a reply. Can provide a user-friendly interface. For example, if there is a keyword “injury”, there are words such as “injury”, “injury”, or “serious injury”, and classify them without error. To help. For example, if “Injury” and “Injury” are made more important than “Injury”, those that were previously described as “Injury” or “Injury” will be omitted before searching for “Injury”. . Therefore, misclassification can be prevented.

further,
The administrator who receives the mail addressed to the aggregation result acquisition request reception mail address from the administrator terminal and determines whether the sender of the received mail is the administrator's mail address registered in the database A confirmation process;
Aggregation process in which the server aggregates the number of emails classified in the classification process for each tag and creates a summary result including a mail number list when it is determined as the administrator's email address in the administrator identification process When,
It is preferable that the server includes a result returning step of returning a mail including the counting result to the transmission source. Alternatively, instead of the administrator identity verification process, the aggregation process, and the result reply process, the server displays a management web screen on the administrator terminal via the network, accepts an input of an aggregation result acquisition request, and acquires the aggregation result When a request is input, the server aggregates the number of mails classified in the classification process for each tag, and creates a totaling result including a mail number list, and after the aggregation process, The server may include a result display step of displaying the aggregation result on the management web screen. In both cases, even if the administrator is at a remote location, the total results can be quickly grasped.

In the database, a distribution destination table in which one or a plurality of groups and one or a plurality of distribution destination email addresses for each group are associated with each other, and each group and a plurality of tags in the search table are associated with each other. A group tag table is also stored,
Before the receiving step,
The server generates a unique identifier for each distribution, generates a mail address including the identifier as a reply mail address, and stores the identifier and the mail address in association with each other in the database. An address setting process;
The server sets the reply destination email address generated in the reply address setting step as a reply destination, sets the delivery destination email address associated with the identifier as a destination, and puts a predetermined keyword in the subject field A mail sending process for sending a delivery mail requesting a reply mail,
The receiving step includes
Upon reception, the server searches whether the identifier stored in the database is included in the destination mail address of the mail, and receives the mail when the identifier stored in the database is included,
Further, it is determined whether the mail source email address matches the delivery destination email address stored in association with the searched identifier,
The in-subject search process searches for the mail determined to match in the receiving process, and it is preferable to search only the tag for the group associated with the matched delivery destination mail address. Since the mail address is different for each delivery, it is possible to know which delivery mail the owner of which delivery destination email address has sent back from the identifier and the sender email address. In addition, since multiple tags selected for each group, that is, different search criteria can be searched, even if there are replies at the same time for many groups, each can be quickly searched with different criteria, and the processing time Less. Since the reply address includes an identifier and is a different address each time, spam mail can be completely eliminated, and no extra load is placed on the server.

In the present invention, “unique” includes the meanings of unique and unique. The “unique identifier” includes, for example, a different identifier each time broadcast is performed. The “identifier” includes a combination of symbols and alphanumeric characters.

The delivery destination table includes a registrant name for each delivery destination email address,
In the result reply step, the server may include a replyer list including a registrant name associated with a delivery destination mail address that matches the transmission source mail address of the received mail for each tag in the count result. preferable. It is possible to notify the administrator of the responder without disclosing the e-mail address of the registrant. If the registrant's e-mail address may be disclosed, each e-mail address may be included in the returnee list. In each case, a replyer list that can identify who responded with each tag, that is, the number of emails with the same type of reply, is also included in the aggregated results, prompting the administrator who replies to which category It can be grasped.

Also, instead of the manager identity verification process, the aggregation process and the result reply process,
In response to a request from the administrator terminal, the server displays a management web screen on the administrator terminal via the network, accepts an input of the aggregation result acquisition request, and receives the input of the aggregation result acquisition request. Is a web counting process for counting the number of emails classified in the classification step for each tag and creating a counting result including a mail number list;
After the counting step, the server includes a result display step for displaying the counting result on the management web screen,
Furthermore, after the result display step,
When the server accepts an input of a reaggregation result acquisition request on the management web screen to the administrator terminal and an input of a reaggregation result acquisition request is made, the server includes an email subject line in the search table. In the body search process for searching for whether the keyword in the search table is included in the body text column of the email for any of the emails for which none of the keywords are searched,
A classification step in which the server classifies each of the tags associated with the keyword searched in the in-text search step for the email in which none of the keywords in the search table is searched in the in-subject search step;
A recounting step in which the server creates a recounting result including a mail number list updated by adding the number of mails with the same tag associated with the keyword searched in the in-text search step to the mail number list; It is preferable to contain. The administrator can be made to input the total result acquisition request to the result display on the web screen. Also, only when the administrator requests re-aggregation, it is only necessary to search the body text field for mail whose contents are unknown in the subject field, so that the processing load on the server to be searched can be reduced. By searching the body text, it is possible to accurately classify more mails. By reflecting the mail searched in the text in the counting result, a more precise counting result can be obtained quickly. It is preferable that after the recounting step, the server includes a recounting result transmitting step of transmitting the recounting result to the manager terminal by e-mail. The administrator can grasp the initial result quickly and then can obtain a more accurate result.

The server displays a management web screen on the administrator terminal via the network in response to a request from the administrator terminal, and a new tag, one or more keywords associated with the tag, and the importance of the tag Preferably, the method includes a tag adding step of adding the received tag, the keyword, and the importance to the search table in association with each other. You can add keywords to search, set tags as classification headings and importance as search priority for the keywords, so customization is easy and optimal recalculation according to the group, situation, etc. Is possible.

Further, it is preferable that the server is a server group including a plurality of servers. By combining servers specialized for functions, it is possible to realize a server group with high processing capacity as a whole, and automatic mail classification can be efficiently performed even if the number of mails to be confirmed is large.

