Description

  The present invention relates to a technique for electronically publishing posted data, and more particularly, to a technique for determining whether or not to publish posted data.

  In recent years, with the spread of computers and the advancement of network technology, the exchange of electronic information via the network has become popular. An example is an electronic bulletin board system. In an electronic bulletin board system, a user transmits post data from a client terminal to a server. The server posts posted data electronically. Another user can check the posted data posted electronically on the client terminal. The electronic bulletin board system is widely used as an effective tool for information sharing among a plurality of persons. Hereinafter, a user group for exchanging information in a predetermined electronic bulletin board system is referred to as “community”.

As an example of community management, there is a site that publishes the impression of a product purchaser. A user who purchases a product transmits post data describing the impression of the product to the site. The site will collect post data for various products. By accessing such a site, a user uses so-called word-of-mouth information obtained from the same consumer's standpoint as a judgment material when purchasing a product. Word-of-mouth information is often the decisive factor in purchasing decisions. In addition, such a community also has the effect of encouraging large-scale enterprises that provide products to have solidarity with weak consumers.

  On the other hand, if the content of the posted data is inappropriate for electronic posting, the reliability of the electronic bulletin board system is impaired. For example, content that does not conform to the purpose of the bulletin board, disguised disguise as a weak person, exaggerated information and false information hinder the sound management of the community. A malicious user may acquire a plurality of user IDs by himself and behave as if there are many tuned persons in his speech. A community that can easily obtain a user ID by acquiring a user ID tends to attract a malicious user.

On the other hand, recently, a community management method using a social networking site (SNS) has been attracting attention. In order to participate in SNS, introduction by existing members and registration of e-mail addresses are required. SNS prevents a malicious user from entering by requesting a certain amount of personal information at the time of registration while maintaining a certain level of anonymity. However, ordinary users may feel psychological resistance to providing personal information to the site.
Thus, there is a trade-off that a community with high anonymity easily attracts malicious users and a community with low anonymity increases psychological resistance to participation.

  The present invention has been made in view of the above-described problems, and a main object thereof is to provide a technique for realizing community management that is easy to participate and easily obtain useful information.

One embodiment of the present invention relates to a post processing apparatus that electronically publishes post data received from a client terminal to other client terminals. In the present embodiment, “post data” includes not only data transmitted to the post processing device by the user but also data transmitted to the post processing device by the administrator of the post processing device. In the following description, for the sake of convenience, description will be made assuming post data transmitted by the user.
This apparatus receives and accumulates post data from many users, and also receives data indicating content evaluation on post data of another user by one user. The evaluation tendency for each user is made into a database, and the closeness of evaluation tendency between users is quantified.
When this device tries to display post data α on a client terminal of a certain user A, it determines how the user B who has a similar evaluation tendency as the user A evaluates the post data α, and the evaluation Depending on the content, the display method of the post data α for the user A may be determined.
Moreover, you may receive the data which show the evaluation with respect to another user of a certain user from a client terminal. And you may make a database of mutual evaluation between users. When posting data α is to be displayed on the user A's client terminal, it is determined how the user B who has a similar evaluation tendency to the content of the posting data as the user A is evaluating the poster C of the posting data α. Then, the display method of the post data α for the user A may be determined according to the evaluation content.

  According to the present invention, there is an effect in realizing community management that facilitates participation and easy acquisition of useful information.

FIG. 1 is a hardware configuration diagram of the posting system 10.
The electronic bulletin board server 100 is connected to a plurality of terminals (hereinafter simply referred to as “client terminal 200”) such as the client terminal 200a and the client terminal 200b via the Internet 12. The electronic bulletin board server 100 is a device that receives posted data from each client terminal 200 and electronically posts it. When requested by the client terminal 200a, the electronic bulletin board server 100 transmits post data received from the client terminal 200b to the client terminal 200a. The content of the posted data transmitted from the client terminal 200b can be confirmed on the client terminal 200a. In this way, post data information is shared among a plurality of client terminals 200.

FIG. 2 is a schematic diagram for explaining an outline of processing of the posting system 10.
Here, it is assumed that users of the posting system 10 are a user A, a user B, and a user C. Each user accesses the electronic bulletin board server 100 via the client terminal 200. When the user views the posting data held in the electronic bulletin board server 100, the user transmits an evaluation for the content of the posting data to the electronic bulletin board server 100. Here, it is assumed that user A, user B, and user C have already evaluated the contents of various post data. As a result, it is assumed that user A and user B have a similar evaluation tendency with respect to the posted data, and user A and user C have different evaluation tendencies.

  In the situation shown in the figure, the user B and the user C have already browsed the post data α, and are evaluating each of the post data α. User B positively evaluates post data α, and user C negatively evaluates post data α. User A has not yet viewed the posting data α, and of course has not input any evaluation for the posting data α.

  Here, when the user A tries to browse the posted data α, the display method of the posted data α on the client terminal 200 used by the user A depends on the user B who has a similar evaluation tendency to the user A. Since the user B positively evaluates the posted data α, the posted data α is preferentially displayed by a method such as displaying it larger than other posted data. By determining the display method according to the evaluation of the posted data of the user whose evaluation tendency is similar to that of the user, that is, the values are close to each other, the user who uses the posting system 10 can choose from among the many posted data. It is possible to quickly reach useful post data. If the user B negatively evaluates the posted data α, the display priority of the posted data α on the user A's client terminal 200 is lowered. For example, it is displayed in a small size, grayed out or hidden. This is because the post data α is highly likely not to be sympathetic information for the user A as long as the user B who has a close evaluation tendency to the user A has not made a positive evaluation.

According to such a processing method, when the user A acquires post data from the electronic bulletin board server 100, the post data suitable for the interest and hobby of the user A can be preferentially displayed. Thereby, the user A can easily find information useful for the user A from a large amount of post data stored in the electronic bulletin board server 100. On the other hand, the users A, B, and C are actually evaluating the posted data and need not provide any personal information to the electronic bulletin board server 100. More preferably, the user A takes measures so that information such as who the evaluation tendency is similar to that of the user A or how the user B or the user C is evaluating each posted data cannot be acquired. It is desirable. By taking such a measure, it becomes easy to conceal even information related to each user's interests and hobbies.
Although the description has been made centering on the evaluation regarding the contents of the posted data, the posted data display method may be determined in addition to the evaluation of the user or others with respect to the poster itself.

FIG. 3 is a functional block diagram of the electronic bulletin board server 100.
Each block shown here can be realized in hardware by an element such as a CPU of a computer or a mechanical device, and in software it is realized by a computer program or the like. Draw functional blocks. Therefore, those skilled in the art will understand that these functional blocks can be realized in various forms by a combination of hardware and software.
Here, functions to be exhibited by each functional block will be mainly described, and specific actions will be described later.

  The electronic bulletin board server 100 includes a communication processing unit 300, a data processing unit 400, and a data holding unit 500. The communication processing unit 300 is in charge of processing related to the entire user interface, such as input processing from the user and information display to the user. The data processing unit 400 executes various data processing based on data acquired from the communication processing unit 300 or the data holding unit 500. The data processing unit 400 also serves as an interface between the communication processing unit 300 and the data holding unit 500.

