Description

  The present invention relates to a technique for evaluating whether posting of posted data is possible.

  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 of such a system is an electronic bulletin board system. A contributor of the electronic bulletin board system transmits post data to a server connected via a network. The server posts posted data electronically. The user of the electronic bulletin board system 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.

  However, if the content of the posted data is inappropriate for electronic posting, the publicity of the electronic bulletin board system is impaired. For example, content that slanders others, content that does not conform to the purpose of the bulletin board, and advertising content.

Conventionally, for example, an administrator of an electronic bulletin board system has checked the content of posted data. If the content of the posted data is inappropriate for electronic posting, the administrator manually deleted the posted data from the server.
Alternatively, a system has been devised that rejects electronic publication when post data includes an inappropriate keyword that is defined in advance (see, for example, Patent Document 1 and Patent Document 2). .
Hereinafter, post data deemed inappropriate for electronic posting is particularly referred to as “bad post data”. In addition, post data that is appropriate for electronic posting is particularly referred to as “conforming post data”.

If the manager must be responsible for the suitability of the posted data posted electronically, the management burden of the electronic bulletin board system becomes large.
In the first place, the suitability of the posted data should be determined by the subject or target user group targeted by the electronic bulletin board system. Even if the posting data includes an inappropriate keyword, it is too early to determine that the posting data is defective posting data. Similarly, even if the posting data does not include an inappropriate keyword, it cannot be said that the posting data is the matching posting data.

  The present invention has been made in view of such a situation, and a main object thereof is to provide a technique for suitably evaluating whether posting of posted data is possible.

One embodiment of the present invention is a posted data evaluation apparatus.
This device transfers the received posted data to an external evaluation device for evaluating the degree to which posted data to be evaluated is suitable for electronic posting. This apparatus determines whether electronic publication is possible according to the evaluation result returned from the evaluation apparatus.
When the evaluation result indicates that the suitability of electronic posting should be determined by the evaluator, the suitability of electronic posting is determined according to the instruction input from the evaluator.

  According to this aspect, the degree to which the posted data is suitable for electronic posting is determined by the external evaluation device. Moreover, the opportunity for the evaluator to determine the suitability of electronic posting is secured as necessary. Therefore, it becomes easier to determine the content of the posted data more precisely while reducing the check burden on the administrator.

  It should be noted that any combination of the above-described components and a representation of the present invention by a method, apparatus, system, recording medium, and computer program are also effective as an aspect of the present invention.

  According to the present invention, it is possible to provide a technique for suitably evaluating whether posting of posted data is possible.

FIG. 1 is a hardware configuration diagram of an electronic bulletin board system.
The electronic bulletin board server 100 provides a service to a plurality of terminals (hereinafter simply referred to as “client terminal 300”) such as the client terminal 300a and the client terminal 300b connected via the Internet 12. The electronic bulletin board server 100 is also connected to the external evaluation apparatus 200 via the Internet 12. The electronic bulletin board server 100 and the external evaluation device 200 may be connected by a dedicated line.

The electronic bulletin board server 100 electronically posts post data received from each client terminal 300. The client terminal 300 can browse the contents of posted data posted electronically. In this way, post data information is shared among a plurality of client terminals 300. The electronic bulletin board server 100 has a function of determining whether the content of the received posting data is content suitable for electronic posting. The electronic bulletin board server 100 may cause the external evaluation device 200 to determine whether the content of the posted data is suitable for electronic posting. In this case, the electronic bulletin board server 100 once transmits the posting data to the external evaluation device 200 and receives evaluation information indicating the determination result from the external evaluation device 200. The external evaluation device 200 may be a neutral evaluation organization. The external evaluation device 200 may mechanically determine whether the posted data is suitable for electronic posting by software. Alternatively, the user of the external evaluation device 200 may visually check the content of the posted data and determine the degree of suitability for posting. In this way, the electronic bulletin board server 100 electronically posts only the compatible posting data.
A main object of the present invention is to provide a technique for suitably evaluating whether posting of posted data is possible. Hereinafter, the electronic bulletin board server 100 according to the present embodiment will be described with a focus on the posting possibility determination method.

