Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an information distribution system that distributes information written on an electronic bulletin board to each user.
[0002]
[Prior art]
Conventionally, a system in which information is exchanged among a large number of users has been proposed. For example, according to the broadcast distribution system described in Patent Literature 1 below, information is exchanged by distributing a document (information) created by one user to many other users by e-mail. Can do. In addition, a BBS (Electronic Bulletin Board) that collects information provided by each user and distributes it to the applicant has been proposed.
[0003]
A system for distributing these information is often constructed and operated by a provider such as an Internet provider using its own hardware and software resources. This is because advanced technology and a lot of cost are required to construct and operate the system.
[0004]
Then, such an operator uses the system to provide a service for opening a BBS or a website for a person who wants to distribute information (for example, an organization such as a school, a circle, or an information providing service company). providing. That is, such an organization has established a BBS or the like by borrowing a part of the business system. As a result, these organizations can easily establish a BBS or the like without high technical knowledge.
[0005]
In recent years, mobile phone terminals with digital cameras and PDAs (Personal Digital Assistants) with small microphones are becoming more and more popular, and many large-sized data such as images, video, audio, and multimedia data are used. There is a growing need for casual exchange between users.
[0006]
[Patent Document 1]
JP 2002-163202 A
[0007]
[Problems to be solved by the invention]
However, if a large number of large-sized data such as multimedia data is to be distributed at the same time, the system is overloaded and processing may be delayed. If it does so, malfunctions, such as becoming impossible to deliver the information which needs urgent immediately will arise.
[0008]
In order to suppress the occurrence of processing delay, it is conceivable to determine which data (information) is to be distributed at which timing. In the conventional system, it is technically difficult for the organization that establishes the BBS to determine the timing. Therefore, the operator who operates the system determines the timing.
[0009]
However, this increases the burden of system operation on the part of the operator. In addition, since there are more opportunities for operators to touch information exchanged within each organization, it cannot be said that there is a risk of information leaking from the operators.
[0010]
Therefore, in order for a business operator to obtain a high level of trust from the organization with which the service is provided, it is desirable to build a system that does not require the business operator to participate as much as possible about the information exchanged within that organization. . For this purpose, a system that is easy to handle is required.
[0011]
The present invention has been made in view of such problems, and an object thereof is to provide a system capable of efficiently and easily delivering information to each user participating in the BBS even if the information is large in size. .
[0012]
[Means for Solving the Problems]
An information distribution system according to the present invention is an information distribution system that establishes a plurality of electronic bulletin boards and distributes information to users, and includes access right information indicating the access right of each user to the electronic bulletin board and e-mail of each user. A user database for storing addresses, priority setting means for setting a priority for distributing information for each electronic bulletin board, and when a request for distributing information to a user is made to the electronic bulletin board Based on the priority of the electronic bulletin board set by the priority setting means, the request addressed to the electronic mail address of the user indicated in the access right information that the electronic bulletin board is accessible And a mail delivery command means for giving a command to deliver the information related to the mail server.
[0013]
Alternatively, a user database that stores the user's e-mail address, a log database that stores the content or title of information distributed to the user in the past for each electronic bulletin board, and a request to distribute information to the user The content or title of the information related to the request is included in the content or title of the information delivered to the user in the past on the electronic bulletin board stored in the log database when it is made to the bulletin board By checking whether or not there is a possibility that information having the same content or title information as the information related to the request has been distributed in the past, and the double request checking means When it is determined that there is a possibility that information of the same content or title as the information related to the request has been distributed in the past Confirmation of whether or not the information related to the request may be distributed to the request source of the request, and confirmation that the information related to the request may be distributed by the distribution confirmation unit Is obtained, the mail server is instructed to deliver information related to the request to the e-mail address stored in the user database. If the confirmation is not obtained, the request is issued. And a mail delivery command means for canceling.