  The posted data transmission / reception unit 310 transmits / receives posted data to / from the client terminal. Post data transmission / reception unit 310 includes a post data transmission unit 312 and a post data reception unit 314. Post data transmission unit 312 accepts a post data acquisition request from a user and transmits the post data to client terminal 200 of the user. Post data receiving unit 314 receives post data from the user.

  The evaluation receiving unit 320 receives information indicating the content of the posted data and the evaluation of the poster from each user. The evaluation receiving unit 320 includes a content evaluation receiving unit 322 and a contributor evaluation receiving unit 324. The content evaluation receiving unit 322 receives content evaluation data (hereinafter referred to as “content evaluation data”) for the content of the posted data from the user. The contributor evaluation receiving unit 324 receives contributor evaluation data (hereinafter referred to as “contributor evaluation data”) from the user.

  When a post data acquisition request is made from the user, the display method determination unit 420 determines a display method of post data to be acquired based on various data stored in the data storage unit 500. The display designation unit 330 transmits display designation data indicating the display method determined by the display method determination unit 420 to the client terminal 200.

  The question handling unit 340 transmits question data to the user and obtains answer data from the user. When the user wishes to use the posting system 10, the question answering unit 340 is used when registering with the electronic bulletin board server 100 or when the user logs in to the electronic bulletin board server 100 when starting the use of the posting system 10. Asks the user a question. If the user does not answer this question correctly, the user is not registered in the electronic bulletin board server 100 and cannot log in.

  The question handling unit 340 includes a question data transmission unit 342 and an answer data reception unit 344. The question data transmission unit 342 transmits the question data to the client terminal 200. The answer data receiving unit 344 receives user answer data for these questions. The user is categorized into one of four types of groups I to IV according to the contents of the answer to this question. Details will be described in detail with reference to FIGS.

  The user's post data is evaluated by inputting a predetermined plurality of items. For example, the user's own value is selected from the options set for each item, such as whether the opinion written in the post data is “agree” or “disagree”, and whether the opinion level is “high” or “low”. Choose the option that suits your view. The user can set new items in addition to the previously set items. The evaluation item receiving unit 350 receives data indicating the contents of the new item from the client terminal 200 when the user adds a new item. Items and options, addition of new items, and the like will be described in detail with reference to FIGS.

  Content evaluation data and contributor evaluation data of each user are accumulated in the content evaluation tendency holding unit 510 and the contributor evaluation tendency holding unit 520. The evaluation change / test unit 360 transmits / receives data to / from the client terminal 200 when the user temporarily changes these accumulated data or temporarily evaluates the contents of the posted data and the poster.

The evaluation change / test unit 360 includes a content evaluation request receiving unit 362, a content evaluation transmitting unit 364, a changed content evaluation receiving unit 366, a temporary evaluation receiving unit 368, a contributor evaluation request receiving unit 370, a contributor evaluation transmitting unit 372, and a change. A poster evaluation receiving unit 374 is included.
The content evaluation request receiving unit 362 receives from the client terminal 200 an acquisition request for content evaluation data held in the content evaluation tendency holding unit 510. The content evaluation transmission unit 364 transmits the content evaluation data requested for acquisition to the client terminal 200. The user can also change the content evaluation data. As will be described in detail later, the user can acquire and update his / her past content evaluation data. The change content evaluation receiving unit 366 receives the content evaluation data after the temporary change.

  The contributor evaluation request receiving unit 370 accepts a request for acquiring contributor evaluation data held in the contributor evaluation tendency holding unit 520 from the client terminal 200. The contributor evaluation transmission unit 372 transmits the contributor evaluation data requested for acquisition to the client terminal 200. The user can temporarily change his / her past poster evaluation data. The change contributor evaluation receiving unit 374 receives the contributor evaluation data after the temporary change.

  In addition to this, the user can also make a temporary evaluation before definitely evaluating the content of the posting data and the poster. With such provisional evaluation, the user can confirm how the display content changes. For example, when post data α and post data β are both displayed on the screen and the post data α is evaluated, the display method of the post data β may change depending on the evaluation content. With the provisional evaluation, for example, the user can try “how does the display method of the posted data β change if the opinion of the posted data α is agreed with the provisional evaluation”. The temporary evaluation receiving unit 368 receives data indicating such temporary evaluation.

  The posting data display method is selected from a plurality of display methods. Although details will be described with reference to FIG. 4 in the following, in the present embodiment, the number of “star marks” displayed on the left side of the posted data changes according to the display priority. For example, five star marks are displayed beside posted data with the highest display priority, and the posted data with the lowest display priority is not displayed. The display priority of the posted data is quantified by the display method determination unit 420 of the data processing unit 400. The display method determination unit 420 determines a display method by comparing the display priority with a preset threshold value. For example, when the display priority is 90 or more, five star marks are used, and when the display priority is 80 or more and less than 90, four star marks are used.

  The user can freely set a display priority threshold at which the number of star marks changes. The threshold is set for each user. The threshold transmission / reception unit 378 is in charge of data transmission and reception for the user to change the threshold. The threshold transmission / reception unit 378 includes a threshold request reception unit 380, a threshold transmission unit 382, and a change threshold reception unit 384. The threshold request receiving unit 380 receives a threshold acquisition request from the client terminal 200. The threshold transmission unit 382 transmits threshold data indicating the requested threshold. When receiving the threshold data from the threshold transmission unit 382, the user changes the threshold data and transmits the changed threshold data to the electronic bulletin board server 100. The change threshold receiving unit 384 receives the changed threshold data from the client terminal 200.

  Post data display methods include "how a user who has a similar evaluation tendency to himself evaluates the content of the posted data" and "how the user evaluates the poster of the posted data" Determined based on various factors. Each of these elements is digitized, and the final display priority is determined according to the importance of each element. The user can freely set a coefficient for determining this weighting. The coefficient is set for each user. The coefficient transmission / reception unit 386 is in charge of data transmission / reception for the user to change the coefficient.

  The coefficient transmission / reception unit 386 includes a coefficient request reception unit 388, a coefficient transmission unit 390, and a change coefficient reception unit 392. The coefficient request receiving unit 388 receives a coefficient acquisition request from the client terminal 200. The coefficient transmission unit 390 transmits coefficient data indicating the requested coefficient. When receiving the coefficient data, the user changes the coefficient data and transmits the changed coefficient data to the electronic bulletin board server 100. The change coefficient receiving unit 392 receives the changed coefficient data from the client terminal 200.

  The posted data is displayed by any one of a total of six display methods from 1 to 5 star marks and non-display. Of these, the user can request acquisition of only posted data displayed by the designated display method, such as “posted data with three star marks” and “hidden posted data”. For example, the user can acquire only post data that is treated as non-display, and can confirm whether such post data is actually post data that is not in his / her interest or hobby.

  The designated display posting transmission / reception unit 394 is in charge of data transmission / reception when the user designates posting data to be acquired by a display method. The designated display posting transmission / reception unit 394 includes a designated display posting request receiving unit 396 and a designated display posting transmitting unit 398. The designated display posting request receiving unit 396 receives a posting data acquisition request corresponding to the display method designated by the user. The designated display posting transmission unit 398 transmits post data corresponding to the designated display method.