FIG. 2 is a functional block diagram of the electronic bulletin board server.
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. Accordingly, those skilled in the art will understand that these functional blocks can be realized in various forms by a combination of hardware and software. The same applies to the functional block diagrams of FIGS. 3 and 9 to be described later.
Here, functions to be exhibited by each functional block will be mainly described, and specific actions will be described with reference to FIG.

The electronic bulletin board server 100 includes a user interface processing unit 110, a communication processing unit 120, a data processing unit 130, and a data storage unit 150.
The user interface processing unit 110 is in charge of processing related to the entire user interface such as input processing from the user and information display for the user. The communication processing unit 120 is in charge of communication processing with the external evaluation device 200 and the client terminal 300.

The data processing unit 130 executes various types of data processing based on data acquired from the user interface processing unit 110 and the communication processing unit 120. The data processing unit 130 also serves as an interface among the user interface processing unit 110, the communication processing unit 120, and the data storage unit 150.
The data storage unit 150 stores various setting data prepared in advance and data received from the data processing unit 130.

The user interface processing unit 110 includes an input unit 112 and a display unit 114. The input unit 112 receives an input operation from the user. The display unit 114 displays various information to the user.
The communication processing unit 120 includes a client terminal communication unit 122 and an external evaluation device communication unit 124. The client terminal communication unit 122 is in charge of communication processing with each client terminal 300. The external evaluation device communication unit 124 is in charge of communication processing with the external evaluation device 200.

The data storage unit 150 includes a posting data storage unit 152, an evaluation setting data storage unit 154, and a posting status storage unit 156.
Post data storage unit 152 stores post data received by client terminal communication unit 122 from client terminal 300. With respect to the posting data once stored in the posting data storage unit 152, the data processing unit 130 determines whether or not electronic posting is possible. The evaluation setting data storage unit 154 stores determination setting information indicating conditions for determining whether posting of posted data is possible. The data structure of the evaluation setting data storage unit 154 will be described in detail with reference to FIG. The posting status storage unit 156 stores posting status information indicating a processing state for each posting data such as whether the posting is being evaluated or being posted. The data structure of the posting status storage unit 156 will be described in detail with reference to FIG.

The data processing unit 130 includes a posted data evaluation unit 132, a posting control unit 134, an evaluation means selection unit 136, a sub-determination unit 138, an external evaluation apparatus instruction unit 140, and a setting change unit 142.
The setting change unit 142 changes the determination setting information in the evaluation setting data storage unit 154. A user of the electronic bulletin board server 100 inputs a setting change via the input unit 112. The setting change unit 142 changes the contents of the evaluation setting data storage unit 154 according to the input contents. The posted data evaluation unit 132 determines whether the posted data is suitable for electronic posting. The post data evaluation unit 132 will be further described in detail with reference to FIG. The external evaluation apparatus instructing unit 140 is in charge of control for causing the external evaluation apparatus 200 to evaluate whether or not the posting data is electronically published. The external evaluation apparatus instruction unit 140 will be described in detail with reference to FIG. Hereinafter, the determination of whether or not electronic posting is permitted by the posted data evaluation unit 132 is referred to as “internal determination”, and the determination of whether or not electronic posting is permitted by the external evaluation apparatus instruction unit 140 is referred to as “external determination”.

  The evaluation means selection unit 136 selects either internal determination or external determination according to the user setting. The evaluation means selection unit 136 instructs the posting data evaluation unit 132 or the external evaluation apparatus instruction unit 140 to determine whether or not to post posting data according to the selection destination. The evaluation means selection unit 136 may select internal determination or external determination according to the processing load of the posted data evaluation unit 132. Alternatively, the evaluation means selection unit 136 may select internal determination or external determination according to a predetermined selection condition such as the type of post data and the client terminal 300 of the transmission source. The evaluation means selection unit 136 also serves as an interface for the posted data evaluation unit 132, the external evaluation device instruction unit 140, and the sub-determination unit 138.