[0014]
Alternatively, for each user, a user database that stores an e-mail address of the user and distribution availability information indicating whether or not the e-mail may be distributed to the user, and the electronic that is a distribution destination of the distributed e-mail An error receiving means for receiving a delivery error indicating that a mail address does not exist; and the delivery permission information of the user associated with the e-mail address indicated in the delivery error when the delivery error is received by the error receiving means Is stored in the user database when a request to distribute information to the user is made to the electronic bulletin board. The information related to the request is delivered by e-mail with the e-mail address as a destination. The mail delivery command means for instructing the mail server, and the user related to the delivery permission information indicating that the email is not delivered among the email addresses stored in the user database from the destination And delivery command control means for controlling the mail delivery command means so as to be excluded.
[0015]
Alternatively, when the user logs on to the information distribution system, the distribution permission / non-permission determining means for determining whether or not the distribution permission / non-permission information of the user indicates that the electronic mail is not distributed, and the distribution permission / non-permission determining means Warning means for delivering a warning message that the user's e-mail address does not exist to the user's terminal device related to the delivery permission information when it is determined that the delivery information does not deliver the email And e-mail address updating means for updating the e-mail address of the user stored in the user database to the new e-mail address when a new e-mail address is designated by the user. Do it.

FIG.
[0027]
The user database 1D1 in FIG. 2 stores a user information table TL1 as shown in FIG. 3, a group information table TL2 as shown in FIG. 4, and an affiliation member table TL3 as shown in FIG. It manages personal information regarding users who use the BBS, that is, students, parents, teachers, etc. of the school.
[0028]
In the user information table TL1 of FIG. 3, an e-mail address 81a, an error mail flag 81b, a password 81c, and a name 81d of each user are stored in association with the user ID. The error mail flag 81b indicates whether the user's e-mail address 81a is invalid or valid. That is, when the error mail flag 81b is “1”, the corresponding e-mail address 81a is invalid, that is, does not exist, and even if an e-mail is transmitted to the e-mail address 81a, the address is unknown and returns. Means that. On the other hand, “0” means that the e-mail address 81a is valid.
[0029]
In the group information table TL2 of FIG. 4, access right information 82a for each group is stored in association with the group ID. In the present embodiment, one group is formed for each class (one set per year, one set per year,...), A group of teachers, a group of parents, or an organization such as PTA, government, or secretariat. is doing.
[0030]
The access right information 82a indicates the access right to each BBS (BBS1, 2,..., N) given to the group and the user (member) to which the group belongs. Information indicating users belonging to each group is stored in the member table TL3 in FIG.
[0031]
Information other than the error mail flag 81b in the user information table TL1 and the contents of the affiliation member table TL3 are registered or updated by the user information registration unit 105 in the following procedure.
[0032]
That is, the user displays the information registration screen HG1 of FIG. 6 on his / her terminal device 2, inputs predetermined items in each text box, and clicks the registration button BN11. The group ID can be input by selecting from the group list LS1 shown in FIG. A plurality of group IDs can be selected. The group list LS1 is displayed when the search button BN12 on the information registration screen HG1 is clicked.
[0033]
Then, the user information registration part 105 receives the input content from the terminal device 2, and registers or updates the content of the user information table TL1 or the member table TL3 based on this. Registration or update may be performed by file transfer or the like instead of via a Web page such as the information registration screen HG1.
[0034]
Also, the access information 82a of the group information table TL2 in FIG. 4 is registered or updated by the user information registration unit 105. That is, a user such as a group representative, a teacher, or a portal site administrator performs a predetermined operation to cause the terminal device 2 to display the contents of the group information table TL2. Here, the access right information 82a is changed, and the changed point is transmitted to the information distribution system 1. When a new group is registered, predetermined items are input into each text box of the group registration screen HG2 as shown in FIG. 8 and the input content is transmitted to the information distribution system 1. Then, the user information registration unit 105 updates or registers the group information table TL2 based on the transmitted content.
[0035]
The log database 1D2 stores information that has been uploaded (written) in the past, that is, news title, content (text), date, time, writer, and the like as log information 7L for each BBS.
[0036]
The logon processing unit 107 in FIG. 2 performs processing for authenticating a user who uses a school portal site. Such processing is performed in the following procedure. The user designates the URL (Uniform Resource Locator) of the portal site in the Web browser of the terminal device 2. Then, the logon processing unit 107 displays the logon screen HG3 shown in FIG.
