Description

  The present invention relates to a document management apparatus and a document management method for processing a document such as a message exchanged between users via a network, and a computer program. In particular, the present invention relates to a question between a large number of users such as an electronic bulletin board. The present invention relates to a document management apparatus, a document management method, and a computer program for managing messages exchanged in the form of repeated posting of opinions or answers.

  More particularly, the present invention relates to a document management apparatus and a document management method for processing information included in a message that is posted on an electronic bulletin board or the like, and a computer program, and particularly to an electronic bulletin board or the like. The present invention relates to a document management apparatus, a document management method, and a computer program that extract and process necessary information from a posted message including an action request.

  With the spread of information communication technology, various message exchange systems such as mail, electronic bulletin boards, and chats can be used, and information can be shared between specified or unspecified users via a network. Whereas e-mail is a one-to-one exchange, an electronic bulletin board is a system in which all participating users view messages written by a user, and users can obtain a wide range of opinions and answers by posting questions. It is possible to obtain the latest information at all times, it is excellent in the extensibility of information, and the information provided by many users can be shared by all. Electronic bulletin boards are generally divided into a number of forums according to the field they handle. Forums are often added, deleted, merged, or split on a wide area network such as the Internet.

  Since the electronic community represented by the electronic bulletin board system basically exchanges messages in the form of postings of questions from a certain user and opinions and answers from unspecified users who have viewed this, Information can be collected very efficiently compared to emails that are handled one-on-one, and the information obtained is diverse. In many cases, the number of recipients of posted messages is large, and in this respect, mailing lists, net news, and other virtual space communities are similar.

  This type of message exchange system is convenient because a wide variety of information is available, but on the other hand, a large number of posted messages are used by many people. There is a risk of end. For example, it is a very cumbersome task for each user to check a message that he or she needs to take some action without omission.

  In addition, since the message recipient is a large number of people, there is a possibility that the focus will be blurred to whom the content is addressed. For example, even if the user has read through the message, it is often not clear who requested it, and when the message is received, it may not be possible to instantaneously determine whether or not it is an action request for the user. After that, when other messages are posted one after another, the messages are buried as a piece of past information, leading to a situation where the requested action is overtaken.

  For example, a proposal has been made on an electronic information receiving apparatus that automatically analyzes contents of mail data, extracts topics from each mail data, categorizes the results and notifies the user in the form of a list (for example, , See Patent Document 1). However, since the mail data is classified by topic in the device, it is possible to understand the outline of the entire mail group, but after all, it is important if the user does not read the contents of the mail data. It is not possible to judge whether the information is correct.

  In addition, a document display method has been proposed in which importance is numerically expressed or prioritized with respect to a large number of electronic mails to prevent overlooking important mails (see, for example, Patent Document 2). However, although the method can sort e-mails in priority order, the meaning of the order is unclear to the user. After all, if the user does not read the contents of the mail data, the user cannot determine whether or not the mail contains an action request for himself / herself.

  Further, a schedule information extraction / editing apparatus that automatically reflects information related to the schedule included in the electronic communication information in the user's schedule has been proposed (see, for example, Patent Document 3). However, this apparatus is configured on the premise that it is managed as an individual schedule, and a message posted to a community having a large number of recipients cannot be suitably handled. For example, when the user determines that the schedule is irrelevant according to his / her own determination, the system cannot perform any further care.

  In addition, a proposal has been made for an e-mail system in which a special extension field for distinguishing an important message from ordinary e-mail is provided in a mail header and control is performed based on the header information (for example, (See Patent Document 4). However, by describing the display period and effective date of the important message by the extended field, it is possible to perform very fine display control, but it is assumed that an extended field is provided and an explicit designation is made.

  Also, information on the presence / absence of a reply request from the sender associated with the e-mail, information on the due date, and information on the presence / absence of a reply from the receiver to the sender are read, and the e-mail information is obtained based on the read information Proposals have been made on an e-mail management system to be displayed on the screen (see, for example, Patent Document 5). However, in this system, it is assumed that information on whether or not there is a reply is input in a specific format with the user being conscious.

  Currently, the electronic community is increasing, and the number of registered messages is enormous. In addition, messages posted to the electronic community are different from messages sent to individuals, and each reader has a different interpretation of the message (for example, whether or not it is regarded as an own action list). For this reason, it is necessary to make a selection by the reader himself. However, in many cases, it is determined that the determination cannot be made when the message is received, or it is determined that the message is irrelevant. As a result of deciding that it is irrelevant to you, it may cause a delay in the due date and cause a fatal hindrance to your work.