The second aspect of the present invention is a search table in which a plurality of tags, one or a plurality of keywords for each tag, and the importance of each tag are associated with each other;
A delivery destination table in which one or more groups and one or more delivery destination email addresses for each group are associated with each other;
A server comprising a database storing a group-specific tag table in which each group and a plurality of tags in the search table are associated with each other is a method for confirming the safety of the holder of each distribution destination email address. ,
A mail sending step for sending a delivery mail requesting a reply mail with a predetermined keyword in the subject field to each delivery destination email address, with the server as a reply destination for a given reply address for each group;
Next, the receiving step in which the server receives mail addressed to the predetermined reply destination email address;
For each email received in the receiving step, the server searches the email subject column to include keywords in the search table in order from the keyword associated with the highest importance, and in the subject column , A subject search process for ending the search in the subject column when one keyword in the search table is detected;
A classification step in which the server classifies each email received in the reception step for each tag associated with the keyword searched in the in-subject search step;
The administrator who receives the mail addressed to the aggregation result acquisition request reception mail address from the administrator terminal and determines whether the sender of the received mail is the administrator's mail address registered in the database A confirmation process;
Aggregation process in which the server aggregates the number of emails classified in the classification process for each tag and creates a summary result including a mail number list when it is determined as the administrator's email address in the administrator identification process When,
The server includes a result reply step of returning a mail including the mail number list to the transmission source.

According to the second aspect of the present invention, a large amount of received mail can be automatically classified in a short time. Searching the subject field requires less processing than searching the mail text field, and the search is completed in a short time. Therefore, it enables quick counting and is suitable for safety confirmation in an emergency. In addition to just alive confirmation, you can also find detailed information such as whether you are not injured or whether you can join the office by keyword, and for example, the same for keywords of the same type, such as “injury” and “injured” By tagging and counting for each tag, it can be classified by type. In addition, since the search priority is set in the search priority, the search is performed in descending order of importance. Therefore, even when a subject is input in a free word, it is classified quickly and almost accurately. In a disaster, it is difficult to input the words as they are decided, and the input words may be blurred, but even in such a case, quick classification and aggregation can be performed. In addition, if the first keyword is detected instead of detecting all the keywords, classification is performed based on the keyword, and processing for each mail is extremely small. Since the number of emails is aggregated with tags, the number of emails of the same type can be instantly aggregated. Since it can be counted for each group, for example, in a company with a large number of people, it is possible to quickly count how many people can enter the office and how many people have been injured in each department during a disaster. Further, since it is not necessary for the user's communication device to access the web site, the safety can be confirmed even if the user terminal is a communication device having no browser means.

Further, it is preferable that the server is a server group including a plurality of servers. By combining servers specialized for functions, it is possible to realize a server group with high processing capacity as a whole, and automatic mail classification can be efficiently performed even if the number of mails to be confirmed is large.

According to the present invention, a large amount of received mail can be automatically classified in a short time.

The administrator's communication device 60 is, for example, a personal computer (PC), a mobile phone, a PDA, or the like that has a communication means and a browser means by sending and receiving mail. The browser means is a means for browsing a web page by accessing a site on the network, and a means for displaying the web page screen on the screen of the communication device.

The server A: 30 is a server having communication means by mail transmission and mail reception, and the server A: 30 is a keyword search means, classification means, aggregation means, identifier creation means, identifier collation determination means, and mail address collation determination. Means, mail creation means, and reply destination mail address creation means. Server A: 30 automatically receives mail sent to a specific mail address of the server. Server C: 50 is a web server having web display means.

Server B: 40 is a server having a database. The database includes keywords, keyword IDs, tags, tag IDs, importance levels, distribution destination email addresses, user IDs, registrant names, group names, group IDs, managers. Each data of mail address, reply destination mail address, identifier, transmitted mail content, and web form screen is stored and accumulated.

The keyword, keyword ID, tag, tag ID, and importance are included in a search table composed of a plurality of sub-tables and stored in the database. The search table is a table in which a plurality of tags, one or a plurality of keywords for each tag, and the importance of each tag are associated with each other. In the present embodiment, the search table has a sub-table A in which a plurality of tags and one or a plurality of keywords for each tag are associated with each other, and a sub-table B in which each tag is associated with an importance level. Table 1 is an example of sub-table A, and Table 2 is an example of sub-table B. The tag ID is a number for the tag, and the keyword ID is a number for the keyword. There is one tag ID for one keyword, and there are a plurality of keywords for one tag ID. One tag ID has one importance level. Duplicate importance with different tags cannot be set in the same search table. Keywords and tags may be numbers or multilingual.

The delivery destination email address, user ID, registrant name, group name, and group ID are stored in a database included in a delivery destination table composed of a plurality of sub-tables. The delivery destination table is a table in which one or more groups and one or more delivery destination email addresses for each group are associated with each other. In this embodiment, the distribution destination table includes a sub-table A ′ that associates a distribution destination mail address with a user ID corresponding to each distribution destination mail address, and a sub-table B ′ that associates a group ID for each group name with each other. And a sub-table C ′ in which one or a plurality of child group IDs are associated with each other with respect to the parent group ID, and a sub-table D ′ in which the registrant name for the user ID and the group ID of the group to which each user belongs are associated with each other. . Table 3 is an example of the sub-table A ′, Table 4 is an example of the sub-table B ′, Table 5 is an example of the sub-table C ′, and Table 6 is an example of the sub-table D ′. The user ID is a number for the distribution destination mail address, and the group ID is a number for the group name. There is one user ID for one distribution destination email address, and one group ID for one group name. There may be a case where a plurality of groups are included in one group. Moreover, there is one registrant name for a combination of one group ID and one user ID. Group IDs do not overlap each other. User IDs do not overlap each other.