  The data processing unit 400 includes a similar user selection unit 410, a display method determination unit 420, a user registration / determination unit 430, an automatic evaluation unit 440, an evaluation item registration unit 450, an evaluation change / test processing unit 460, and a coefficient change processing unit 470. Including.

  The similar user selection unit 410 detects a similar relationship between users according to the content evaluation data. For example, when the user A is to be investigated, a user who becomes content evaluation data close to the content evaluation data for the user A of the content evaluation tendency holding unit 510 is detected. A specific processing method will be described in detail with reference to FIG.

  The display method determination unit 420 determines the display method of each post data for each user. The display method determination unit 420 includes the content evaluation data of the content evaluation tendency holding unit 510, the poster evaluation data of the contributor evaluation tendency holding unit 520, the content suiting value of the content suiting value holding unit 540, and the contributor evaluation value holding unit 550. A display method for posting data is determined based on a poster evaluation value or the like. The content conforming value is a numerical value obtained by indexing whether the content of the posted data conforms to a predetermined evaluation standard. For example, the content conforming value of post data including words that are contrary to public order and morals is a low value. As a method of calculating the content adaptation value, for example, a known natural language processing technique such as a Bayesian filter used in a spam filter or the like may be applied. The poster evaluation value is a numerical value obtained by indexing the degree to which the poster provides useful information. When posting data having a low content conforming value is transmitted, the poster evaluation value of the poster decreases.

  The user registration / determination unit 430 executes processing related to user registration with the electronic bulletin board server 100 and user typification. The user registration / determination unit 430 includes a user classification processing unit 432 and a user registration determination unit 434. The user classification processing unit 432 classifies users into a plurality of groups according to the answers received by the answer data receiving unit 344 from the users. The user registration determination unit 434 determines whether or not to permit the use of the posting system 10 according to the answer received from the user by the answer data receiving unit 344.

The automatic evaluation unit 440 calculates the content conforming value and the poster evaluation value described above. The automatic evaluation unit 440 includes a content conforming value calculation unit 442 and a contributor evaluation value calculation unit 444. The content conforming value calculation unit 442 calculates whether the content of the posted data received by the posted data receiving unit 314 is suitable for electronic disclosure as a content conforming value. The contributor evaluation value calculation unit 444 calculates a contributor evaluation value, which is an evaluation value for the contributor who created the posting data, from the content conforming value of the posting data received by the posting data reception unit 314.
Evaluation item registration unit 450 registers a new evaluation item accepted by evaluation item receiving unit 350.

  The user can temporarily change the content evaluation data and the poster evaluation data. It is also possible to temporarily evaluate the content of the posting data and the poster. When the temporarily changed content evaluation data and the poster evaluation data are received, the evaluation change / test processing unit 460 transfers these data to the similar user selection unit 410 and the display method determination unit 420, and these temporary change data The user is selected and the display method is redetermined based on the above. When the contents of the posted data and the data for provisional evaluation of the poster are received, these data are transferred to the similar user selection unit 410 and the display method determination unit 420, and the selection and display of the user are performed based on the temporary evaluation data. The method is redetermined. If there is an instruction from the user, the evaluation change / test processing unit 460 definitively reflects these temporary data on the content evaluation trend holding unit 510 and the poster evaluation trend holding unit 520.

  The coefficient change processing unit 470 holds the changed coefficient data received by the change coefficient receiving unit 392 as a coefficient for determining the display method. The display method determination unit 420 refers to the coefficient held by the coefficient change processing unit 470 and calculates the display priority according to an arithmetic expression described later.

  The data holding unit 500 includes a content evaluation tendency holding unit 510, a poster evaluation tendency holding unit 520, a user classification holding unit 530, a content matching value holding unit 540, and a poster evaluation value holding unit 550. The content evaluation tendency holding unit 510 holds a set of content evaluation data for each user. This set becomes data indicating the tendency of content evaluation for post data for each user. The data structure of the content evaluation tendency holding unit 510 will be described in detail with reference to FIG. The contributor evaluation trend holding unit 520 holds a set of contributor evaluation data for each user. This set becomes data indicating the evaluation tendency for the contributor for each user. The data structure of the poster evaluation tendency holding unit 520 will be described in detail with reference to FIG.

  The user classification holding unit 530 holds the result of the user classification processing unit 432 classifying users into groups I to IV. The group classification and the data structure of the user classification holding unit 530 will be described in detail with reference to FIG. The content conforming value holding unit 540 retains the content conforming value. The data structure of the content conforming value holding unit 540 will be described in detail with reference to FIG. The contributor evaluation value holding unit 550 holds a contributor evaluation value. The data structure of the contributor evaluation value holding unit 550 will be described in detail with reference to FIG.

  Hereinafter, the present invention will be described based on an actual usage example of the posting system 10.

FIG. 4 is a screen diagram of the post data list screen 27 displayed on the client terminal 200 when a certain user A makes a post data acquisition request to the electronic bulletin board server 100.
Each posting data on the posting data list screen 27 displays a list of posting data indicating user's evaluation of a predetermined product for children, for example, a wooden toy “car set”.

  The area 20 in the figure displays post data to which three star marks are assigned. The number of star marks is determined by the display method determination unit 420. The post data to which more star marks are assigned indicates that the post data is recommended for the user A having a higher display priority. In the area 20, two character strings are displayed: “This is very useful!” And “What are your recent children thinking?”. When a title is set in the post data, the title becomes a display character string as it is. When no title is set for the posted data, a predetermined number of characters are extracted from the top of the body of the posted data and become a display character string. It can be seen that two pieces of post data displayed in the area 20 among the post data for the “car set” are particularly recommended post data for the user A.

  The area 22 is an area showing post data to which two star marks are assigned, and a character string “I love my child” is displayed. The area 24 is an area showing the posting data to which one star mark is given, and two character strings “I remembered when I was small” and “What was the news before, but ...” It is displayed. The area 26 is an area showing post data without a star mark, and two character strings “Professional baseball players are very kids…” and “I'm always running around, but now…” It is displayed. Thus, the post data to which more star marks are added, that is, the post data recommended for the user A is displayed higher. The star mark is given in the range of 1 to 5, and posted data with a particularly low display priority is not displayed on the posted data list screen 27.

  Each character string on the posted data list screen 27 is given link information for the posted data display screen 35 for displaying the entire posted data. The user can display a post data display screen 35 as shown in FIG. 5 by clicking a character string with an input device such as a mouse.

FIG. 5 is a screen diagram of the posted data display screen 35.
The post data display screen 35 shown in the figure is displayed on the client terminal 200 when the character string “I love my child” displayed in the area 22 of FIG. 4 is clicked. An area 28 of the posting data display screen 35 shows a contributor who has created posting data. Here, it can be seen that the poster name of the contributor is “Afro”. The handle name is set when the user registers with the electronic bulletin board server 100. The handle name may be appropriately changed according to the user's desire.

  The area 30 shows the title of the posted data. The title is “I love my child”. The title is set when the post data is created, but the title is not a required input item. When no title is input, the area 30 is displayed blank. The area 32 shows the post data body. In the figure, "I think that such a deformable toy is our child ... (omitted) ..." is displayed. When the user A confirms the posted data, the user A evaluates the content of the posted data and the poster. When the user A clicks the evaluation button 34, a post evaluation screen 53 shown in FIG. 6 is displayed.