  The method to promote understanding of a large number of messages is to classify messages and list them by topic, to find the importance of emails, to sort and present them in order of importance, and to map the message information on the schedule There are a method for providing support, a method for discriminating and presenting an important message in an e-mail, a method for making an e-mail aware of the presence or absence of a reply, etc. An action request message cannot be extracted and referred to by a user in a timely manner.

  An object of the present invention is to provide an excellent document management apparatus and document capable of suitably processing information included in a message with a large number of people posted on a community, mailing list, net news, electronic bulletin board, or the like. A management method and a computer program are provided.

  A further object of the present invention is to provide an excellent document management apparatus, document management method, and computer program capable of extracting necessary information from a message including an action request posted on an electronic bulletin board or the like and suitably processing it. It is to provide.

  A further object of the present invention is to provide an excellent document management device, document management method, and computer program capable of preventing the recognition of action requests included in posted messages and managing the progress of requested items. There is to do.

  The present invention has been made in consideration of the above-mentioned problems, and a first aspect thereof is a document management apparatus for managing a large number of messages transmitted as recipients of a plurality of users, and storing means for storing the messages And message registration means for registering the message received from the user in the storage means, and for each message registered in the storage means, it is determined whether or not it is an action request, and the content of the action request for the message with the action request Is extracted and registered as additional information in the storage means, message search means for searching for a message from the storage means based on the additional information, and a search result by the message search means is displayed on the display device. A document management apparatus comprising message display means.

  The present invention relates to a document management apparatus for processing messages exchanged on a network. Specifically, the present invention relates to document management for processing messages posted to communities, mailing lists, net news, electronic bulletin boards, and the like. Device.

  A message to be posted to this type of electronic community must be selected by the reader himself because of the nature of receiving a large number of users. However, there are many cases where it is not possible to make a judgment at the time of receiving a message, or it is judged that the message is irrelevant. Also, if the message handling is completely entrusted to individual users who have viewed the message, the interpretation of the message will differ depending on the reader, so the decision as to whether or not to consider it as his own action list will be made for each user. As a result, there may be a delay in the deadline, resulting in a fatal hindrance to the business.

  On the other hand, the document management apparatus according to the present invention determines whether the message content analysis means is an action request message by analyzing the message content posted to the community by the system, and includes an action request. The determination result is held. And since the message based on a determination result is produced | generated and shown to a user as needed, the recognition omission of an action request can be prevented.

  In addition, the document management apparatus according to the present invention can also target messages stored on the server side that operates a community, an electronic bulletin board system, etc. In this case, it recognizes that each message has been requested. By managing the progress of requests and the progress of requested items on the server side, management on the action request side that posted the message can be facilitated.

  The message content analysis means estimates the action due date and the action requestee from the body of the message determined to be an action request, and registers it in the database as additional information. Specifically, the progress status of the action relating to a message for which an action request has been made is registered in the additional information in the storage means.

  Further, the message search means searches for a message that has passed or is due due to the additional information, and notifies the user of the search result by, for example, an alert mail.

  Further, when displaying the message list, the message display means highlights a message with an action request and prompts the user to call out.

  In addition, when the user who has viewed the message recognizes that it is an action requested or instructed to himself, the user can register the action requestee as additional information of the message through the message information editing means. it can.

  Further, a user registered as an action requestee can register the progress of the action as additional information of the message through the message information editing means.

  The document management apparatus according to the present invention manages a group of messages posted to the electronic community or the like by classifying them into tasks. The message content analysis means may not be able to identify the action requestee from the message determined to be an action request. In such a case, all members registered in the corresponding task are added as action requestees. What is necessary is just to make it register to information.

  When the user registered as the action requester determines that he / she is not the requestee, the user may be deleted from the action requester from the additional information of the message through the message information editing means. . In such a case, the requester of the action is notified of that fact.

  Further, the message display means can control a message to be displayed according to the authority corresponding to the role in the task. Specifically, the task leader displays all messages, the action requester displays the message he requested, and each task member displays the message he is the requestee. Like that.

  The second aspect of the present invention is a computer program written in a computer-readable format so as to execute processing on a computer for managing a large number of messages transmitted by a plurality of users as recipients. A message registration procedure for registering the message received from the user in the storage means to the computer, and whether each message registered in the storage means is an action request or not. A message content analysis procedure for extracting contents and registering them as additional information in the storage means, a message search procedure for searching for messages from the storage means based on the additional information, and a search result in the message search procedures are displayed on the display device Message display procedure and user A computer program characterized by executing the message information changing procedure for changing the additional information registered in the storage means in accordance with the instruction.