Furthermore, a group-specific tag table in which each group and a plurality of tags in the search table are associated with each other is stored in the database. In this embodiment, the group-specific tag table is a table in which a plurality of tag IDs are associated with each other with respect to a group ID. Table 7 is an example of a tag table for each group. The list of tag IDs in the group-specific tag table serves as a plurality of tag lists used for searching for each group. Since a large unit group including one or a plurality of small unit groups can be set, the convenience is high.

The delivery destination e-mail address may be registered in advance, but it is preferable that each user terminal and the server are registered by performing the identity verification process of the owner of the e-mail address. For example, the identity verification process of the owner of the mail address is performed as follows.

The server receives the request mail addressed to the registration reception mail address, generates a unique identifier consisting of up to 9 alphanumeric characters for each request mail reception, and the identifier and the sender of the request mail Are stored in the database in association with each other, and a confirmation mail is created with the identifier included only in the subject line or in both the subject line and the body, and the reply destination is the confirmation reply mail address. An identifier sending step for sending to the sender's email address, and then the server receives the confirmation reply email addressed to the confirmation reply acceptance email address, and is the same as the identifier stored in the database in the confirmation reply email An email address stored in association with the identifier included in the confirmation reply email is searched for whether the identifier is included. And a received mail analyzing step determines whether to match the sender's email address of the certification reply is registered as the delivery destination mail address when it is determined that the match in the received mail analysis process. Similarly, the administrator e-mail address may be registered in advance, but is preferably registered after confirming the identity.

When grouped, for example, the server receives a request mail addressed to a unique registration reception mail address for each registration destination group, and is a unique identifier for each request mail received, up to 9 alphanumeric characters. And the identifier, the email address of the sender of the request email, and the registration destination group name are stored in the database in association with each other, and the identifier is included only in the subject or in both the subject and the body and is returned. An identifier sending step of creating a confirmation email with the destination as the confirmation reply acceptance email address and sending the confirmation email to the sender email address of the request email; and then, the server addressed to the confirmation reply acceptance email address Receiving a confirmation reply mail and searching whether the confirmation reply mail contains the same identifier as the identifier stored in the database The received mail analysis step for determining whether the email address stored in association with the identifier included in the confirmation reply email matches the email address of the sender of the confirmation reply email, and the received email analysis step When judged, the registered group name associated with the stored mail address is used as a registered group name, and the stored mail address is used as the registrant's mail address, and stored in the database in association with each other. Accordingly, the mail address registration step and the mail address and group name of the delivery destination where the identity of the mail owner is confirmed are registered. The registrant name may be entered in the confirmation reply mail text, and the text may be registered as the registrant name.

The reply mail address may be a fixed mail address unique to each group, but is preferably a unique mail address including an identifier for each distribution. This will be described in detail later.

The identifier is a different e-mail address each time it is issued. This email address is disposable each time and does not allow duplication in the past or future. The identifier is created by a combination of symbols and alphanumeric characters by identifier creating means.

The content of the sent mail includes the mail content of the delivery mail. The mail content of the distribution mail is a content for requesting a reply mail in which a predetermined keyword is entered in the subject field.

The web form screen includes a screen for accepting an input of an ID and a password to the administrator, a screen for accepting an input of an aggregation result acquisition request or a reaggregation result acquisition request, a screen indicating the aggregation result, a new tag and one associated with the tag A screen for receiving input of a plurality of keywords and the importance of the tag and a delivery mail text selection screen are included.

Server A: 30 is equipped with a received mail content automatic classification program, an aggregation program, a mail address type determination program, a mail address owner confirmation program, and a mail delivery program.

The received mail content automatic classification program has a function of searching a computer for a keyword in a subject line of a mail, a function of searching for a tag stored in association with the searched keyword, and a function of classifying a received mail for each tag. In order to realize a function for storing received mail contents in a database, a function for searching for a keyword in a mail text field, a function for receiving mail, a function for creating an identifier, and a function for storing a mail address and an identifier in association with each other It is a program.

Server A: 30, Server B: 40, and Server C: 50 are each a hardware control device comprising a CPU, memory, operating system, device driver, etc., secondary storage such as a magnetic disk, LAN board, etc. Etc. are provided. Server C: 50 is an ordinary web server that sends the HTML file that composes the web screen to the terminal that requested the web screen acquisition, displays it on the screen of the communication device, and receives the input data on the web screen It has a device to do. Server A: 30, server B: 40, and server C: 50 are connected to each other via a LAN, the Internet, or the like, and the received mail content automatic classification processing of the present invention based on an operation command from server A: 30, accompanying this Aggregation processing, email address type determination processing, email address owner identification processing, and email delivery processing.

On the magnetic disk of server A: 30, a received mail content automatic classification program, an aggregation program, a mail address type determination program, a mail address owner confirmation program, and a mail delivery program are stored. The above-described database is stored on the magnetic disk of server C: 50. The server A: 30, the server B: 40, and the server C: 50 function as mail transmission / reception servers, database servers, and web servers, respectively. Each server has a clock function or the like that a normal server has.

Server A: 30, Server B: 40, Server C: 50 are the server A: 30 CPU, server A: 30 received mail content automatic classification program, aggregation program, mail address type determination program, and mail address owner confirmation By loading the program and the mail delivery program into the memory of the server A: 30 and executing them, the received mail content automatic classification process of the present invention, the accompanying aggregation process, the mail address type determination process, the mail address owner identity verification A computer function capable of processing and mail delivery processing is realized. The CPU of each server is an arithmetic processing device mounted on a normal computer, and can execute various programs and perform various controls.

The server A: 30 has first communication means for transmitting and receiving data with the communication device 10 by mail, and server B: 40 has second communication means for transmitting and receiving data and the like. The server B: 40 has first communication means for transmitting / receiving data etc. to / from the server A: 30, and second communication means for transmitting / receiving data etc. to / from the server C: 50. The user terminal has communication means for transmitting / receiving data to / from the server A: 30 by mail. The administrator terminal includes a first communication unit that transmits and receives data with the server A: 30 by mail, and a second communication unit that transmits and receives data on the web screen via the server C: 50 and the Internet.