[0037]
The user inputs his / her user ID and password in the text box of the logon screen HG3. Then, the logon processing unit 107 accesses the user information table TL1 (see FIG. 3), and performs user authentication by determining whether or not the input user ID corresponds to the password. A top page screen HG4 as shown in FIG. 10 is displayed on the terminal device 2 of the user who has obtained user authentication.
[0038]
In addition to the name TT2 of the logged-on user, a hyperlink HL41 to each BBS that can be accessed by the user is embedded in the top page screen HG4. Therefore, the contents of the top page screen HG4 are different for each logged-on user.
[0039]
The top page screen HG4 is described in a language for a Web page such as HTML or Java (registered trademark), for example. The code for the name TT2 is generated based on the user information table TL1 (see FIG. 3). The code of the portion of each hyperlink HL41 is generated based on the group information table TL2 (see FIG. 4), the belonging member table TL3 (see FIG. 5), the BBS information table TL4 (see FIG. 11) described later, and the like. .
[0040]
The information registration screen HG1 shown in FIG. 6, the group registration screen HG2 shown in FIG. 8, the logon screen HG3 shown in FIG. 9, and each screen described later (see FIGS. 13, 14, etc.) are also top page screens. Similar to HG4, it is described in a language for Web pages such as HTML.

FIG. 15 is a diagram illustrating an example of the configuration of the job generation unit 103, FIG. 16 is a diagram illustrating an example of the job 72 stored in the queue storage unit 1D3, and FIG. 17 is each mail server, distribution priority, and detouring FIG. 18 is a diagram illustrating an example of a relationship with the destination, FIG. 18 is a diagram illustrating an example of a warning screen HG7, and FIG. 19 is a diagram illustrating an example of a user information change screen HG8.
[0042]
Returning to FIG. 2, the BBS management unit 10 </ b> B performs processing for management of each BBS established by this school. Specifically, a process of writing (uploading) information (news) provided by the user to the BBS, a process of distributing the news written to the BBS to the user, and a BBS storing information for managing the BBS The information table TL4 is managed.
[0043]
In the BBS information table TL4, as shown in FIG. 11, display titles 84a and priority information 84b for each BBS are stored. The display title 84a is used for displaying the hyperlink HL41 (see FIG. 10) to the BBS described above and the title (see FIG. 13) of the BBS top screen HG5 described later. The priority information 84b is used to determine the priority for distributing the news written in the BBS to the user as an electronic mail. This will be described later.
[0044]
This priority information 84b can be determined by a school teacher or a portal site administrator. For example, the priority information 84b is determined by the following procedure. First, the school teacher (user) logs on to the school portal site using his / her user ID, and causes the terminal device 2 to display the top page screen HG4 of FIG. Then, the hyperlink HL42 is clicked.
[0045]
Then, the priority setting unit 101 in FIG. 2 displays the contents of the BBS information table TL4 on the terminal device 2 as a BBS management screen. The user inputs the desired priority information 84b. At this time, the priority setting unit 101 updates the BBS information table TL4 based on the input content. Note that the same procedure is performed when the display title 84a is changed.
[0046]
The process of uploading the news provided by the user to the BBS and the process of distributing the news to the user in the BBS management unit 10B will be described later.
[0047]
As shown in FIG. 12, the distribution request receiving unit 102 includes a request information receiving unit 121, a double request checking unit 122, and a distribution confirmation unit 123, and uploads news to the BBS and distributes it to other users. A process of accepting a request for power is performed. Such processing is performed in the following procedure, for example.
[0048]
A user who is a news provider logs on to the school portal site by performing a predetermined operation, and causes the terminal device 2 to display the top page screen HG4 of FIG. Click the hyperlink HL41 of the BBS where you want to upload (publish) the news, and access that BBS. At this time, a BBS top screen HG5 as shown in FIG. Here, when the registration button BN51 is clicked, an upload screen HG6 having a form for uploading news is displayed as shown in FIG. However, if the user does not have a write right for the BBS, a message that there is no access right is displayed instead of the upload screen HG6.
[0049]
The user inputs the title (title) and body of the news to be provided in the text boxes TX61 and TX62. If you want to provide binary data (binary file) such as still images, moving images, audio, or multimedia data related to news, enter the location (path) or file name of the binary file in the text box TX63. . Further, check boxes CB61 and CB62 are checked or any button in the selection button group SB61 is selected as necessary. These check boxes and selection buttons will be described later. Then, the transmission button BN61 is clicked.