  The computer program according to the second aspect of the present invention defines a computer program described in a computer-readable format so as to realize predetermined processing on a computer system. In other words, by installing the computer program according to the second aspect of the present invention in the computer system, a cooperative action is exhibited on the computer system, and the document management apparatus according to the first aspect of the present invention. The same effect can be obtained.

  According to the present invention, an excellent document management apparatus and document capable of suitably processing information included in a message with a large number of people posted to a community, a mailing list, net news, an electronic bulletin board, or the like. A management method and a computer program can be provided.

  In addition, according to the present invention, an excellent document management apparatus, document management method, and computer program capable of extracting necessary information from a message including an action request posted on an electronic bulletin board or the like and suitably processing the extracted information. Can be provided.

  In addition, according to the present invention, there is provided an excellent document management apparatus, document management method, and computer program capable of preventing recognition of an action request included in a posted message and managing the progress of requested items. Can be provided.

  According to the present invention, action items can be automatically extracted from each message posted on a system such as an electronic bulletin board, and the action request messages extracted from the message group can be referred to in a timely manner. be able to. Therefore, by confirming omission of the action request included in the message, it is possible to support smooth progress of efficient business using various electronic communities.

  Other objects, features, and advantages of the present invention will become apparent from more detailed description based on embodiments of the present invention described later and the accompanying drawings.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  The present invention relates to a document management apparatus for processing messages exchanged on a network. Specifically, the present invention relates to document management for processing messages posted to communities, mailing lists, net news, electronic bulletin boards, and the like. Device.

  A message to be posted to this type of electronic community must be selected by the reader himself because of the nature of receiving a large number of users. However, there are many cases where it is not possible to make a judgment at the time of receiving a message, or it is judged that the message is irrelevant. Also, if the message handling is completely entrusted to individual users who have viewed the message, the interpretation of the message will differ depending on the reader, so the decision as to whether or not to consider it as his own action list will be made for each user. As a result, there may be a delay in the deadline, resulting in a fatal hindrance to the business.

  Therefore, in the document management apparatus according to the present invention, the content of the message posted to the community is analyzed by the system to determine whether the message is an action request, and when the action request is included, the determination result is retained. Like to do. Then, if necessary, a message based on the determination result is generated and presented to the user, thereby preventing an action request from being unrecognized.

  The document management apparatus according to the present invention can also process messages stored on the server side that operates a community or an electronic bulletin board system. In this case, management on the action request side that posted the message can be facilitated by recognizing that the request has been made for each message and managing the progress of the requested items on the server side. it can.

  FIG. 1 schematically shows a functional configuration of a document management apparatus 100 according to an embodiment of the present invention. The illustrated document management apparatus 100 includes a message registration unit 101, a message display unit 102, a message search unit 103, a message information storage unit 104, a message content analysis unit 105, and a message information editing unit 106. The user of the device 100 is, for example, a message registration user, a team leader, or the like, such as an action requester or an action performer. The document management apparatus 100 can be realized, for example, in the form of executing a predetermined server application on a general computer system such as a personal computer.

  The message registration unit 101 registers a message posted in a communication place provided to an unspecified number of users on a wide area network such as the Internet in a database.

  The communication place mentioned here is a system that handles a large number of messages such as an electronic community, a mailing list, net news, and an electronic bulletin board, and has the property that one message can be used by many people. For example, in the case of an electronic bulletin board, messages are exchanged in the form of posting a question sentence from a certain user and opinions and answers from unspecified users who have viewed this, and all participating users can view the message written by the user. can do. On the bulletin board, users can obtain a wide range of opinions and answers by posting questions, so that they can always obtain the latest information, have excellent information expandability, and provide information provided by many users. Can be shared with everyone. The task mentioned here is a communication place where not only an unspecified user but also a role such as a leader, a member, an observer, etc. can be set as a user for each task.

  The message display unit 102 displays various message formats such as a normal message list for each task, a list format in which action lists are grouped in time series, and a list format in which messages related to a specific task are listed. Or display. In each list display screen, an action request item and a message item are linked to other related pages such as editing message information (described later).

  The message search unit 103 searches for a message to be displayed from a database in which messages are registered.

  The message information storage unit 104 is configured with a database for registering messages posted in the electronic community.

  The message content analysis unit 105 applies natural language processing or the like to the registered message stored in the message information storage unit 104, analyzes the content, and determines the message type. Here, if it is determined that the message is an action request message, it is stored in the message database as additional information of each message including the due date. Furthermore, if it is possible to analyze the message and determine to whom the action request is addressed, it is registered in each message as an action requestee. Alternatively, if it is impossible to determine to whom the action request is addressed, the task message recipient (all task members) is registered in each message as the action requestee.