FIG. 6 is a screen diagram of the posting evaluation screen 53.
The post evaluation screen 53 shown in FIG. 5 is a screen that is displayed when the evaluation button 34 is clicked when the post data display screen 35 is displayed. That is, this is a screen for evaluating the poster “Afro” and the content of the posted data. An area 36 of the posting evaluation screen 53 shows selection items for evaluating a poster. The user inputs the evaluation of the poster “Afro” as the degree of support / non-support from among the five choices.

  The area 40 of the posting evaluation screen 53 is an input area for evaluating the contents of posting data. The content of the posted data is evaluated for three evaluation items. In the area 40, the item 42 is an item for evaluating the approval or disapproval of the opinion described in the post data. The item 44 is an item for evaluating the level of opinion described in the post data. The item 46 is an item for evaluating the logical structure of the opinion described in the post data. There are three choices for item 42: “opinion is in favor”, “opinion is disagreement”, and “opinion is out of opinion”. There are two choices for the item 44: “high level” and “low level”. The item 46 has three options: “Discussion is polite”, “Discussion is violent”, and “Discussion is incoherent”.

  After browsing the posted data, the user inputs the rating for the poster and the rating for the posted content shown on the posted rating screen 53. Among these, the area 36 is an essential input item, but each evaluation item in the area 40 is an arbitrary input item. In the post evaluation screen 53 shown in the figure, as an example of the user evaluation, the user A relatively supports the contributor and selects “agree with opinion” and “discussion is polite” for the post content. We do not evaluate the “level” of posted content. When the OK button 52 is clicked, the evaluation ends, and when the cancel button 49 is clicked, the evaluation is cancelled. When the OK button 52 is clicked, the client terminal 200 transmits the poster evaluation data and the content evaluation data to the electronic bulletin board server 100. When the provisional OK button 51 is clicked, provisional evaluation is input. The provisional evaluation will be described in detail with reference to FIG.

  Although three evaluation items are displayed in the area 40, the user can additionally set an evaluation item. When the item addition button 50 is clicked, an evaluation item setting screen 59 shown in FIG. 7 is displayed.

FIG. 7 is a screen diagram of the evaluation item setting screen 59.
The evaluation item setting screen 59 shown in the figure is a screen that is displayed when the item addition button 50 is clicked while the post evaluation screen 53 is displayed. The area 54 of the evaluation item setting screen 59 is an area for inputting an evaluation item name to be newly added. Here, an evaluation item name “product purchase judgment” is set in order to evaluate whether the information is actually useful for the product purchase decision “car set”. An area 56 shows options for new items. Three options of “useful”, “can't say anything” and “useless” are set. An option requires two or more settings. When the OK button 58 is clicked, the setting of the evaluation item is confirmed. When the cancel button 57 is clicked, the item setting is canceled. The evaluation item set in the evaluation item setting screen 59 is set as a new evaluation item for the posting data of the poster “Afro” shown in the posting data display screen 35 of FIG. When the OK button 58 is clicked, the client terminal 200 transmits data indicating the newly added evaluation item to the electronic bulletin board server 100. The evaluation item receiving unit 350 receives this data, and the evaluation item registration unit 450 holds the evaluation item name set for the post data in association with it. When another user B views the posting data, an item “determination of product purchase” is additionally displayed on the posting evaluation screen 53. Thus, the evaluation item newly added by the user may be set for post data other than the post data of FIG.

FIG. 8 is a data structure diagram of the contributor evaluation tendency holding unit 520.
A, B, and C arranged in the left column from the top to the bottom indicate users on the evaluation side, and A, B, and C arranged in the upper row from the left to the right represent users on the evaluation side. Indicates. According to the figure, the numerical value indicating the evaluation of the user A with respect to the user B is “4”. The evaluation value of user A for user C is “1”. These evaluation values correspond to the evaluation contents in the region 36 in FIG. When the user selects “support”, the evaluation of the user by the user is “5”. When the contributor evaluation receiving unit 324 receives the contributor evaluation data indicating the evaluation “support” from the client terminal 200, the contributor evaluation receiving unit 324 records the evaluation value “5” corresponding to “support” in the contributor evaluation tendency holding unit 520. The evaluation value is reduced by 1 as “support” is approached to “reject”, and the evaluation value when “reject” is selected is “1”. In the case of the figure, it can be seen that the user A does not support the user C as a contributor at all, but the user A relatively supports the user B. Similarly, user B strongly supports user A, but user B does not value user C very much. Since the user C is not so much supported by the user A and the user B as far as seen in the figure, it may not be a good poster.

FIG. 9 is a data structure diagram of the content evaluation tendency holding unit 510.
Here, only data indicating a content evaluation tendency of a certain user A is shown. For other users such as users B and C, a data table similar to that shown in the figure is prepared. “Opinion”, “level”, “discussion”, etc. arranged from top to bottom in the left column indicate item names for the user to evaluate the contents of the posted data. This corresponds to the item name shown in the area 40 of FIG. The evaluation item “determination of product purchase” is an item added by the user A by the input of FIG. [Alpha], [beta], and [gamma] arranged in the upper row from left to right indicate post data.

According to the figure, the evaluation value is “5” for the items “opinion” and “discussion” for the post data α of the user A. On the other hand, the evaluation value for the item “level” is not set. This indicates that user A is not evaluating the level of the posted content. These evaluation values correspond to the evaluation contents on the post evaluation screen 53 of FIG. In the case of three options such as “opinion”, the evaluation value of the left option “agree” in item 42 is “5”, the middle option “opposite” is “3”, and the right option “out of the box” Corresponds to “1”. Thus, when there are two or more options, an evaluation value between 1 and 5 is assigned according to the number of options.
Note that when a new evaluation item “determination of product purchase” is added, a new item is added to the left column in the same manner as the evaluation item set from the beginning in the electronic bulletin board server 100. In FIG. 9, a new item is added to post data β. Since this new item is a new item for post data β, no evaluation value is set for the post data α and post data γ. When the administrator of the electronic bulletin board server 100 adopts and sets it as a normal evaluation item, the newly added item is also displayed in the posted data α and the posted data γ, and evaluation is possible.

  FIG. 10A is a data structure diagram of the content matching value holding unit 540. The upper row shows post data, and the lower row shows the content conforming value of each post data. The content adaptation value calculation unit 442 indexes the degree to which the content of each posted data is suitable for electronic posting, and calculates a content adaptation value. The content conforming value is calculated with 100 points being a perfect score. According to FIG. 10A, the content suitability value of the posted data α is 90 points, the content suitability value of the posted data β is 43 points, and the content suitability value of the posted data γ is 78 points. That is, it can be seen that the post data β is post data not very suitable for electronic posting. For example, it is considered that the posting data includes many terms that violate public order and morals and terms that do not conform to the purpose of the bulletin board. On the other hand, it can be said that the posting data α is posting data that does not include such inappropriate terms. Inappropriate posted data can be automatically specified in advance by mechanical determination by the content matching value calculation unit 442. The display method determination unit 420 may not release posted data whose content conforming value is equal to or less than a predetermined threshold.

