  The present invention relates to an information processing system, an information processing apparatus, and a program for causing a computer to execute a process for determining contents written to a document or an image by a user.

  In recent years, education support systems that can receive education while staying at home via the Internet have become widespread and used. In the educational support system, anyone who accesses the Internet can create, manage, and provide shared documents to anyone else accessing the Internet without having to join an institution. In addition, a technique for providing an open platform has been proposed (see, for example, Patent Document 1).

  In the conventional technique, since anyone can write to a shared document, it is necessary to determine whether or not the writing is inappropriate. However, unless the system administrator looks at the determination one by one, There was a problem of not becoming.

  FIG. 1 is a diagram illustrating a configuration example of an information processing system according to the present embodiment. The information processing system is an electronic education system capable of receiving education while staying at home via a network such as the Internet. The information processing system includes a plurality of terminals used by a user (user) on an education side, one or more terminals used by a user on an education side, a terminal used by an administrator of the system, a network, And an information processing apparatus. The information processing apparatus is an apparatus that accumulates and manages content shared by a plurality of users and contents written by the users with respect to the content.

  The user receiving the education may be a student, a student, a student, or a subordinate. The educating user may be a teacher, a leader, or a boss. Hereinafter, the user who receives the education will be described as a student, and the user who will receive the education will be described as a teacher.

  In FIG. 1, a student terminal 10 used by a student, a teacher terminal 11 used by a teacher, and an administrator terminal 12 are connected via a network 13, and a server 14 serving as an information processing apparatus is connected to the network 13. Has been. The student terminal 10 and the teacher terminal 11 are not limited to one, and may be two or more.

  The network 13 may be a wired network or a wireless network such as a wireless LAN (Local Area Network). Moreover, the network 13 may be comprised only from one network, and may be comprised from two or more networks connected to relay apparatuses, such as a router and a proxy server.

  The student terminal 10, the teacher terminal 11, and the administrator terminal 12 are a smartphone, a tablet terminal, a PC, or the like that includes an input device and a display device. These terminals are equipped with software for browsing Web sites on the Internet called browsers, and use browsers to display documents such as teaching materials, images such as images of blackboards, teachers, and the like. In addition, plug-in software such as Flash (registered trademark) player, for example, can be installed in order to reproduce and display the content in a browser. Hereinafter, the content will be described as a document.

  The student can log in to the system using the student terminal 10, display a document, and ask the teacher the meaning of an unknown word. This document is provided to each student. The teacher can use the teacher terminal 11 to log in to the system, display a document, and answer questions from students written in the document.

  The question depends on the content of the document. When the document is in a foreign language, the meaning of the word can be inquired. On the other hand, the teacher can answer the meaning of the word as an answer.

  An example of a screen displayed on the student terminal 10 after login is shown in FIG. The screen shown in Fig. 2 includes a button called "Private space" which is a private information storage area, a button called "Q & A space" that connects teachers and students in a non-real time Q & A room, and notifications from the administrator. Three buttons, “Notification and Manual”, are displayed for displaying the usage manual. When “private space” is selected, one-on-one exchange between students and teachers is possible. In the “Q & A space”, students can ask the teacher questions and get answers, but other students can also view the questions and answers.

  More specifically, the student uses the student terminal 10 and presses a button “Q & A space” to open a list of documents registered in the server 14 shown in FIG. Then, the student selects one file from the list of documents by double-clicking it. Thereby, a file as shown in FIG. 4 can be opened and displayed.

  On the screen shown in FIG. 4, an arbitrary page of the document is displayed at the center, and the page below shows how many pages the file is composed and how many pages are currently displayed. In addition, a field for writing a question is provided next to the displayed page. The student clicks and presses the button “question” or the like, writes a question regarding the content of the displayed page in the displayed questioner column, returns to the screen shown in FIG. The user presses the button and uploads the document in which the question is written to the server 14. The uploaded document is registered in a database as a storage unit held by the server 14. The database is not limited to the server 14 and may be outside the server 14. When it is outside the server 14, it may be directly connected to the server 14 with a cable or the like, or may be connected via the network 13.

  The teacher uses the teacher terminal 11 to select a document uploaded from the student, and when a question is written in the document, the teacher clicks a button such as “answer”. Then, the teacher writes the answer to the question in the displayed respondent column and uploads it to the server 14.

  The student uses the student terminal 10 to open the screen shown in FIG. 3, select a file, refer to the answer written in the document, and obtain an answer to the question. Here, an example has been described in which a student asks a question and a teacher answers. However, the present invention is not limited to this. For example, it is also used when a teacher adds comments such as advice and hints. Can do.