[0050]
As a result, information indicating the input, checked, or selected content and the upload destination BBS is transmitted from the terminal device 2 to the information distribution system 1 as distribution request information 71 and received by the request information receiving unit 121 in FIG. Is done.
[0051]
The double request check unit 122 checks based on the log information 7L stored in the log database 1D2 whether news similar to the news that the user wants to provide has been uploaded to the BBS before. To do.
[0052]
That is, if the title and text shown in the distribution request information 71 are matched with the title and text in the log information 7L and a match is found, there is a possibility that similar news has been uploaded before. Determine that there is. Alternatively, when at least one of the title and the text matches each other, the determination may be made in this way.
[0053]
In this case, the delivery confirmation unit 123 notifies the terminal device 2 of the user who is the request source that there is a possibility that the news delivery request may be made twice. If the user makes a double request by mistake, the user requests to cancel the current request. Thereby, the process for the distribution request information 71 is stopped. If not, or if it is desired to repost the same news, the check box CB62 on the upload screen HG6 in FIG. 14 is checked and the send button BN61 is clicked. As a result, a confirmation notification 73 indicating that the distribution may be performed is transmitted from the terminal device 2 to the distribution confirmation unit 123, and the process performed by the BBS management unit 10B described below is performed.
[0054]
Based on the received distribution request information 71, the BBS management unit 10B uploads the title and text of the news provided by the user to the designated BBS. If there is a binary file, it is stored in a predetermined directory. Thereby, each user can receive provision (distribution) of the newly provided news from the top page screen HG4 (see FIG. 13) of the BBS. The log information 7L stored in the log database 1D2 is updated before or after the upload process. That is, the title and text of this news are written in the log information 7L.
[0055]
The received distribution request information 71 indicates “Title and contents posted in mail” or “Contact mail with new information” (ie, buttons other than “no mail” in the selection button group SB61 in FIG. 14). If selected, an e-mail notifying that new information (news) has been provided by the processing of the job generation unit 103, the mail delivery command unit 104, and the user information registration unit 105 described below M1 is generated and distributed to a predetermined user.
[0056]
As shown in FIG. 15, the job generation unit 103 includes a group determination unit 131, a nonexistent address determination unit 132, an e-mail generation unit 133, a priority determination unit 134, and the like. ) And delivery priority.
[0057]
The group determination unit 131 determines a group to which the electronic mail M1 is to be distributed. That is, a group to which “Read” access right is assigned to the BBS (news upload destination BBS) specified in the distribution request information 71 received by the distribution request receiving unit 102 is shown in the group information table TL2 of FIG. Determine based on.
[0058]
The non-existing address discriminating unit 132 extracts the e-mail address 81a of the member (user) belonging to the discriminated group from the user information table TL1 in FIG. 3 based on the belonging member table TL3 in FIG. Further, an e-mail address 81a in which an error mail flag 81b is set (indicating “1”) is determined. That is, the e-mail address 81a determined to be invalid (absent) among the extracted e-mail addresses 81a is determined. Then, the e-mail generation unit 133 is notified of the e-mail addresses 81a corresponding to the e-mail addresses 81a that are considered invalid.
[0059]
The e-mail generation unit 133 generates an e-mail M1 based on the title and the text indicated in the distribution request information 71. Also, the e-mail address 81a notified from the nonexistent address discriminating unit 132 is specified in the Bcc (Blind Carbon Copy) field of the e-mail M1. When there is a binary file (that is, when an attached file is designated on the upload screen HG6 in FIG. 14), this is set as the attached file of the e-mail M1.
[0060]
However, if “contact mail with new information” is selected on the upload screen HG6 in FIG. 14, a message indicating that the title and new information (news) indicated in the distribution request information 71 have been uploaded to the BBS. Only in the electronic mail M1, and the text and binary file shown in the distribution request information 71 are not used.