The keyword search means accesses the server B: 40, matches the character data included in the subject field of the mail received by the server A: 30 with the keyword stored in the database of the server B: 40, and matches Judge whether to do. The keyword to be searched is only the keyword stored in association with the predetermined tag, and the search order is performed in the order of importance associated with the tag. In the present embodiment, the search is performed in order from the keyword with respect to the tag associated with the importance having a large numerical value. If even one keyword is detected, the search is terminated. In the case of each group, the predetermined tag is a tag group corresponding to a tag ID group stored in association with the group specified by the destination mail address of the received mail. When the tags to be used are all tags in the search table, the keyword is searched based on the search table regardless of the group-specific tag table.

In the present embodiment, the keyword search means also includes the character data included in the text of the mail for the received mail classified by the classification means in response to a request from the administrator terminal. Search in the same way as the search for character data.

The classification means accesses the server B: 40 based on the search result by the keyword search means, classifies the received mail for each tag, and stores it in the database. In this embodiment, if no keyword is detected, it is classified into the other and stored in the database.

The counting means totals the number of received mails classified for each tag and stored in the database for each tag. Create a mail count list from the totaled results and store it in the database. Create a tabulation result including the mail count list and store it in the database. In addition to the mail number list, it may include the number of destination mail addresses, the number of delivery errors, and the like. In response to a request from the administrator terminal, a returner list including a registrant name associated with a distribution destination mail address that matches the transmission source mail address of the received mail for each tag is also included in the count result.

The identifier creating means creates an identifier based on the system time using the clock function of the server A: 30. For example, it is created by a combination of symbols and alphanumeric characters such as “{LAwg6nT}” and “0627su1i2xqu”. Alphanumeric characters include upper and lower case alphabets and mathematical numbers. By combining date data and a unique key generated based on the system time of the server A: 30, it is automatically created so as not to overlap with other identifiers stored in the database of the server B: 40. In this embodiment, the identifier is included in a part of the reply destination email address of the email created by the reply destination email address creating means.

The identifier collation determination means accesses the server B: 40, and checks the character data included in the destination mail address of the mail received by the server A: 30 with all the identifiers stored in the database of the server B: 30. And determine whether they match.

The e-mail address verification determination means accesses the server B: 40, and checks whether the e-mail address of the e-mail received by the server A: 30 matches the e-mail address stored in association with the specific identifier. Determine. Here, the specific identifier refers to an identifier determined to be matched by the identifier collation determination unit. In the case of mail addressed to the distribution request reception mail address and mail addressed to the aggregation result acquisition request reception mail address, it is determined whether or not the transmission source mail address matches the administrator mail address stored in the database.

The reply mail address creating means creates an mail address by combining the identifier created by the identifier creating means with predetermined character data. For example, in the email address for accepting safety confirmation email replies, the domain is “aaa.aa.jp”, “-ans” is added at the end of the email account, and a reply email address is created. If the created identifier is “0627su1i2xqu”, an email address “0627su1i2xqu-groupa-ans@aaa.aa.jp” is automatically created by combining these identifiers. For example, the character string to be added at the end of the mail account is created as “-ans” for the safety confirmation mail reply receiving mail address and “-cnt” for the counting result acquisition request mail address.

If you do not include an identifier in the reply-to email address, it can be a fixed email address, for example, a fixed email address for each group whose email account string is “English by group- ans”, but it is fixed The character string of the mail address is not limited to these.

Server A: 30 can have multiple email accounts. In addition to having a mailbox for a fixed mail address, a temporary mailbox is also generated for the mail address generated by the reply destination mail address creating means.

Depending on the purpose, the mail creation means sets the destination as the delivery destination mail address stored in the database, the sender mail address of the received mail, or the administrator mail address stored in the database, and the reply destination according to the purpose. Create an email as a specific email address. Depending on the purpose, the reply destination is the mail address created by the reply destination mail address creating means.

The web display means is a means for providing a web page that can be accessed through the network. In response to an access from the communication device, an HTML file as an administrator web screen is transmitted to the communication device and displayed on the screen of the communication device. This is a means for transmitting the data inputted in the form in the administrator web screen to the server. The web display means accesses the server B: 40, retrieves web form screen data including a mail address entry field, and provides it on the network. For example, the administrator web screen is displayed via the network on the screen of the user's terminal that has accessed the web page including the administrator web screen data. In this embodiment, the administrator web screen includes an ID, a password, and a tabulation result acquisition request input screen, a tabulation result display screen, a tabulation result acquisition request input screen, a new tag, A screen for accepting input of one or more keywords to be associated with the tag and the importance of the tag is included. The input is received on the input receiving screen, and the input data is transmitted to the server A: 30.

The address type determination means accesses the server B: 40 and determines whether the destination of the mail received by the server A: 30 is a safety confirmation mail reply reception mail address, a count result acquisition request reception mail address, or a registration reception mail address. Whether it is a confirmation reply reception mail address or a distribution request reception mail address is determined.

In this embodiment, the server A: 30 is configured to use the above-described hardware configuration and mail address owner identification program to search for keyword search means, classification means, counting means, identifier creation means, identifier collation determination means, and mail address collation determination means. It functions as a mail creation means and a reply mail address creation means.

Server C: 50 functions as a web display means by the hardware configuration described above. Further, the server B: 40 functions as a data storage / accumulation unit in accordance with an instruction from the server A: 30 with the above-described hardware configuration.