  FIG. 10B is a data structure diagram of the contributor evaluation value holding unit 550. The upper line indicates the user, and the lower line indicates the poster evaluation value. The contributor evaluation value is an evaluation value for evaluating whether the contributor is an excellent contributor, and is calculated by the contributor evaluation value calculation unit 444 on a 100-point scale. A user who contributes a lot of post data whose content conforming value is low has a low poster evaluation value. For example, when a certain user transmits three types of post data whose content suitability values are 90 points, 80 points, and 70 points, this user's contributor evaluation value is the average score of three types of content suitability values 80 It is good also as a point. According to FIG.10 (b), the contributor evaluation value of the user A is 95 points, the contributor evaluation value of the user B is 82 points, and the contributor evaluation value of the user C is 31 points. Therefore, it can be seen that user A has posted a relatively large amount of appropriate posting data in line with the purpose of the bulletin board, but user C is a user who tends to post posting data that is inappropriate in terms of content. A malicious user can be automatically specified in advance by mechanical judgment by the poster evaluation value calculation unit 444. The display method determination unit 420 may not publish posted data by a poster whose poster evaluation value is equal to or less than a predetermined threshold.

  FIG. 10C is a data structure diagram of the user classification holding unit 530. The upper row shows user groups, and the lower row shows the user names included in each group. As will be described in detail later, the user needs to answer questions presented at the time of registration or login. Then, according to the contents of the answer, the user classification processing unit 432 classifies the user into any of four groups from I to IV. According to FIG. 10C, user A, user B and user G belong to group I, user D and user F belong to group II, user E belongs to group III, and user C belongs to group IV. . Here, for the sake of simplicity, only seven users A to G are shown, but in actual operation, the number of users may be several hundred to several hundred thousand.

FIG. 11 is a sequence diagram showing the process of user registration processing on the electronic bulletin board server 100.
First, the communication processing unit 300 of the electronic bulletin board server 100 receives registration request data indicating a user registration request from the client terminal 200 (S10). The question data transmission unit 342 transmits the question data to the client terminal 200 that is the transmission source of the registration request data (S12). The question data preferably includes a plurality of alternative questions such as “Do you have an interest in the Winter Olympics” or “Which do you like Western food or Japanese food?”.

  The question data is displayed on the display screen of the client terminal 200. The user answers the question displayed on the answer screen (not shown) (S14). By requiring the user to answer the question, it is possible to prevent a malicious user from registering several different names properly. In other words, only the user who really needs the service of the electronic bulletin board server 100 is registered by letting the user pay the labor cost of answering the question. The question data includes a question whose answer is uniquely determined from general common sense in order to prevent unauthorized registration of the user. For example, there are some types of questions that must clearly answer “No”, such as “Do you think the world population will exceed 100 billion people this year (2006)?” If this type of question is not answered correctly, the user is not registered in the bulletin board server 100. This is a measure for suitably executing user classification based on a question and an answer by preventing registration of a user who answers the question data. Such questions other than the questions that must be correctly answered are questions for classifying the users into groups I to IV. When the user answers the question, answer data indicating the answer content is transmitted from the client terminal 200 (S16). The response data receiving unit 344 of the electronic bulletin board server 100 receives the response data.

  The user registration determination unit 434 refers to the answer data and determines whether the answer to the correct answer question is correct (S18). When an incorrect answer is included (N in S18), the communication processing unit 300 transmits registration result notification data indicating that registration is impossible to the client terminal 200 (S24). If there is no incorrect answer (Y in S18), the user classification processing unit 432 classifies the user who requested registration into groups I to IV according to the contents of the answer data (S20). A user is newly registered in the user classification holding unit 530 according to the classification destination (S22). The communication processing unit 300 transmits registration result notification data indicating completion of registration to the client terminal 200 together with a user ID and a password for identifying the user (S24). In this way, the user is registered in the electronic bulletin board server 100 and is allowed to send and receive post data.

FIG. 12 is a sequence diagram showing a processing process when a registered user logs in to the electronic bulletin board server 100.
First, the communication processing unit 300 of the electronic bulletin board server 100 receives login request data indicating a login request to the electronic bulletin board server 100 from the client terminal 200 (S26). The login request data includes a user ID and a password. If the user ID and password are not those of the registered user, login is not permitted. If the login is valid, the question data transmission unit 342 transmits the question data to the client terminal 200 that is the transmission source of the login request (S28). Thus, even a legitimate user needs to answer the question data again at the time of login. The question data is displayed on the screen of the client terminal 200, and the user answers the question (S30). The reply data receiving unit 344 receives reply data from the client terminal 200 (S32). Based on the answer data, the user classification processing unit 432 reclassifies the users (S34).

  Here, user classification and reclassification will be described. For example, there are three questions to be answered by the user at the time of registration, and the user is classified into any of groups I to IV according to the answer. Note that these three questions are questions for user classification separately from questions that require correct answers. Hereinafter, they are called Question 1, Question 2, and Question 3. Of these three questions, the questions that are actually referred to for classification processing are only two questions, question 2 and question 3 (hereinafter simply referred to as “classification questions”), and the remaining one question 1 (hereinafter simply referred to as “question”). “Ignore questions”) does not affect the classification process. The question is an alternative question. Since the two questions are classified, there are a total of four combinations of the answer patterns. That is, for two questions, the user “Yes / Yes” is group I, the user “Yes / No” is group II, the user “No / Yes” is group III, and the user “No / No” is Classified as Group IV.

  The administrator of the electronic bulletin board server 100 can additionally set questions as appropriate. Then, at the time of login, the user is requested to answer the newly added question. When the question 4 is newly added, the question 1 that is an ignored question is discarded. The newly added question 4 becomes a classification question with incidental conditions. As a result, Question 2, Question 3, and Question 4 remain and the total number of questions remains three. A user who requests registration after the new question 4 is added (hereinafter, simply referred to as “new registered user”) is classified into a group according to the newly added classification question. The newly registered user is required to answer an answer to the new three classification questions at the time of registration. At this stage, they are classified according to question 2 and question 3.

  A user who has been registered before the new question 4 is added (hereinafter simply referred to as “registered user”) answers the question 4 newly added during an arbitrary period set by the administrator. When this period ends, either question 2 or question 3 that has been set as a classification question so far becomes an ignoring question. Here, it is assumed that Question 2 is an ignored question. On the other hand, question 4 which is a newly added classification question with additional conditions is formally a classification question. In this way, the newly registered user and the already registered user are shuffled into one of the four groups in accordance with two questions, question 3 and question 4, which are the classified questions after the change. If the registered user does not answer a new question within the above period, the user is classified into a group V different from I to IV. The evaluation tendency of the user belonging to the group V with respect to the posted data does not affect the process in which the display method determination unit 420 determines the display priority. That is, the similar user selection unit 410 excludes users belonging to the group V from selection targets of “users with similar evaluation tendencies”. However, the user who belongs to the group V is again classified into any of the groups I to IV by answering the newly added classification question.