  Referring again to FIG. 1, the administrator uses the administrator terminal 12 to manage documents registered in the database, and deletes unnecessary documents and writing of inappropriate expressions. As shown in FIG. 5, the document is managed by a document management table. In the document management table, the creation date / time, file name, file path, file contents, etc. are managed in association with the user ID or user name for identifying the user. The file path is a character string indicating the location of the file on the database. The content of the file is a character string (text) to be displayed.

  Documents that are no longer needed include documents that have been instructed by a teacher to be unnecessary, and documents that are not used even after a certain period of time. Inappropriate expressions can include descriptions that slander others. Hereinafter, an inappropriate expression will be described as a slandering description.

  The server 14 receives access from students and teachers and determines whether or not it has access authority. For those who have access authority, access is permitted, and downloading of documents, writing to documents, and the like are enabled. On the other hand, for those who do not have access authority, access is prohibited and an error is returned. The presence or absence of access authority can be determined from authentication information such as a user ID input by a student or teacher when logging in.

  The presence or absence of access authority can be determined by whether or not the student or teacher inputs authentication information such as a user ID and matches the pre-registered authentication information. If the user has access authority, login is permitted. be able to.

  The server 14 periodically accesses a document uploaded by a person having access authority, determines whether the content written in the document is slanderous, and manages if it is slanderous. Notification to the person in charge. A method for determining and notifying slander will be described later.

  The administrator receives the notification using the administrator terminal 12, refers to the content, and determines whether to delete the writing. If the administrator determines to delete, the administrator downloads the document and deletes the writing. The administrator uploads the document whose writing has been deleted to the server 14.

  Since the server 14 extracts only slandering writing and notifies the administrator, it is possible to reduce the number of writings for the administrator to determine whether or not to actually delete, and to reduce the time and effort required for the determination. it can.

  The hardware configuration of the server 14 will be briefly described with reference to FIG. Note that the student terminal 10, the teacher terminal 11, and the administrator terminal 12 have the same configuration except for the input device and the display device, and thus the description of the hardware configuration is omitted.

  The server 14 includes a CPU 20, a ROM 21, a RAM 22, an HDD 23, and a network I / F 24 as hardware. The CPU 20 controls the entire server 14 and executes programs stored in the ROM 21 and the HDD 23 for the control. In addition, the CPU 20 executes a program for realizing processing such as the determination of the presence / absence of the access authority, the download / upload of the document, and the determination of the written content.

  The ROM 21 stores a boot program, firmware, and the like for starting the server 14. The RAM 22 provides a work area for the CPU 20. The HDD 23 stores and accumulates the OS, the above programs, and documents as files. Each program may be stored in the ROM 21. The network I / F 24 is connected to the network 13 and controls communication via the network 13.

  A functional configuration of the server 14 will be described with reference to FIG. The server 14 has a functional unit realized by the CPU 20 executing the above program, and includes an input processing unit 30, an acquisition unit 31, a calculation unit 32, a determination unit 33, and a notification unit 34 as the functional units. . The input processing unit 30 can be provided as necessary.

  The input processing unit 30 refers to the setting file describing the field names of the fields in the table for registering information such as the table name of the document management table, the creation date and time, and the creator, and acquires the information. The setting file also includes a threshold value set for a numerical value indicating the degree of inappropriateness of expression, and the threshold value is also acquired. The setting file is stored in, for example, a database, and information on the document is added when a new document is registered in the table.

  Based on the table name and field name acquired by the input processing unit 30, the acquisition unit 31 acquires information such as write contents, creation date and time, and creator from the corresponding field of the corresponding table managed in the database. The calculating unit 32 calculates the above numerical value from the written content acquired by the acquiring unit 31. The determination unit 33 determines whether the numerical value calculated by the calculation unit 32 exceeds the threshold acquired by the input processing unit 30.

  The notification unit 34 notifies the administrator terminal 12 of the content acquired by the acquisition unit 31 according to the determination result of the determination unit 33. The notification unit 34 notifies the determination result when the determination unit 33 determines that the threshold value is exceeded. At this time, the notification unit 34 can notify the written contents together.

  As illustrated in FIG. 8, the input processing unit 30 includes a condition input unit 40, a first threshold input unit 41, and a second threshold input unit 42. The condition input unit 40 analyzes the setting file, acquires a table name and a field name that are referred to in order to acquire information such as a writing content, a creation time, a creator, and the like, which are judgment targets of slander, and an acquisition unit 31 Enter against.