{procedure}
The received mail content automatic classification method of this embodiment is also an embodiment of a safety confirmation method, a search table in which a plurality of tags, one or a plurality of keywords for each tag, and the importance of each tag are associated with each other; A distribution destination table in which one or a plurality of groups and one or a plurality of distribution destination email addresses for each group are associated with each other, and a group-specific tag table in which each of the groups and a plurality of tags in the search table are associated with each other Is a method for confirming the safety of the owner of each distribution destination mail address, wherein the server receives the distribution request mail from the administrator terminal, and the person of the transmission source mail address A delivery mail creation step of confirming and creating a delivery mail when confirmation is made, the server returns a predetermined reply for each group A mail sending step of sending a delivery mail requesting a reply mail with a mail address as a reply destination and a predetermined keyword in the subject field to each delivery destination mail address, and then the server sends the predetermined reply destination A receiving step for receiving a mail addressed to a mail address, and for each mail received by the server in the receiving step, whether or not a keyword in the search table is included in a mail subject field is associated with a high importance level. The search is performed in order from the keyword, and the search in the subject is terminated when one keyword in the search table is detected in the subject column, and the server receives the search in the reception step. A classifying step for classifying each received email by tag associated with the keyword searched in the subject search step; Receiving the mail addressed to the aggregation result acquisition request receiving mail address from the administrator terminal, and determining whether the received mail source is the administrator's mail address registered in the database; When it is determined as the administrator's email address in the administrator identity verification step, the server counts the number of emails classified in the classification step for each tag, and creates a count result including a mail number list; A safety confirmation method including a result reply step in which the server returns a mail including the mail number list to the transmission source.

In this embodiment, instead of the administrator identity verification process, the aggregation process, and the result reply process by sending and receiving mail, a management web screen is displayed on the administrator terminal via the network in response to a request from the administrator terminal. When the input of the acquisition result acquisition request is received and the input of the acquisition result acquisition request is received, the server adds up the number of mails classified in the classification step for each tag, and creates a total result including the mail number list. And a result display step in which the server displays the totaled result on the management web screen after the totaling step. Further, after the result display step, when the server accepts an input of a recalculation result acquisition request on the management web screen to the administrator terminal and the reaggregation result acquisition request is input, the server displays the subject field of the mail. In addition, for an email for which none of the keywords in the search table has been searched, an in-text search step for searching whether the keyword in the search table is included in the body text column of the email, and the server includes a keyword in the search table A mail that has not been searched for, a classification step that classifies each email associated with the keyword searched in the in-text search step, and a tag that the server associates with the keyword searched in the in-text search step A recounter that creates a recount result that includes the updated mail number list by adding the same number of mails to the mail number list Including the door. Further, the server displays a management web screen on the administrator terminal via the network in response to a request from the administrator terminal, and the new tag, one or more keywords associated with the tag, and the importance of the tag are displayed. A tag adding step of receiving an input and adding the received tag, keyword, and importance to the search table in association with each other is included. Furthermore, in the search table to which tags have been added in the tag addition process, the search process within the subject and the classification process are performed again, and the number of reclassified mails is counted for each tag, and a count result including a mail number list is created. Then, the tabulation result may be displayed on the management web screen. Note that the contents of the classified received mail may be displayed on the management web screen, and manually reclassified according to the contents, and may be totaled again.

FIG. 2 is a flowchart showing main processes in the server in the embodiment 1 of the received mail content automatic classification method of the present invention. The received mail content automatic classification program causes a computer to execute the following steps. Note that the administrator e-mail address that is the distribution source of the simultaneous e-mail is stored in the database in the server B: 40. In this embodiment, the administrator email address is registered in advance by confirming the identity of the owner of the email address described above.

(Step 101)
When a mail is transmitted to the server A: 30, a mail address type determination program is activated, and the address type determination means determines whether the destination mail address of the transmitted mail is a specific mail address of the server. A mail box corresponding to a specific mail address exists in the server, and when a mail arrives at the mail box, each processing program is started. Upon reception, the server A: 30 searches for the identifier stored in the database in the destination mail address of the transmitted mail, and when the identifier not stored in the database is included, the mail address itself exists. Do not receive because it does not. When the identifier stored in the database is included, or when the identifier itself is not included, the process proceeds. If it is a safety confirmation mail reply reception mail address (~ "-ans" @ ~ in FIG. 2), the received mail content automatic classification program is started and the process proceeds to step 201. When the counting result acquisition request reception e-mail address is (-"-cnt" @ ~ in Fig. 2), the program that executes steps 301 to 302 of the e-mail address owner identification program is started and the aggregation program is executed after the identification is confirmed. Starts. First, the process proceeds to step 301. In this embodiment, step 102 is always performed in parallel with step 101, and a wait is made for whether an e-mail is transmitted or an input is made from the web form screen.

In addition, in the case of a distribution request reception e-mail address or a registration reception e-mail address, the e-mail address owner identification program is activated and the above-described identification process is executed to cause the e-mail sender to reply to the confirmation reply reception e-mail address. In the case of a confirmation reply acceptance mail address, the mail address owner identity confirmation program is activated, the identity confirmation process described above is executed, and identity confirmation is performed by the returned email. If the confirmed email address is the email address received at the delivery request acceptance email address, after confirming the identity, the email delivery program is activated to create a delivery email and deliver it to the user terminal. If the confirmed email address is the email address accepted at the registration acceptance email address, the email address etc. is registered by the email address owner identity verification program. When the mail address is neither the reception mail address nor the confirmation reply mail address, the mail is not received. The administrator's communication device: 60 is notified of the aggregation result acquisition request reception mail address and the distribution request reception mail address. In this embodiment, the received e-mail address has a format of “group name—command by process @ ˜”. For example, “groupa-add@xx.co.jp”. The reception e-mail address is preferably created by including a unique identifier for each distribution, that is, a different identifier each time. In parallel with step 101, step 102 is also performed at all times, waiting for whether an e-mail is sent or there is an input from the web form screen.