[0061]
The priority determination unit 134 determines the priority PR for transmission (distribution) of the generated electronic mail M1. Specifically, it is determined based on the priority information 84b corresponding to the BBS to which the same content (news) as the electronic mail M1 set in the BBS information table TL4 of FIG. 11 is uploaded. If the user who requested the distribution has checked the check box CB61 on the upload screen HG6 in FIG. 14, a higher priority PR than the setting in the BBS information table TL4 is given. For example, “1” is given regardless of the setting of the BBS information table TL4.
[0062]
The e-mail M1 thus generated and the determined priority PR are associated with each other and stored in the queue storage unit 1D3 as one job 72, as shown in FIG.
[0063]
Returning to FIG. 2, the mail delivery command unit 104 sends (distributes) the email M1 to each user by sequentially sending the jobs 72 stored in the queue storage unit 1D3 one by one to the mail delivery unit 10S. The mail delivery unit 10S is commanded as described above.
[0064]
The command is made based on the following rules. (1) Commands are issued in order from the job 72 with the lowest priority PR. (2) A symbol “-” indicates a job 72 (e-mail M1) that does not need to be distributed with priority. Therefore, such an e-mail M1 is often distributed in a time zone where the network traffic is low, such as at midnight. (3) If there are a plurality of jobs 72 with the same value and priority PR, the job 72 stored first in the queue storage unit 1D3 is preferentially processed.
[0065]
According to these rules, in the example shown in FIG. 16, processing is performed in the order of jobs 72 having job names “1”, “2”, “4”, and “3”, respectively. However, when a new job 72 is stored in the queue storage unit 1D3, the job 72 to be processed next is determined again.
[0066]
When there are a plurality of mail delivery units 10S, that is, when a plurality of mail servers are provided in the information delivery system 1, the job 72 can be distributed to each mail delivery unit 10S (mail server) for processing.
[0067]
For example, as shown in FIG. 17, a different mail server delivery priority value is set for each mail server, and the job 72 is assigned a mail server delivery priority having the same value as the priority PR value of the job 72. You may make it send to the mail server which has. Alternatively, the jobs 72 are rearranged according to the rules (1) to (3) above, and the jobs 72 are distributed to the mail servers “1”, “2”,..., “N” in descending order of priority PR. Also good.
[0068]
Further, when the mail delivery unit 10S goes down and there is no response, the job 72 may be sent to another mail delivery unit 10S indicated as the “detour destination” of the mail delivery unit 10S.
[0069]
Returning to FIG. 2, the mail delivery unit 10 </ b> S transmits (distributes) the email M <b> 1 to the email address indicated by the destination (Bcc) based on the job 72 sent from the email delivery command unit 104.
[0070]
The error receiving unit 106 receives error information 74 related to an unknown destination error for the electronic mail M1 distributed by the mail distribution unit 10S. Such error types include a “user unknown” error and a “host unknown” error. In the error information 74, in addition to the type of error, an unknown e-mail address is shown.
[0071]
The flag update unit 109 sets the error mail flag 81b stored in the user information table TL1 in FIG. 3 corresponding to the electronic mail address (81a) indicated in the error information 74. That is, it is updated to “1”. As a result, the e-mail M1 is not transmitted to the e-mail address 81a in the future. In order to receive the delivery of the electronic mail M1 again, the error mail flag 81b must be changed as follows.
[0072]
The user logs on to the school portal site by the terminal device 2. When logging on, the logon processing unit 107 checks the error mail flag 81b corresponding to the user ID of the user. When the error mail flag 81b is set, the non-existence warning unit 108 transmits a message to the terminal device 2 that the electronic mail address does not exist (is invalid).
[0073]
Then, a warning screen HG7 as shown in FIG. Further, the user clicks the display button BN71 to display the user information change screen HG8 shown in FIG. 19 and inputs a correct e-mail address in the text box TX62, and then clicks the change button BN81. At this time, the input correct electronic mail address is transmitted to the information distribution system 1. Then, the user's email address 81a stored in the user information table TL1 is changed to the transmitted correct email address.
[0074]
FIG. 20 is a flowchart for explaining an example of the flow of the news distribution process by the electronic mail M1, and FIG. Next, the flow of processing of the information distribution system 1 will be described with reference to the flowcharts shown in FIGS.