The sub-determination unit 138 determines whether electronic posting is possible or not by an instruction input from the user when the electronic posting permission / inhibition is not determined by internal determination or external determination. Hereinafter, in order to distinguish from the determination by the sub determination unit 138, the internal determination and the external determination are collectively referred to as “main determination”, and the determination by the sub determination unit 138 is also referred to as “sub determination”. The posting control unit 134 reads post data permitted to be electronically posted from the posted data storage unit 152 and makes it electronically posted by the main determination and the sub-determination. On the other hand, if not permitted, the defective post data is deleted from the post data storage unit 152. When it is finally determined whether or not electronic posting is possible by the main determination or the sub-determination, the client terminal communication unit 122 indicates to the client terminal 300 that is the transmission source of the posted data that electronic posting is started or rejected. Send information. Also, the posting data evaluation unit 132, the sub-determination unit 138, the external evaluation device instruction unit 140, and the posting control unit 134 update the posting status information in the posting status storage unit 156 as appropriate when the posting status of the posting data changes. To do.
Hereinafter, after describing mainly the internal determination, the external determination will also be described.

FIG. 3 is a functional block diagram of the posted data evaluation unit.
The post data evaluation unit 132 includes a first rank specifying unit 160, a first main determination unit 162, an evaluation value calculation unit 164, and a link information acquisition unit 166. Post data evaluation unit 132 performs internal determination.
The evaluation value calculation unit 164 acquires post data to be evaluated from the post data storage unit 152 and calculates a conformity evaluation value. The conformity evaluation value is an index of the degree to which posted data is suitable for electronic posting in the range of 0-100. The larger the conformity evaluation value, the higher the possibility that it is conformity posting data. A method for calculating the conformity evaluation value will be described later.

The posted data may include a URL (Uniform Resource Locator). When link information indicating the position of a document file existing in such another server is included in the posted data, the link information acquisition unit 166 acquires the link destination document file via the communication processing unit 120. The evaluation value calculation unit 164 calculates a conformity evaluation value using not only the content of the posted data but also the content of the linked document file as an evaluation target.
The posted data often includes link information for inducing a viewer to a specific site for advertising purposes. According to such a method, not only post data directly targeted for electronic posting but also a document file substantially targeted for electronic posting can be evaluated. Therefore, it becomes easier to determine the suitability of electronic posting more effectively.
The data processing unit 130 may accumulate link information included in post data for which electronic posting has been rejected in the past as unauthorized link destination information. If the link information included in the posted data corresponds to the illegal link destination information, the evaluation value calculation unit 164 may set the conformity evaluation value as 0 points. According to such an aspect, it becomes easy to prevent that the link information with respect to the website unsuitable for electronic publication is published.

  The first rank specifying unit 160 ranks the posted data according to the conformity evaluation value calculated by the evaluation value calculating unit 164. The rank is a permission rank that is a rank that should be permitted to be electronically posted, a prohibited rank that is a rank that should be prohibited, and a determination-needed rank that is a rank by which a user as an administrator of the electronic bulletin board server 100 should determine whether or not electronic posting is allowed. There are three types. The rank is defined in the determination setting information of the evaluation setting data storage unit 154. For example, in the determination setting information, the relationship between the rank and the conformity evaluation value is defined such that when the conformity evaluation value is 70 points or more, it is classified into a permission rank. The first rank specifying unit 160 specifies the rank of the posted data from the determination setting information based on the conformity evaluation value.