FIG. 13 is a sequence diagram illustrating a process in which a user browses and evaluates post data.
A user A designates a subject of topic and transmits a posting data browsing request to the electronic bulletin board server 100. For example, the user A selects a topic subject such as a toy “car set”. The data processing unit 400 selects post data related to the “car set” from the post data stored in the data holding unit 500 (S36). Although there are a plurality of corresponding posting data as shown in FIG. 4, for the sake of simplicity, the posting data α will be described as an object here. The similar user selection unit 410 determines which group of I to IV the user A who is the browsing request belongs to based on data of the user classification holding unit 530 (S38). Since the user must answer all questions at login, the user is not classified into group V at this stage. According to FIG. 10C, the user A belongs to the group I.

  The similar user selection unit 410 selects a user who has already evaluated the posting data α from the group I to which the user A belongs. Here, it is assumed that both the users B and G belonging to the group I have already evaluated the posting data α. The similar user selection unit 410 selects a user who is close to the evaluation tendency of user A's posted data among the users B and G as a similar user. Here, it is assumed that the user B is selected as being closer than the user G. The display method determination unit 420 refers to the content evaluation trend holding unit 510 and the poster evaluation trend holding unit 520 and detects how the user B evaluated the content of the posting data α and the poster ( S40). The display method determination unit 420 acquires corresponding evaluation values from the content evaluation tendency holding unit 510 and the poster evaluation tendency holding unit 520. Furthermore, the display method determination unit 420 acquires the content conforming value and the poster evaluation value of the posting data α from the content conforming value holding unit 540 and the contributor evaluation value retaining unit 550, and calculates the display priority of the posting data α. . Then, based on the display priority, a display method, specifically, how many star marks are added or whether or not to be displayed is determined (S42). The posted data transmission unit 312 transmits the posted data α to the client terminal 200 (S44). In addition, the display designation unit 330 transmits display designation data for designating the display method to the client terminal 200 (S46).

  The posted data α is displayed on the client terminal 200 by the display method designated by the display designation data (S48). User A who has viewed the posted data α evaluates the content of the posted data and the poster. The content evaluation data indicating the evaluation content and the poster evaluation data are transmitted to the electronic bulletin board server 100. The content evaluation receiving unit 322 of the electronic bulletin board server 100 receives the content evaluation data, and the contributor evaluation receiving unit 324 receives the contributor evaluation data (S50). These evaluation data are recorded in the content evaluation tendency holding unit 510 and the poster evaluation tendency holding unit 520 (S52).

The flow up to the determination of the display method has been briefly described above, but will be specifically described below using numerical values. Here, it is assumed that the user A requests browsing of the unevaluated post data α, and the contributor of the post data α is the user C.
The similar user selection unit 410 refers to the content evaluation tendency holding unit 510 and determines which of the user B and the user G is closer to the evaluation tendency of the user A. For example, it is assumed that the average score when the user A evaluates each item with respect to the posting data β with a maximum score of 5 is 3 points. On the other hand, it is assumed that the average score of the evaluation of the user B with respect to the post data β is 3.5 points, and in the case of the user G, 2 points. In this case, regarding post data β, it can be said that user B is closer to user A's evaluation than user G. Similarly, for other post data such as post data γ, it is determined which of the user B and the user G is closer to the evaluation of the user A. Of the users B and G, the user who has an evaluation tendency close to that of the user A is selected as a similar user of the user A for the plurality of post data. Here, user B is selected as a similar user.

  The display method determination unit 420 refers to the content evaluation tendency holding unit 510 and the poster evaluation tendency holding unit 520, and acquires as a value what kind of evaluation the user B has performed on the post data α. According to the content evaluation tendency holding unit 510, it is assumed that the user B “agrees” for the item “opinion” of the post data α, that is, the evaluation value is 5. Further, it is assumed that the item “discussion” is “careful” for the post data α, that is, the user B has an evaluation value of 5. In addition, it is assumed that the item “level” is not evaluated. Assuming that each item has the same weight, the average value of the evaluation values of each item being evaluated is used as an index value for content evaluation for user B's post data α (hereinafter referred to as “content index value”). Called). In this example, it is “5”.

  According to the contributor evaluation tendency holding unit 520, it can be seen that the evaluation value for the user C of the user B is “2”, and this is the evaluation value for the user C of the user B as it is (hereinafter referred to as “second contributor”). Also called “index value”). Further, the evaluation value of the user A for the user C is “1” (hereinafter also referred to as “first poster index value”). The display priority is calculated from the five variables of the content index value, the first and second poster index values, the content adaptation value, and the poster evaluation value.

  First, the display method determination unit 420 changes the content index value, the first contributor index value, and the second content index value from a maximum score of 5 to a maximum score of 100. Therefore, when these three index values are acquired, the display method determination unit 420 multiplies each index value by 20. In the above example, the content index value is 5 × 20 = 100, 100 points, the first poster index value is 1 × 20 = 20, 20 points, and the second poster index value is 2 × 20 = 40, 40 points. Converted to a point. Further, it can be understood that the content conforming value of the posted data α and the poster evaluation value for the poster of the posted data α are 90 points and 31 points, respectively, according to FIG. 10 (a) and FIG. 10 (b).

  When each variable is not particularly weighted, the average value 56.2 of the above five variables, 100, 20, 40, 90, and 31 is a value indicating the display priority.

  The display method determination unit 420 compares the calculated display priority with a preset threshold value and determines display designation data. In this embodiment, the display priority 90 or higher is 5 stars, 80 or more and less than 90 is 4 stars, 70 or more and less than 80 are 3 stars, 60 or more and less than 70 are 2 stars, 50 or more and less than 60 are 1 star. 40 or more and less than 50 are zero stars, and less than 40 are not displayed. Therefore, when the post data α is displayed on the user A's client terminal, only one star mark is displayed.

  In this embodiment, post data with a display priority of less than 40 is not displayed. However, some users may wish to reduce the total number of posted data to be displayed by further narrowing down the posted data. If the user can freely change the set threshold, it is possible to display useful information more efficiently. For example, if less than 70 is set as non-display, the number of post data displayed on the client terminal 200 is reduced, and the user only needs to view information with a high display priority. This will be described below.

It is assumed that the user displays a plurality of post data on the client terminal 200 as shown in FIG. When the user terminal 200 wants to reduce the number of posted data items displayed, the user requests the electronic bulletin board server 100 to acquire threshold data indicating the threshold value. The threshold request receiving unit 380 receives the acquisition request. The threshold transmission unit 382 transmits threshold data set for the user to the client terminal 200. The client terminal 200 displays the currently set threshold value, and the user can freely change it. The changed threshold data is transmitted from the client terminal 200 to the electronic bulletin board server 100. The change threshold receiving unit 384 receives the changed threshold data and sets the changed threshold for the user. Thereby, the user can adjust the number of post data to be displayed on the client terminal 200.
The threshold value change for non-display has been described above, but other threshold values such as a threshold value for five stars may be changed. Thereby, the user can use the posting system 10 more comfortably.