[0075]
A user who wants to provide information (news) to another user designates the BBS on the top page screen HG4 of FIG. 10, and further inputs the title and text of the news on the upload screen HG6 as shown in FIG. .
[0076]
Then, in FIG. 20, the information distribution system 1 receives the input content from the terminal device 2 (# 11), and determines whether similar news has been uploaded to the BBS in the past based on the log information 7L. (# 12).
[0077]
If the log information 7L includes the same title or body text entered in the terminal device 2, it is determined that similar news may have been uploaded in the past (Yes in # 12). Then, the user who is the providing source is requested to confirm whether or not the distribution is double delivery (# 13). The user confirms the content of the news. If the confirmation result that the news may be distributed is obtained (Yes in # 13), the information distribution system 1 uploads the news to the BBS designated by the user (# 15), and further The processing after step # 16 is continued. If the confirmation result is not obtained (No in # 13), the process of providing news to each user is stopped (# 14).
[0078]
Processing for transmitting the content of the news or a message that the news has been newly uploaded to the BBS as the electronic mail M1 is performed (# 16, # 17). That is, the group having the access right (Read right) to the BBS designated by the user is extracted from the group information table TL2 in FIG. 4, and the e-mail address 81a (see FIG. 3) of the member (user) belonging to the group is electronically stored. The distribution destination of the mail M1 is determined (# 16). However, the e-mail address 81a of the user for whom the error mail flag 81b is set is excluded. Then, the electronic mail M1 is distributed to each electronic mail address 81a (# 17).
[0079]
An error with unknown destination may be received after delivery of the e-mail M1 (Yes in # 18). In this case, the user information table TL1 is updated so as to set the error mail flag 81b corresponding to the electronic mail address 81a indicated by the error (# 19).
[0080]
When the error mail flag 81b is restored (turned off), processing is performed according to the procedure shown in FIG. After the user logon process (# 21), the information distribution system 1 checks whether or not the user's error mail flag 81b is set (# 22). When standing (Yes in # 22), a warning message is notified to the user (# 23). When a correct e-mail address designation is received from the user (# 24), the e-mail address 81a of the user is corrected based on this (# 25).
[0081]
According to the present embodiment, even when there is a large amount of information (news) to be distributed, urgent information can be immediately distributed without changing the setting. The number of duplicate information distributions can be reduced. Furthermore, by controlling not to send information to the invalid e-mail address 81a, the number of received error information 74 can be reduced, and the burden on the information distribution system 1 can be reduced. Therefore, a person who establishes a BBS can efficiently and easily distribute even large information to each user participating in the BBS.
[0082]
In the present embodiment, the information distribution system 1 is used to operate a BBS in which school students, parents, teachers, and the like exchange information (exchange of news), but in order to operate a BBS of another organization. It can also be used.
[0083]
For example, it may be used for a BBS of an association of which a railway company customer is a member. In this case, a BBS that exchanges regional information for each route, a BBS related to the railway company, or a BBS that notifies emergency information such as operation status may be provided.
[0084]
By using the information distribution system 1 for a plurality of organizations, efficient use of resources can be achieved. In this case, information such as an individual user information table TL1 (see FIG. 3) and a group information table TL2 (see FIG. 4) and a website (portal site) are provided for each group. Thereby, it seems to the user that each organization opens an independent BBS.
[0085]
You may make it determine the priority which distributes an electronic mail according to a day of the week or a time slot | zone. For example, “1” to “3” shown in the priority information 84b (see FIG. 11) are “emergency delivery”, “delivery within 3 hours”, and “delivery by 6 am the next day”, respectively. Define it.
[0086]
In such a case, jobs A, B, and C whose priority information 84b is “1”, “2”, and “3” are stored in the queue storage unit 1D3 and the current time is from 3:00 am If it is within the range of 6 o'clock in the morning, processing (delivery of the e-mail M1) will be performed in the order of jobs A, C, and B. In other time zones, processing is performed in the order of jobs A, B, and C.
[0087]
In addition, the configuration of the entire information distribution system 1 or each part, the processing content, the processing order, the timing for executing the processing, the contents of each database or table, the screen configuration, the method of determining the priority, etc. are appropriately determined in accordance with the spirit of the present invention Can be changed.