  The first threshold value input unit 41 analyzes the setting file, acquires a numerical boundary value indicating the degree of slander, as a first threshold value, and inputs it to the determination unit 33. The second threshold value input unit 42 analyzes the setting file, acquires a numerical boundary value representing the frequency of slander, as a second threshold value, and inputs it to the determination unit 33.

  The numerical value indicating the degree of slander can be, for example, the number of words representing slander that is included in the text as the written content. Words can be extracted in consideration of the flow of sentences constituting the text. For example, morphological analysis can be used as a method for discriminating words from sentences. As a method for obtaining the appearance frequency of the word, for example, text mining can be used. Since these methods are well-known methods, detailed description is omitted here.

  When the target is an image and includes a word representing slander, the word can be extracted after character recognition (OCR) processing. Also, if the document is an encrypted document, a word representing slander can be extracted after decryption. In addition, since this is an example, it is not limited to this, The number of an improper image, an unknown word, a symbol, etc. may be sufficient. Moreover, since the inappropriate degree differs for each word, a weight may be provided for each word.

  The frequency of slander can be, for example, the number of writings received from the same person per day, whose numerical value exceeds the first threshold. Since this is also an example, it is not limited to this, and may be 12 hours, a week, or the like.

  As shown in FIG. 9, the calculation unit 32 includes a first calculation unit 43 and a second calculation unit 44. The first calculation unit 43 calculates the numerical value from the written content acquired by the acquisition unit 31 and inputs the calculated numerical value to the determination unit 33. The determination unit 33 uses the numerical value input by the first calculation unit 43 and the first threshold input by the first threshold input unit 41 to determine whether the writing corresponds to a slander slander.

  The database can manage this determination result with a determination result table as shown in FIG. In the determination result table, each time each user performs writing, information on the writing date and time, the writing content, the calculated numerical value, the determination result, and the type of the writing target is acquired and managed. In this example, the numerical value is a numerical value representing the percentage of slandering words as a percentage of the total number of words constituting the sentence. The determination result is NG indicating the result of slander when the first threshold is exceeded, and OK indicating the result that it is not slander when it is equal to or less than the first threshold. Types of objects to be written are questions, answers, comments, and the like. The written content may be not only text but also an image, a file name, a file path, or the like.

  In determining whether or not a slander is a slander, if a weight is provided according to a word representing a slander that is set in advance, the weight can be taken into consideration. By determining in consideration of the weight, it is possible to more appropriately determine whether it is a slander slander.

  Referring to FIG. 9 again, the second calculation unit 44 acquires, for example, the determination result for one day among the determination results managed in the determination result table shown in FIG. Calculate the frequency.

  For example, when the user A writes 10 times a day, the first calculation unit 43 calculates the 10 numerical values and inputs them to the determination unit 33. The determination unit 33 determines whether each of the 10 corresponds to a slander slander. This determination result is registered and managed in the determination result table shown in FIG. The second calculation unit 44 calculates how many numerical values that exceed the first threshold value among the ten numerical values of the user A, and obtains the frequency.

  The determination unit 33 compares the frequency obtained by the second calculation unit 44 with the second threshold value input by the second threshold value input unit 42, and comprehensively considers the written content. It is determined whether it corresponds to. The reason why the written contents are taken into account is that there is a case where it is determined that the word corresponds to the slander slander although it does not hit the slander in the flow of the sentence.

  The determination of slander may be only determination using the first threshold, but when calculating the above numerical value, it may be erroneously determined as a word corresponding to slander. It is desirable to use the second threshold and make a determination in consideration of the written contents.

  The determination result of the determination unit 33 is a result for each user. For example, when the frequency of the user A is equal to or lower than the second threshold, it can be information that writing that is slandering is not performed. Further, the determination result can be information indicating that the user B tends to perform slandering writing when the frequency of the user B exceeds the second threshold. These are merely examples, and other information can be used, and numerical information, frequency information, and the like can also be included.

  As shown in FIG. 11, the notification unit 34 includes a mail transmission unit 45 and a push notification unit 46. The mail transmission unit 45 transmits the determination result to the administrator terminal 12 by electronic mail. The push notification unit 46 transmits the determination result to the administrator terminal 12 and notifies it by displaying it on the screen of the administrator terminal 12. For example, the user name of a user who is determined to have a tendency to slander is highlighted. Highlight display is a display method in which the character string representing the user and the background color are highlighted and displayed in reverse.