Next, the processing after a broadcast mail is sent from the administrator terminal will be explained. This broadcast mail starts the mail distribution program after the identity is confirmed in response to a request from the administrator terminal. Created and sent as follows: The server A: 30 generates a unique identifier every time it is distributed by the identifier creating unit, and creates a mail address including the created identifier by the reply destination mail address creating unit. For example, if the created identifier is “0627su1i2xqu”, it is preferable to set a different mail address each time, such as “0627su1i2xqu-groupa-ans@aaa.aa.jp”. When the identifier is assigned, the identifier is associated with the delivery destination mail address and stored in the database of the server B: 40. Use the mail creation means as the reply mail address created as the reply destination, for example, send mail content, for example, “A disaster has occurred, is it safe? Write one of the following in the subject line and reply. As described above, an e-mail having a content requesting a reply e-mail with a predetermined keyword in the subject field is created. The text is not limited to this. For example, “Please let us know if you have attendance. Please reply with one of the following in the subject line. The content of the transmitted mail may be content described in the body of the request mail from the administrator, or may be transmitted mail content data registered in advance. On the web screen, the administrator may select or input the contents of the outgoing mail. In order to avoid misclassification, the subject is preferably a subject that is classified as other when it is sent back with "Re:" appended to the sent subject. In the present embodiment, the subject is “safety confirmation”, but is not limited thereto. The destination is the delivery mail address of each group. After creating such delivery mail, it is delivered simultaneously by communication means. If you do not need to know which delivery email you are replying to and you do not need high security, you can use a fixed email address, but you can use a different safety confirmation email reply acceptance email address for each group. There must be. When there is only one group as a whole, it is not necessary to enter a character string for identifying the group. The reply destination mail address is stored in the database of the server B: 40 in association with each group ID in the distribution destination table. Since the user who received the distribution mail can enter the reply subject by looking at the keyword in the text, it is highly convenient. The user selects only one keyword from a plurality of keywords described in the delivery mail, fills in the subject line field, and sends a reply.

(Step 102)
The server C: 50 accepts the web screen for the administrator of the web site provided by the server on the network by the web display means. In this case, the server provides a web page accessible through the network. The web screen for accepting input of ID, password, and total acquisition request is displayed on the screen of the communication device that can display the web screen that has accessed the web page, and accepts the input. The communication device displaying the web screen transmits the input data input on the web screen to the server when the transmission button is clicked by the user. When the server C: 50 displays a management web screen on the administrator terminal via the network in response to a request from the administrator terminal, accepts an input of an aggregation result acquisition request, and receives an input of the aggregation result acquisition request, The server A: 30 performs a web totaling process for totalizing the number of mails classified in the classification process for each tag and creating a totaling result including a mail number list. First, the server receives the transmitted input data, determines whether or not the ID and password of the administrator registered in advance match the ID and password of the administrator by a general method, and if they match, the total result from the administrator Recognizing that the request is an acquisition request, the counting program is activated and proceeds to step 313.

(Step 201)
Server A: 30 receives a mail (reply mail) addressed to a safety confirmation mail reply reception mail address (~ "-ans" @ ~ in FIG. 2). The server A: 30 determines whether or not the received mail is normal. If there is an abnormality, the server A: 30 discards the mail and ends the process. Mail with “abnormal” includes mail that is suspected of being virus mail or spam mail, for example, mail having a larger file size than necessary or mail including an attached file.

(Step 202)
The server A: 30 receives each of the character strings before “-ans” in the safety confirmation mail reply reception mail address and receives them in different mailboxes and processes them. It is determined whether the source mail address of the received mail matches the distribution destination mail address included in the distribution destination table stored in association with the identifier included in the destination mail address of the received mail. When there is no identifier and when the result of determination is coincident, the process proceeds to step 203. If they do not match, the mail is discarded and the process is terminated. When the identifier is included, it is possible not only to know which delivery destination group the received mail is a reply to, but also to identify which delivery mail the reply is for.

(Step 203)
The server A: 30 performs a search process within the subject for searching for whether the keyword in the search table is included in the subject column of the mail. The server A: 30 accesses the database of the server B: 40 by keyword search means, searches the group ID stored in association with the destination mail address of the received mail, and associates it with the group ID. For all the tag IDs stored, the keywords stored in association in the search table are sorted in the descending order of importance stored in association with each tag ID, and the presence or absence of keywords from the highest importance order. Search for. For example, if the destination mail address of the received mail is stored in association with the group whose group ID is 100 in Table 7, the tag IDs are 1 and 2, so the keyword in the applied search table is “safe” “Injury”, “Injury”, “Injury”. First, a search is made as to whether “safe” and “injury” are included in the subject line. If not found, “injury” and “injury” are searched. As a result, it is possible to prevent “injury” from being classified even though “injury is absent”. In addition, even if a phrase to be entered in the subject field is displayed as an option in the delivery mail, the option number or a free expression word may be written in the subject field and returned. In the present embodiment, a plurality of keywords can be registered for one tag. Therefore, even if a synonym or option number is input, it can be prevented from being misclassified.

The server A: 30 ends the search in the subject field when one keyword in the applied search table is detected in the subject field. Next, the routine proceeds to step 204. The server searches in order from the keyword of the tag associated with the higher importance, and when one keyword in the search table is detected in the subject field, the search in the subject field is terminated. Very little processing and time is required. In addition, despite the high speed, it enables accurate classification even if it is not a reply with an accurate word.

Also, since the keywords in the text are not targeted for analysis, even if the reply message received by the responder is a distribution mail describing the keywords, it will not be misclassified.

(Step 204)
The server A: 30 performs a classification process for classifying each tag associated with the keyword searched in the in-subject search process. The received mail is classified and stored for each tag in the database of the server B: 40 while retaining information such as the transmission source, subject, and text by the classification means. Emails for which no keywords were found are classified as other. After classification, the process ends.