FIG. 14 is a sequence diagram showing a process when posting posted data to the electronic bulletin board server 100.
First, the user inputs post data to be posted to the client terminal 200 (S54). Post data input from the client terminal 200 is transmitted to the electronic bulletin board server 100 (S56). The posted data receiving unit 314 receives posted data from the client terminal 200 (S56). The content adaptation value calculation unit 442 calculates a content adaptation value by quantifying the degree to which the text of the received post data is suitable for electronic posting, with 100 points being a perfect score (S58). The contributor evaluation value calculation unit 444 calculates the contributor evaluation value by quantifying the contributor's evaluation of the posting data with 100 points as a perfect score based on the calculated content conforming value (S60). The content suiting value is held in the content suiting value holding unit 540. The contributor evaluation value is held in the contributor evaluation value holding unit 550. The following method can be considered as a method for calculating the poster evaluation value.

The poster evaluation value is calculated as an average value of the content conforming values. Suppose that the post data α, β, and γ shown in FIG. According to FIG. 10A, the content evaluation value of each posting data is 90, 43, 78.
(90 + 43 + 78) /3=70.333 ...
It becomes.
When the number of post data to be calculated increases, the influence of one post data on the poster evaluation value is reduced. Therefore, the poster evaluation value of a user who has transmitted a large amount of post data hardly changes. Therefore, a predetermined number may be set as an upper limit for the number of pieces of post data to be verified in order to calculate the contributor evaluation value. For example, only the content conforming values of 20 pieces of post data counted from the latest post data in the order of newest may be targeted. In this case, when the user posts new post data, 20 post data counted from the post data are targeted, and the poster evaluation value is always calculated from the content conforming value of the 20 post data. The Thereby, a contributor evaluation value is calculated from 20 pieces of post data counted from the latest post data in the newest order.

  After the content matching value and the poster evaluation value are calculated, the posted data is stored in the data holding unit 500 of the electronic bulletin board server 100 (S62).

FIG. 15 is a sequence diagram showing a processing process when changing the evaluation contents performed by the user in the past.
The posting system 10 changes the display method according to the content of the posting data and the evaluation of the poster. If the evaluation on the posted data cannot be changed again, the evaluation based on the temporary emotion continues to be reflected in the display method as it is. For example, even if the user A once evaluates a certain piece of post data, there is a case where another evaluation is desired when the same post data is viewed again at a later date. In order to correctly reflect the user's values on the bulletin board server 100, it is desirable that past evaluation contents can be changed afterwards.

  Here, first, it is assumed that a certain post data α is displayed on the client terminal 200 (S64). The post data α may be unevaluated or evaluated. Although the posted data α is interesting, there may be a small number of star marks. In this case, it can be said that the user's values are not well reflected as a display method. In such a case, the user can match his own values with the display method by changing the evaluation data so far.

  When the user desires to change past evaluation data, the user requests past evaluation data from the electronic bulletin board server 100 (S66). Here, it is assumed that both content evaluation data and contributor evaluation data are requested. The content evaluation transmission unit 364 and the contributor evaluation transmission unit 372 transmit the user content evaluation data and the contributor evaluation data to the client terminal 200 (S68). Here, they are collectively referred to simply as “evaluation data”. The evaluation data is displayed on the client terminal 200. The user changes the contents of the evaluation data (S70). The user interface screen at this time may be the same mode as the screen shown in FIG. 6, or the data is displayed in the mode shown in FIG. 8 or FIG. 9, and the user can directly change the numerical value. May be.

  The client terminal 200 transmits the changed evaluation data to the electronic bulletin board server 100. The changed content evaluation receiving unit 366 of the electronic bulletin board server 100 receives the changed content evaluation data, and the changed contributor evaluation receiving unit 374 receives the changed contributor evaluation data (S72). The similar user selection unit 410 selects a similar user based on each evaluation data after the change. The display method determination unit 420 determines the display method based on the changed evaluation data (S74). The display designation unit 330 transmits display designation data indicating the newly determined display method to the client terminal 200 (S76). In response to the display designation data, the client terminal 200 redisplays the posted data (S78). When the user accepts the new display method, the user inputs the confirmation (Y in S80). The electronic bulletin board server 100 is notified of the confirmation, and the changed evaluation data received in S72 is stored as formal evaluation data in the content evaluation trend holding unit 510 or the poster evaluation trend holding unit 520 (S82). If not permitted (N in S80), the changed evaluation data is not officially reflected on the bulletin board server 100 and discarded.

FIG. 16 is a sequence diagram showing a processing process when a user temporarily evaluates certain posted data.
As described with reference to FIG. 15, the user can change the past evaluation contents performed by the user. In addition to this, it is also possible to confirm how the display method changes when provisional evaluation is actually performed on the screen shown in FIG. When the current display method is a comfortable display for the user and it is desired to maintain this situation in the future, it is necessary to carefully evaluate the posted data.

  Here, first, it is assumed that a certain post data α and post data β are displayed on the client terminal 200 (S84). Both post data α and post data β are not evaluated. Although the posted data β is interesting, the number of star marks may be set less, and vice versa. When the user wants to maintain such a display method, the user performs a temporary evaluation to carefully evaluate the content of post data α that has not yet been evaluated. (S86). In the screen diagram 53 of FIG. 6, after each evaluation is input in the area 36 or the like, the temporary evaluation can be performed by clicking the temporary OK button 51. Temporary evaluation data indicating the contents of the temporary evaluation is transmitted from the client terminal 200 to the electronic bulletin board server 100.

  The temporary evaluation receiving unit 368 receives temporary evaluation data from the client terminal 200 (S88). The evaluation change / test processing unit 460 temporarily holds the received temporary evaluation data (S90). The similar user selection unit 410 and the display method determination unit 420 select a similar user based on the temporary evaluation data and determine the display method of the post data α and β (S92). The display designation unit 330 transmits display designation data indicating the determined display method to the client terminal 200 (S94). The client terminal 200 redisplays the posting data α and the posting data β according to the display designation data (S96). Thereby, it is possible to confirm “how the display method of the posted data β changes when the posted data α is provisionally evaluated”. When the display method after the provisional evaluation is acceptable (Y in S98), the user inputs a confirmation, and the electronic bulletin board server 100 is notified to that effect. The temporary evaluation data received in S88 is formally reflected in the content evaluation trend holding unit 510 and the poster evaluation trend holding unit 520 (S100). If not allowed (N in S98), the temporary evaluation data is not officially reflected on the electronic bulletin board server 100 and discarded.

FIG. 17 is a screen diagram of the importance level changing screen 89 for changing the weighting of the evaluation items.
The display method determination unit 420 determines the display priority by considering the content index value, the first poster index value, the second poster index value, the content adaptation value, and the poster evaluation value to the same extent. However, the importance of each of these variables can be customized for each user. The importance level change screen 89 is a screen displayed on the client terminal 200 for that purpose.

  For example, the first poster index value indicating the evaluation of the user's own poster may be emphasized, and the second poster index value indicating the evaluation of the similar user to the poster may not be emphasized. If the user can arbitrarily set and change the importance of each variable, the user can easily select a display method suitable for himself. In region 60, the user changes the weighting of the evaluation for the poster. For example, when it is desired to determine post data based on a person, the weighting ratio of the area 60 can be increased. In the area 60, an area 62 for setting a weight for the user's own evaluation and an area 64 for setting a weight for the other user's evaluation are displayed. The weighting is set in the range of 0 to 1. When the importance is set to the right, the weighting value is 1, and when the importance is set to the left, the weighting value is 0. According to the area 62 in FIG. 5, “self poster evaluation” is emphasized and is set to 0.8. On the other hand, the “external person (similar user) contributor evaluation” in the area 64 is relatively unimportant and is set to 0.5.