  The administrator may be notified only by e-mail from the e-mail transmission unit 45. However, if the administrator does not notice the e-mail, the slandering writing remains. For this reason, it is desirable to use it together with the notification by the push notification unit 46 so that the administrator immediately notices and can respond immediately.

  Processing for determining slander slander executed by the server 14 including the functional units shown in FIGS. 7 to 9 and 11 will be described with reference to FIG. The server 14 can execute this process at regular time intervals, and starts from step 1200 when it is time to execute the process. In step 1205, the condition input unit 40 analyzes the setting file, acquires the table name and field name, and inputs the information to the acquisition unit 31. In step 1210, the first threshold value input unit 41 analyzes the setting file, acquires the first threshold value, and inputs the first threshold value to the determination unit 33. In step 1215, the second threshold value input unit 42 analyzes the setting file, acquires the second threshold value, and inputs the second threshold value to the determination unit 33. Any of these orders may be performed first.

  In step 1220, the acquisition unit 31 acquires information such as the written contents, creation time, creator, etc., registered in the input field name of the input table name. The acquisition unit 31 inputs the acquired information to the first calculation unit 43. In step 1225, the first calculation unit 43 calculates a numerical value indicating the degree of slander from the written content, and in step 1230, the determination unit 33 inputs the numerical value from the first threshold value input unit 41. Compared with the first threshold value, it is determined whether the first threshold value is exceeded.

  If the first threshold value is exceeded, the process proceeds to step 1235, where it is determined to be applicable to slander. If not, the process proceeds to step 1240, where it is determined not to correspond to slander. In step 1245, the determination result is registered and accumulated in the determination result table shown in FIG. When the next frequency calculation is performed based on the result for one day, it waits until the result for one day is accumulated.

  In step 1250, the second calculation unit 44 calculates the frequency of slander slander using the determination results stored in the determination result table. In step 1255, the determination unit 33 comprehensively determines whether it falls under the slander slander based on the calculated frequency, the written content, and the second threshold value input by the second threshold value input unit 42.

  If it is determined that it corresponds, the process proceeds to step 1260, where the mail transmission unit 45 notifies the determination result by e-mail, and the push notification unit 46 highlights the user name on the screen of the administrator terminal 12, etc. Notify the judgment result. After the notification, the process proceeds to step 1265 and the process is terminated. This process can be performed again after a certain time has elapsed.

  With reference to FIG. 13, another functional configuration of the server 14 will be described. The server 14 has a functional unit realized by the CPU 20 executing the above-described program. As the functional unit, the input processing unit 30, the acquisition unit 31, the calculation unit 32, the determination unit 33, and the notification unit 34 described above. In addition, a usage control unit 35 is provided. Since the input processing unit 30 and the like have already been described, only the usage control unit 35 will be described here.

  When the frequency of slander calculated by the second calculation unit 44 exceeds a certain value, the usage control unit 35 blocks (locks) access from the user whose frequency exceeds the certain value. Control to prohibit use. For example, in response to the frequency exceeding a certain value, the usage control unit 35 can perform control to log off the user once and prohibit the login of the user thereafter. Therefore, an error is returned regardless of how many times the user tries to log in.

  By providing such a usage control unit 35, it is possible to lock a user who has made many slandering writings in a short time when an administrator is absent. The administrator can use the administrator terminal 12 to instruct the server 14 to release the lock, and the usage control unit 35 receives the instruction and controls to allow the user to log in. It can be performed. In order to perform this login, the server 14 can include an authentication unit 36 that accepts input of a user ID or the like as user information and authenticates the user. Since the authentication process is a well-known process, a detailed description thereof will be omitted.

  Processing for determining slander slander executed by the server 14 including the functional unit shown in FIG. 13 will be described with reference to FIG. The server 14 can periodically execute this process, and starts from step 1400 when it is time to execute the process. Steps 1405 to 1460 are the same as steps 1205 to 1260 shown in FIG. In step 1465, the usage control unit 35 determines whether the frequency calculated by the second calculation unit 44 exceeds a certain value. If it is determined that the value has been exceeded, the process proceeds to step 1470. If it is determined that the value has not been exceeded, the process ends in step 1475.

  In step 1470, the usage control unit 35 performs control to prohibit the login of the user who tends to perform the slander writing determined by the determination unit 33 and lock the user. Then, the process proceeds to step 1475 to end this process. Although not shown in FIG. 14, the usage control unit 35 can perform control for releasing the lock of the user in response to an instruction from the administrator.