(Step 301)
The server A: 30 receives an email addressed to the aggregation result acquisition request reception email address from the administrator terminal, and determines whether the sender of the received email is the email address of the administrator registered in the database Perform the identity verification process. First, the server A: 30 receives a mail (request mail) addressed to an aggregation result acquisition request reception mail address (˜ “-cnt” @ ˜ in FIG. 2). The server A: 30 determines whether or not there is an abnormality in the received mail. If there is an abnormality, the mail is discarded and the process is terminated. Mail with “abnormal” includes mail that is suspected of being virus mail or spam mail, for example, mail having a larger file size than necessary or mail including an attached file.

(Step 302)
Server A: 30 compares the source mail address of the received mail with the administrator mail address stored in the database to determine whether they match. If they do not match, the mail is discarded and the process is terminated. If they match, it is recognized that the received mail is from the administrator, the counting program is started, and the process proceeds to step 303.

(Step 303)
The server A: 30 performs a counting process of counting the number of mails classified in the classification process for each tag and creating a counting result including a mail number list. First, the number of received mails classified and stored for each tag is totaled for each tag by the counting means, and a mail number list is created. The mail number list is, for example, a list such as “Safe 100, Injury 10”. For each group, all received emails received and classified before the counting process are included in the total number. When an identifier is included in the reply destination of the distribution mail, it is possible to grasp which distribution mail is counted for the reply mail. The total number of delivered emails, the number of emails that have been replied, and the number of emails for each tag are quickly tabulated, and a tabulation result including a mail count list is created. Proceed to step 304.

(Step 304)
The server A: 30 performs a result return step of returning a mail including the counting result to the transmission source. An email including the created aggregation result is created by the email creation means, and the communication means returns to the administrator email address that is the sender of the email sent to the email reception address for the collection result acquisition request, and the processing ends. . Since the classification is already done, the administrator can immediately obtain a real-time count result every time a count result acquisition request is made by e-mail. In addition to the mail number list, a returner list including a registrant name associated with a distribution destination mail address that matches the transmission source mail address of the received mail for each tag may be included in the count result. Administrators can quickly figure out who received what type of reply.

(Step 313)
The server A: 30 counts the number of received mails classified and stored for each tag by the counting means, and creates a mail number list. For each group, all received emails received and classified before the counting process are included in the total number. When an identifier is included in the reply destination of the distribution mail, it is possible to grasp which distribution mail is counted for the reply mail. The total number of delivered emails, the number of emails that have been replied, and the number of emails for each tag are quickly tabulated, and a tabulation result including a mail count list is created. Next, the process proceeds to step 314.

(Step 314)
The server C: 50 performs a result display step of displaying the aggregation result on the management web screen by the web display means. Since the classification has already been performed, the administrator can immediately obtain a real-time count result every time a count result acquisition request is made on the web site. In addition to the mail number list, a returner list including a registrant name associated with a distribution destination mail address that matches the transmission source mail address of the received mail for each tag may be included in the count result. Administrators can quickly figure out who received what type of reply. Next, the process proceeds to step 315.

(Step 315)
Server C: 50, on the management web screen, a totaling result acquisition request for summing up the subject field again, a reaggregating result acquisition request for summing up the search in the text field, a tag addition request, and a received mail content display , Accepts the end input. When a totaling result acquisition request is input, the process returns to step 313. When a reaggregating result acquisition request is input, the process proceeds to step 316. When a tag addition request is input, the process proceeds to step 320. When the received mail content display is input, the process proceeds to step 330. When the end is input, the process ends.

(Step 316)
When the re-aggregation result acquisition request is input, the server A: 30 sends an email in which no keyword in the search table has been searched in the email subject column to the email text column in the search table. An in-text search step is performed to search for whether a keyword is included. When there are many other classified results obtained in step 314 and the user wants to collect the results again with reference to the main text, the administrator displays the management results displayed on the screen of the administrator's communication device by the web display means. On the web screen, the user can select a recalculation result acquisition request button and select keyword search in the text as well as in the subject. When the re-aggregation result acquisition request is input from the administrator terminal, the server A: 30 subjects the received mail classified as “others” stored in the server B: 40 to the above-described subject by the keyword search means. The keyword search is performed in the text column in the same manner as the internal search process. When one keyword is searched, the search is terminated. When one keyword in the applied search table is detected in the text column, the search in the text column is terminated. Next, the process proceeds to step 317. You can also correctly classify emails that have been incorrectly entered in the body of the reply.

(Step 317)
The server A: 30 performs a classification process for classifying, for each tag associated with the keyword searched in the in-text search process, an email in which none of the keywords in the search table has been searched in the search process within the subject of step 203 Do. Regarding the mail classified as other in step 204 by the server A: 30, the server B: 40 retains information such as the transmission source, the subject, and the text by the classification means based on the search result in the text search process. Are classified and stored for each tag in the database. Emails for which no keywords were found are classified as other. After classification, the process ends. As a result, among the received mails classified as other, mails whose keywords are found in the body are sorted into correct classifications. Next, the process proceeds to step 318.

(Step 318)
A re-aggregation step in which the server A: 30 creates a re-aggregation result including an updated mail number list by adding the number of mails having the same tag associated with the keyword searched in the in-text search step to the mail number list I do. The server A: 30 counts the number of received mails classified and stored for each tag by the counting means, and creates a mail number list. This mail number list also reflects the search results in the text. For each group, all received emails received and classified before the counting process are included in the total number. When an identifier is included in the reply destination of the distribution mail, it is possible to grasp which distribution mail is counted for the reply mail. Next, the process proceeds to step 319.

(Step 319)
The server C: 50 performs a result display step of displaying the aggregation result on the management web screen by the web display means. Although reclassification takes time, the administrator can obtain a more accurate count result on the web site. In addition to the mail number list, a returner list including a registrant name associated with a distribution destination mail address that matches the transmission source mail address of the received mail for each tag may be included in the count result. The administrator can understand who received what kind of reply. Then, the process returns to step 315.