  The message information editing unit 106 edits / modifies information added to the message by automatic determination by the message content analysis unit.

  FIG. 2 shows a schematic procedure of a message content analysis process performed in the document management apparatus 100 shown in FIG. 1 in the form of a flowchart.

  First, a message stored in the database, that is, the message information storage unit 104 is read (step S1). The timing of executing the message analysis may be performed when the message is stored or periodically by accessing the database.

  Then, additional information such as a message type, a related date, and action performer information is extracted from the content of the read message (step S2).

  Examples of message content analysis methods include the following.

(1) A message including a message type and related terms in advance is defined as a message type.
(2) Perform morphological analysis or syntactic analysis, and specify or estimate information such as due date and requestee.

  In the case of the method (1), it is conceivable that the message information editing unit 106 manually registers additional information. Table 1 shows an example of a character string pattern for determining an action request message.

  3 to 5 show a state in which message pattern matching is performed using the character string pattern shown in Table 1 and additional information is extracted. In the example shown in FIG. 3, the message type is estimated as an action request / instruction based on the character pattern “Please”, and the due date is estimated as March 11, 2005 from the character pattern “By”. is doing. In the example shown in FIG. 4, the message type is estimated as an action request / instruction from the character string pattern “to do”, and the due date is estimated from this character string from “ni”. When an expression such as “This week” or “Tomorrow” is used instead of an absolute date and time, the absolute date and time is calculated from the message registration date and time. The database can be marked as “unknown” and the information can be manually supplemented later via the message information editing unit 106). In the example shown in FIG. 5, the message type is estimated as an event from the character string pattern of “date and time”, “location”, and “held”, and the due date is estimated as March 31, 2005.

  The additional information extracted in this way is registered in the database as additional information regarding each message (step S3).

  Table 2 shows a schema example of stored information of each message. In the table, the fourth column from the right is attribute information extracted directly from the message at the time of message registration, and the fifth and subsequent columns are fields for storing additional information extracted in step S2.

  Further, if the type of the request is an action request as a result of the message analysis, the requestee, the due date, the progress status, and the like are separately managed. Table 3 shows an example of a schema for storing additional information related to the action request message. The document management apparatus 100 according to the present embodiment can confirm the status of the action request by an action requester, a team leader, or the like using the information shown in the table.

  The document management apparatus 100 according to the present embodiment determines whether the message is an action request message by analyzing the message content posted to the community by the system, and holds the determination result if the action request message is included. To do. Then, if necessary, a message based on the determination result is generated and presented to the user, thereby operating to prevent recognition of the action request. Hereinafter, an operation example of the document management apparatus 100 will be described.

Operation example 1:
The message content analysis unit 105 extracts a message from the database, analyzes the content, and determines whether it is an action request (request, instruction, event holding, etc.). From the analysis result, if it is a message for an action request, if there is a request or instruction due date, event date and time, etc., it is extracted. As additional information of the message, an attribute indicating that it is an action request, a time information attribute related to the action request Are registered in the database (see Table 2).

  When the user accesses the document management apparatus 100, for example, on the top page of the message display unit 102, “xx request / instruction / event” (xx is “today”, “this week”, “this month”, etc.) ) As a list from the message database. Alternatively, instead of displaying directly on the top page, link information from the top page may be displayed.

Operation example 2:
In addition to presenting the content of the message of the action request via the message display unit 102, the message search unit 103 displays the message that has reached a certain timing (for example, within a predetermined time until the due date) as message information. A search is made from the database of the storage unit 104 (for example, a search is made from Table 2), and a message list describing requests / instructions / events is notified as an alert mail.

Operation example 3:
Further, when displaying a message on the message display unit 102, the information added by the message content analysis unit 105 is added to the message title to add “*** request ***”, “*** instruction **”. “*” Or the like is highlighted (see FIG. 6) to alert the user (the person who requested the action).

Operation example 4:
When a user views a message via the message display unit 102 and recognizes that it is an action requested or instructed to himself / herself, as message additional information via the message information editing unit 106 It is written as the “request / instruction subject” provided (see Table 3). In addition, after a user who is a requestee of an action takes an action for the request, information on the progress is written in the database in the message information storage unit 104 through the message information editing unit 106.

  As a result, the requester of the action confirms the action request status by referring to Table 3 from the database for a specific message, and determines whether the action request is accepted or who is accepted. You can easily manage the progress.

  Further, the additional information added by the message content analysis unit 105 is corrected by the message information editing unit 106, thereby preventing an error in information automatically determined by the document management apparatus 100.