  Since this system is a system that is used by three members, a student, a teacher, and an administrator, it is desirable to grant authority according to each role and limit the operable range.

  For example, if divided into two roles of student and teacher, the authority of the student is given to the student and all the authority is given to the teacher, the following problems arise. The first problem is that the teacher has all the authority, so the student's important documents are deleted carelessly or maliciously. The second problem is that it is difficult for students to ask questions because they can be viewed by all teachers and students. The third problem is that the authority of students and teachers is fixed and flexibility is low.

  In view of such a problem, a functional configuration as shown in FIG. 15 can be provided in order to give an appropriate authority according to the role. The server 14 illustrated in FIG. 15 includes an authority determination unit 37 as a function unit in addition to the input processing unit 30, the acquisition unit 31, the calculation unit 32, the determination unit 33, the notification unit 34, the usage control unit 35, and the authentication unit 36. Can be provided. Since the input processing unit 30 and the like have already been described, only the authority determination unit 37 will be described here.

  The authority determination unit 37 determines a role from the user ID input when the user logs in, and determines which operation of the user is to be given authority according to the determined role. The authority determining unit 37 can determine whether the role is a student, a teacher, or an administrator from the user ID with reference to the role table shown in FIG. Further, the authority determining unit 37 can grant the set authority according to the determined role with reference to the authority table shown in FIG.

  The authority table shown in FIG. 17 can be arbitrarily set by the administrator using the administrator terminal 12. Examples of the authority include question creation, answer creation, system setting, question deletion, and the like. Question creation and answer creation is the authority to create questions and answers. The system setting is an authority that can change settings related to document sharing, settings related to communication, settings related to users, and the like. Question deletion is an authority to delete a created question.

  In the example shown in FIG. 17, the question creation is performed only by the student, so that the authority is set only for the student, and the answer creation is performed only by the teacher, so the authority is set only for the teacher. Further, the system setting is set as an authority of only an administrator in order to appropriately operate the electronic education system. For question deletion, the administrator's authority is set so that the teacher cannot delete it due to carelessness, and the student's authority is also set so that the contents written by the teacher can be deleted by himself / herself. .

  Thus, by setting a low authority such as only creating an answer to the teacher, it is possible to reduce a risk of deleting an important document of a student based on carelessness or malicious intention. Further, by giving a high authority such as document deletion only to the administrator, it is possible to prevent inadvertent deletion and reduce the risk of the entire system. By changing the setting, the authority can be changed, so that the system can be given flexibility.

  The authority determining unit 37 can be configured as shown in FIG. 18 in order to realize these functions. The authority determining unit 37 includes an authority granting unit 47, an overtake right determining unit 48, a grouping unit 49, a function providing unit 50 and a receiving unit 51.

  The authority granting unit 47 determines a role from the user ID input when the user logs in, and grants authority for the operation set in the authority table according to the determined role. The student authority is granted to the student, the teacher authority to the teacher, and the administrator authority to the administrator.

  The pass right determination unit 48 determines whether or not the user's operation exceeds the granted authority. That is, it is determined whether or not the user operation is an operation for which authority is given in the authority table shown in FIG. The operations include creating a question, creating an answer, changing system settings, and deleting a question.

  The grouping unit 49 determines a group (group) to which the user belongs. The database holds, for each user, information such as high school / junior high school, grade, class, science / literacy, etc. as user information in association with a user ID, a user name, and the like. For this reason, the grouping unit 49 refers to the user information according to the set conditions and determines the group to which the user belongs. This information is an example, and is not limited to this information.

  The condition is a condition for dividing each group, and can be, for example, a grade or a class. The conditions can be set and changed by the administrator in the system settings.

  In this way, it is not just a student frame, but it can be viewed by students in the group by dividing it into smaller groups, but it cannot be viewed by students in other groups. It becomes easy. In particular, beginners feel embarrassed to ask questions and often cancel questions, but by making a small group, the number of questions can be reduced.

  The function providing unit 50 displays what is displayed on the user's terminal and what is not displayed based on the authority information granted by the authority granting unit 47 and the group information determined by the grouping unit 49. And provide the necessary functions. The database holds an item table associating items such as buttons to be displayed with authorities as shown in FIG. The function providing unit 50 refers to the item table shown in FIG. 19 and determines items to be displayed as functions and items to be hidden. In FIG. 19, the authority and the item are associated with each other. However, by associating with the group in addition to the authority, a function considering the group can be provided.