  In area 70, the user sets a weight for the posted content. Here, it is also possible to set a weight for each evaluation item of the posted content, and it is also possible to determine how much the evaluation of the posted content is weighted in relation to the evaluation of the poster. In area 74, a weight is set for each evaluation item. In the figure, for the evaluation items “opinion”, “level”, and “discussion”, how much weight is set for each evaluation item in relation to other evaluation items is determined. For example, the value of “opinion” is 0.9, which is very important. The value for “discussion” is 0.7, with a little emphasis. The value of “level” is 0, which means that this item is not used for determining the display method. The content index value is calculated according to these weights. If a similar user A for a certain user views and evaluates the posted data γ, the evaluation value of the item “opinion” of the user A is 3 in the case of FIG. This is multiplied by 0.9 / (0.9 + 0 + 0.7) to obtain 1.6875. Similarly, the evaluation value of the item “discussion” is 5, and is multiplied by 0.7 / (0.9 + 0 + 0.7) to be 2.1875. The evaluation value of “level” is 1, but since the user sets the weight to 0, the value becomes 0 by multiplying by 0 / (0.9 + 0 + 0.7). 3.875 which added all these becomes a content index value.

  In the area 72, weighting of the content index value is set. In FIG. 17, it is set to 0.7. When the display method determining unit 420 determines the display method from the evaluation data acquired from the content evaluation tendency holding unit 510 and the poster evaluation tendency holding unit 520, the “self poster evaluation” in the area 62 and the “others” in the area 64 are displayed. Weighting is performed using the coefficients set in “Poster Evaluation of” and “Evaluation of Posted Content of Others” in the area 72.

  In the area 80, inappropriate post data and a value for automatically identifying a malicious user are set in advance by mechanical judgment. In area 84, the user selects a threshold value for determining a content conforming value calculated from the content of the posted data. In the case of FIG. 17, “post content automatic evaluation” is 50 points or more, and therefore, post data having a content conforming value of less than 50 is not displayed to the user. In the area 82, the user selects a threshold value for determining the poster evaluation value calculated from the content matching value. In the case of FIG. 17, the “poster automatic evaluation” is 70 points or more, and therefore, post data with a poster evaluation value of less than 70 points is not displayed to the user even if the content conforming value is 50 points or more. Display priority is determined in consideration of content index value, first contributor index value, second contributor index value, etc. only for post data whose content conforming value and contributor evaluation value exceed the threshold set by the user. . Content-adapted values and contributor evaluation values may be used as variables for calculating display priority as described above, but as an alternative, these values are used only to determine whether display is possible. It may not be used for the priority calculation. In that case, it will be as follows when it demonstrates using a specific numerical value.

Assume that the user's own evaluation (first poster index value) is “4”, the evaluation of the user C who is a similar user (second poster index value) is “5”, and the similar user C's posting. If the evaluation (content index value) for the content is “3.875”, the display priority calculated for the threshold value comparison by the display method determination unit is as follows when the set values in FIG. 17 are used. .
4 × 20 × 0.8 / (0.8 + 0.5 + 0.7)
+ 5 × 20 × 0.5 / (0.8 + 0.5 + 0.7)
+ 3.875 × 20 × 0.7 / (0.8 + 0.5 + 0.7)
= 84.125

  If there is no problem with the setting shown in FIG. 17, the user clicks an OK button 86 to determine the setting and store it in the coefficient change processing unit 470. If there is a problem, by clicking the cancel button 88, the changed setting is discarded and the conventional setting set in the electronic bulletin board server 100 is maintained.

  When it is desired to change the coefficient for weighting, coefficient acquisition request data is transmitted from the client terminal 200 to the electronic bulletin board server 100. The coefficient request reception unit 388 receives coefficient acquisition request data, and the coefficient transmission unit 390 transmits coefficient data set for the user to the client terminal 200. Then, an importance level change screen 89 is displayed on the client terminal 200 according to the set value, and the user can change each coefficient, that is, the weight. Coefficient data indicating the coefficient after the change is transmitted from the client terminal 200 to the electronic bulletin board server 100. The change coefficient receiving unit 392 receives the changed coefficient data, and the coefficient change processing unit 470 sets the changed coefficient for the user. As described above, the coefficient change processing unit 470 holds coefficient settings for each user.

  Some of the posted data is displayed with a star mark, but there is also posted data that is not displayed because the content conforming value or the like does not exceed the threshold value or the value calculated by the display method determining unit 420 is low even if the threshold value is exceeded. Exists. Even if the posted data display method feels comfortable for the user, it is possible that the posted data that suits his / her interests / hobbies is not displayed. Therefore, it is necessary to browse post data that is not displayed and check whether there is a problem. This will be described below.

  It is assumed that the user displays a plurality of post data on the client terminal 200 as shown in FIG. When browsing the non-displayed post data, the client terminal 200 transmits post request data corresponding to the non-display method to the electronic bulletin board server 100. The designated display posting request receiving unit 396 receives the request data. The display method determination unit 420 acquires post data that is not displayed when the display method is determined from the data holding unit 500 and transmits the post data to the designated display post transmission unit 398. The designated display posting transmission unit 398 transmits non-displayed post data to the client terminal 200, and the user confirms the non-displayed post data. After that, if there is a problem with the posting data that is not displayed, the user can search for a display that is comfortable for him / her by changing the evaluation data or the coefficient as described with reference to FIGS. Can do.

  The present invention has been described above based on the embodiment. The present invention is not limited to this embodiment, and various modifications thereof are also effective as aspects of the present invention. In this embodiment, when determining the posting data display method, the similar user selection unit 410 refers to the content evaluation tendency holding unit 510 to select another user who has a similar evaluation tendency to the user who browses the posting data. ing. This is because a user who has a similar evaluation tendency to the posted content is considered to have close interests and hobbies. On the other hand, since the user who supports the same contributor is also considered to be close in concept, the similar user selection unit 410 refers to the contributor evaluation tendency holding unit 520 and selects a user with a close evaluation tendency with respect to the contributor. The display method may be determined. In addition, when a poster posts posted data to the electronic bulletin board server 100, the poster may be able to input other data accompanying the posted data. For example, when the user A thinks that the content to be posted is confident, the user A transmits input data “confident” together with the posted data to the electronic bulletin board server 100. The electronic bulletin board server 100 stores the post data and input data in the data holding unit 500 in association with each other. When the electronic bulletin board server 100 obtains a request for browsing the posted data from the user B, the posted data and the input data are transmitted as a set, and the requesting client terminal 200 has the user A who is “confident” with the posted content. The input result of is displayed. User B evaluates user A who is a contributor, and contributor evaluation receiving unit 324 receives contributor evaluation data. The contributor evaluation receiving unit 324 stores the contributor evaluation value holding unit 550 as the contributor evaluation data of “user A in a confident state”, not as the contributor evaluation data of “user A”. The user A who does not input anything and the user A who inputs “confident” are treated as different contributors in the evaluation. Thereby, the similar user selection part 410 can select the user whose content of evaluation is closer because the object of evaluation is subdivided.