(Step 320)
Server C: 50 displays a management web screen, accepts input of a new tag, one or more keywords associated with the tag, and the importance of the tag, and server C: 50 inputs to server A: 30 Then, the server A: 30 performs a tag addition step of associating the transmitted tag, keyword, and importance with each other and adding it to the search table. For example, in the case of tables such as Table 1, Table 2, and Table 7, the server A: 30 adds the input tag to the sub-table B shown in Table 2 along with its importance. The keyword that is automatically issued and entered so that the tag ID does not overlap with other tag IDs is added to the sub-table A shown in Table 1 together with the tag ID. The keyword ID is automatically issued so that it does not overlap with other keyword IDs. The tag ID of the added tag is added to the corresponding group ID in the group-specific tag table shown in Table 7. Then, the process returns to step 315. In the next and subsequent searches, a search reflecting the newly added tag can be performed. Convenience is high because the administrator can freely change the classification settings.

(Step 330)
Server C: 50 displays a management web screen and accepts an input for selecting a mail whose contents are to be displayed from a list of received mail classified as other. When the input is made, server C: 50 : The corresponding received mail among the received mails stored in 40 is displayed. The administrator reads the contents of the email and manually reclassifies it into the appropriate classification. For example, the received mail mark to be reclassified into the tag BOX for each tag on the screen is reclassified by a method such as dragging and moving. Then, the process returns to step 315. The list of received mails may be displayed in the subject field. Emails with reply contents in the subject can be reclassified simply by displaying the subject, so they can be quickly reclassified.

{effect}
According to the present embodiment, a large amount of received mail can be automatically classified in a short time. Since the subject field is searched, the processing amount is less than searching the mail body, and the search is completed in a short time. Therefore, quick aggregation is possible. In addition, since the search is performed in descending order of importance, even if a subject is input in free words, it is classified almost accurately while being speedy. In addition, if the first keyword is detected instead of detecting all the keywords, classification is performed based on the keyword, so that processing for each mail is extremely small. Since the number of emails is aggregated by tags, emails of the same type can be instantly aggregated. Classification is possible even if the subject line is written in free words.

The user can simply put a short word in the subject field, so it is convenient and can be counted even if it is written in free words. Also, because the keyword is written in the title, not the text, and the title characters are limited in the number of characters and the description format, the analysis is performed in a much shorter time and with less memory compared to the analysis of the text. Can do. Thereby, for example, even during a large-scale disaster, more mail analysis processing can be performed in a short time. In addition, since the keyword is described in the title, the items to be transmitted can be freely described in the text. It is useful for detailed communication to managers when they do not know what will happen, for example, when confirming safety during a disaster. According to the first aspect of the present invention, the concept of a tag and the concept of importance are introduced for a keyword. Therefore, it is more possible to write a normal word as a keyword and directly write it in a reply. Can provide a user-friendly interface. In this embodiment, there is a keyword “injury” in this example, but there are not only “injury” but also words such as “injury” and “injury”. Help to classify. If “injury” is made more important than “injury”, those that have previously been described as “injury” are omitted before “injury” is searched. Therefore, misclassification can be prevented.

According to the present embodiment, since the administrator can acquire the aggregation result on the email or web screen, the administrator can quickly grasp the aggregation result even if the administrator is in a remote place.

According to the present embodiment, since the mail address is different for each distribution, it can be understood from the identifier and the transmission source mail address that the owner of which distribution destination mail address has returned about which distribution mail. In addition, since multiple tags selected for each group, that is, different search criteria can be searched, even if there are replies at the same time for many groups, each can be quickly searched with different criteria, and the processing time Less. Since the reply address includes an identifier and is a different address each time, spam mail can be completely eliminated, and no extra load is placed on the server.

According to the present embodiment, it is possible to notify the administrator of the responder without disclosing the registrant's email address. A list of respondents who can identify who sent a reply along with the number of emails with the same type of content for each tag, which is also included in the aggregated results, allows the administrator to quickly grasp who belongs to which category Can do.

According to the present embodiment, it is possible to allow the administrator from inputting the total result acquisition request to displaying the result on the web screen. Also, only when the administrator requests re-aggregation, it is only necessary to search the body text field for mail whose contents are unknown in the subject field, so that the processing load on the server to be searched can be reduced. By searching the body text, it is possible to accurately classify more mails. By reflecting the mail searched in the text in the counting result, more accurate counting result can be obtained quickly. It is preferable that after the recounting step, the server includes a recounting result transmitting step of transmitting the recounting result to the manager terminal by e-mail. The administrator can grasp the initial result quickly and then can obtain a more accurate result.

According to the present embodiment, a keyword to be searched is added, and a tag as a classification heading and an importance level as a search priority can be set for the keyword. Optimal recalculation is possible depending on

According to the present embodiment, since the server specialized for the function is combined, it is possible to realize a server group having a high processing capacity as a whole, and even if the number of mails to be confirmed is large, the automatic mail classification is efficiently performed. It can be carried out.

に よ According to the present embodiment, it is a safety confirmation method that enables quick counting and is suitable for safety confirmation in an emergency. In addition to just alive confirmation, you can also find detailed information such as whether you are not injured or whether you can join the office by keyword, and for example, the same for keywords of the same type, such as “injury” and “injured” By tagging and counting for each tag, it can be classified by type. In a disaster, it is difficult to input the words as they are decided, and the input words may be blurred, but even in such a case, quick classification and aggregation can be performed. Since it can be counted for each group, for example, in a company with a large number of people, it is possible to quickly count how many people can enter the office and how many people have been injured in each department during a disaster. Further, since it is not necessary for the user's communication device to access the web site, the safety can be confirmed even if the user terminal is a communication device having no browser means.

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the invention. In addition, the constituent elements of the above embodiments can be arbitrarily combined without departing from the spirit of the invention.