  Processing for determining an item with reference to the item table shown in FIG. 19 will be specifically described. If the user is a student, student authority is granted and the student authority is question creation and question deletion, so the “question” button and “delete” button are displayed, and the “answer” button and “system setting” button are Decide to hide. As a result, the function providing unit 50 normally displays a “question” button and a “delete” button as shown in FIG. 20 on the screen of the student terminal 10, and enables these buttons to be pressed. That is, enable those buttons and provide their functions. On the other hand, the function providing unit 50 grays out the “answer” button and the “system setting” button so that the buttons cannot be pressed.

  Here, an example of gray-out display has been described, but the present invention is not limited to this, and only buttons that can be pressed may be displayed, and the others may be completely hidden. The display / non-display is not limited to the button, and the writing column or the like may be displayed / hidden. The receiving unit 51 will be described later.

  With reference to FIG. 21, one process executed by the authority determination unit 37 will be described. This process is performed after the user logs in. Starting from step 2100, in step 2105, the user ID is input to the authority assigning unit 47 and the grouping unit 49. In step 2110, the authority granting unit 47 determines a role based on the input user ID, and grants the authority according to the role.

  In step 2115, the grouping unit 49 determines the group to which the user belongs based on the user information. Here, the group is determined after the authority is granted, but the processing order may be reversed or may be simultaneous.

  In step 2120, the function providing unit 50 displays what is displayed based on the authority information granted by the authority granting unit 47 and the group information determined by the grouping unit 49, and what is hidden. And provide the necessary functions. In step 2125, it is determined whether the user has logged off. If the user has not logged off, the process returns to step 2120. If the user has logged off, the process proceeds to step 2130, and the process ends.

  With reference to FIG. 22, another process executed by the authority determining unit 37 will be described. This process is also performed after the user logs in. Starting from step 2200, in step 2205, the user ID is input to the authority granting unit 47. In step 2210, the authority granting unit 47 determines a role based on the input user ID, and according to the role. Grant authority. Then, the authority granting unit 47 passes the authority information to the overpower determination unit 48.

  The server 14 includes a reception unit 51 that receives user operation information. In step 2215, the reception unit 51 receives operation information related to an operation from the user's terminal, and passes the operation information to the pass right determination unit 48. In step 2220, the overpass right determination unit 48 refers to the authority table shown in FIG. 17 based on the received operation information, and determines whether or not the authority range to which the user operation has been granted is exceeded. If not exceeded, the process proceeds to step 2230. If exceeded, the process proceeds to step 2225, and the reception unit stops receiving the user's operation information in response to the determination result of the excess right determination unit 48. When the passover determination unit 48 stops receiving the operation information, the contents operated by the user are not reflected on the screen of the user's terminal.

  In step 2230, it is determined whether the user has logged off. If the user has not logged off, the process returns to step 2215 and waits until the next operation information is received. On the other hand, if the user has logged off, the process proceeds to step 2235 and the process is terminated.

  Here, the processing of the authority grant unit 47 performed in step 2115 in FIG. 21 and step 2210 in FIG. 22 will be described in detail with reference to FIG. Starting from step 2300, in step 2305, based on the user ID used for login, the role table shown in FIG.

  In step 2310, it is determined whether or not the role is a student. If the role is a student, the process proceeds to step 2315 to refer to the authority table shown in FIG. Then, the process proceeds to step 2335 and this process is terminated.

  If it is not a student, the process proceeds to step 2320 to determine whether or not the role is a teacher. If it is a teacher, the process proceeds to step 2325 to refer to the authority table shown in FIG. 17 and assign a settable teacher authority. In step 2335, the process is terminated.

  If it is not a teacher, since it is an administrator, the process proceeds to step 2330, and a settable administrator authority is granted with reference to the authority table shown in FIG. Then, the process proceeds to step 2335 and this process is terminated.

  Communication between each terminal and the server 14 can be performed using a communication protocol such as HTTP (Hypertext Transfer Protocol), and the browser of each terminal requests the server 14 to download or upload a document. In addition, an API (Application Programming Interface) implemented in the server 14 can be called to send a request in the form of an HTTP Request. On the other hand, the server 14 can send a response in the form of HTTP Response.

  The calculation unit 32 may not be included in the server 14 and may be mounted on an external device. Communication between the server 14 and the external device can also be performed in the form of HTTP Request and HTTP Response, and in this case, the external device implements the API. The API may be modified or added with functions, and accordingly, the server 14 may need to be modified. In order to keep this correction to a minimum, the server 14 can include an API Wrapping unit as a change absorption unit for absorbing changes in the API of the external device.