Example 5 of operation:
In addition to the action requester himself / herself being able to confirm the status of the action request, the message search unit 103 searches the database in the message information storage unit 104 for action items related to the specified specific person, and the message is displayed via the message display unit 102. Can be presented.

  For example, the team leader can list the action requests handled by the members of his / her task and know who is doing what action.

Example 6 of operation:
As described above, when displaying the message list on the message display unit 102, the title of a message for which an action request has been made is highlighted. Further, the message search unit 103 can search the database for a message including an action request whose due date has passed (or the due date is approaching) and notify the requester of the action.

Example 7 of operation:
As described above, the message content analysis unit 105 analyzes the content of each message, and registers the due date, the person requested to take the action, and the like as additional information in the database.

  On the other hand, when each user views an action item related to himself / herself through the message display unit 102 or receives an alert mail, when the user determines that the action is not related to himself / herself, Through the message information editing unit 106, the information can be deleted from his list. When the action requestee is deleted, the action requester is notified to that effect.

Example 8 of operation:
The message content analysis unit 105 analyzes each message to determine whether it is an action request. If it is determined to be an action request, the message content analysis unit 105 extracts a due date and determines who the message is for The requester is also registered in the database in the message information storage unit 104 as additional information (see Table 3). For example, if there is a direct expression such as “To Mr. XX” or “Please △ Mr. △” in the message body, the individual can be easily identified. In addition, when the requested person of the action cannot be specified, all the members registered in the task are determined as requested persons. In this case, as described in the operation example 7, when it is determined that each user is not related to the user, the information can be manually deleted through the message information editing unit 106.

  In each of the above operations, the access right evaluation of the referenceable action list is the message access right. In this way, it is conceivable to control the public contents of the message contents. For example, in an electronic community in which access right information is defined for each task, display control of action item contents can be performed.

  As described above, the document management apparatus 100 according to the present embodiment analyzes a large number of messages posted to an unspecified user in the electronic community, automatically discriminates and manages action requests, and also displays the message display unit 102. By displaying the action list through the user, each user can prevent an excessive amount of action requests and can support efficient progress of business using the electronic community.

  The message display unit 102 displays various message formats such as a normal message list for each task, a list format in which action lists are grouped in time series, and a list format in which messages related to a specific task are listed. Or display. In each list display screen, the action request item and the message item are linked to other related pages such as editing message information.

  FIG. 7 shows a configuration example of an action list displayed by the message display unit 102 as a top page. In the example shown in the figure, the action request with high urgency is displayed first, such as today's action, tomorrow's action, etc., then this week's action, next week's action, and subsequent actions, etc. Provide a link.

  For example, when a user A logs in to the document management apparatus 100, the message search unit 103 searches the database, extracts an action request related to the user, and selects a personal portal page including this in the TODO list. The message is generated and displayed on the message display unit 102 (see FIG. 8).

  When the user A selects a specific task in the TODO list of the portal page, a list of messages related to the task is displayed (see FIG. 9). As described with reference to FIG. 6, when a message is displayed, the information added by the message content analysis unit 105 is added to the title of the message and highlighted (described above). The user A does not overlook the action for which the user A is the requestee.

  In the task page of this TODO, the display can be controlled by changing the items that can be displayed or operated according to the authority of the accessing person such as the task leader, the TODO client, or the member.

Leader: All TODO items Client: Only items requested by me Member: Only items for which I am a requestee

  Here, when a specific message is selected on the message list in the task page, a transition is made to a message editing screen for replying to the message (see FIG. 10). Of course, not only reply messages but also new messages can be added. When the message has been posted, the task page returns to the task page as shown in FIG. 9, but the additional message is reflected in the message list.

  When user A selects a specific action request item from the to-do list on the task page, the screen transitions to a screen for confirming the progress (see FIG. 11). On this screen, the progress of the task can be confirmed by the leader of the corresponding task, the TODO requester, or each member, and operations such as addition or deletion of the requestee can be performed.

  The present invention has been described in detail above with reference to specific embodiments. However, it is obvious that those skilled in the art can make modifications and substitutions of the embodiment without departing from the gist of the present invention.

  The present invention can be suitably applied to various document management systems such as an electronic community, a mailing list, net news, and an electronic bulletin board that handle a large number of messages and each message is used by a large number of people. In addition, by confirming omission of the action request included in the message, it is possible to support the smooth progress of efficient work using various electronic communities.

  In short, the present invention has been disclosed in the form of exemplification, and the description of the present specification should not be interpreted in a limited manner. In order to determine the gist of the present invention, the claims should be taken into consideration.