The first main determination unit 162 sends a control command to each functional block according to the specified rank.
a) In the case of permission rank The first main determination unit 162 instructs the posting control unit 134 to electronically post the posted data. The posting control unit 134 reads out the corresponding posting data from the posting data storage unit 152 and electronically posts it. The posting control unit 134 updates the posting status information in the posting status storage unit 156. The client terminal communication unit 122 notifies the posting source of the posting data that it has been electronically posted.
b) In case of prohibited rank The first main determination unit 162 instructs the posting control unit 134 not to post posting data. The posting control unit 134 deletes the corresponding posted data from the posted data storage unit 152. The posting control unit 134 updates the posting status information in the posting status storage unit 156. The client terminal communication unit 122 notifies the sender of the posted data that electronic posting has been rejected.
c) In the case of required determination rank The first main determination unit 162 instructs the sub determination unit 138 to execute the sub determination via the evaluation means selection unit 136. The display unit 114 displays a screen that prompts the administrator to display post data and determine whether or not electronic publication is possible. If the determination by the administrator is affirmative, the sub-determination unit 138 instructs the insertion control unit 134 to perform electronic posting as shown in a). Other processes associated with electronic posting are basically the same. If the determination by the administrator is negative, the posting control unit 134 is instructed not to post as shown in b). The other processes associated with the electronic posting refusal are basically the same.

Next, the calculation principle of the conformity evaluation value will be described. The evaluation value calculation unit 164 evaluates the degree to which the content of the posted data is suitable for electronic posting by so-called natural language processing. Various methods have been proposed for natural language processing. Among them, the principles of the word weight method and the Bayesian filter method, which are considered to be representative, will be briefly described.
Here, an example of a sentence to be inspected is “Pachinko lovers are opposed to the opinion that they want to avoid pachinko and ten thousand betting tickets in TV dramas for the healthy development of young people.” The text to be inspected is “Youth / No / Healthy / Nurturing / For / Television / Drama / In / Pachinko / Ya / Manga ticket / No / Song / Has / I want to avoid / Opinions / To / / Pachinko / lovers / has / against / does. ”Is broken down into 25 words.

1. Word Weighting Method This is a technique for calculating a score as a whole sentence from a score for each word contained in a sentence with reference to a score setting table that defines a score for each word.
In the score setting table, a score is defined for each word, such as “Pachinko: 2 points”, “Odds: 1 point”, and “Every horse ticket: 4 points”. This score is a score indicating a degree of incompatibility with electronic publication. In this score setting table, gambling terms are defined as words that are not suitable for electronic posting. The word “ten thousand betting tickets” has a higher score because it is more inappropriate than the words “pachinko” and “odds”. The score may be set in advance by the administrator of the electronic bulletin board system 10.

As words of the sentence to be inspected, two “pachinko” and one “ten thousand betting ticket” are included. The total score is 8 points by 2 points × 2 + 4 points × 1. When the total score / total number of words is calculated, an index value of 0.32 is calculated by 8/25. The index value of 0.32 is, so to speak, a numerical value indicating a degree inappropriate for electronic posting. Let this index value be x. A conformity evaluation value is calculated by normalizing x within a range of 0 to 100 points, where x is a numerical value indicating an appropriate degree for electronic posting. As an example, if x is a numerical value in the range of 0-10,
Conformity evaluation value = (10−x) × 10
By doing, a conformity evaluation value can be calculated in the range of 0-100.

  In addition to gambling-related terms, score setting tables may be prepared according to categories, such as violent terms and alcohol-related terms. In this way, a numerical value obtained by indexing the degree of suitability for electronic publication as seen from each evaluation axis is called a specific evaluation value. The conformity evaluation value for the entire posted data may be calculated by executing a calculation using a predetermined evaluation function using these specific evaluation values as variables. According to such an aspect, it is possible to determine whether or not electronic publication is possible as viewed from a plurality of evaluation axes. The same applies to the following Bayesian filter method. The evaluation function here will also be described with reference to FIG.

2. Bayesian filter method Prepares a large number of sentence examples that belong to the category of interest and a sentence example that does not belong, and calculates the score as a whole sentence by evaluating the words included in the inspected sentence according to the appearance frequency of the words in each sentence example It is a technique.

  For example, with respect to the evaluation axis of gambling, a large number of sentence examples not related to gambling examples are prepared. A sentence example that matches the evaluation axis like the former is called a “conforming sentence example”, and a sentence example that doesn't fit the evaluation axis like the latter is called a “non-conforming sentence example”. Assuming that there are 100 conforming sentence examples and non-conforming sentence examples, respectively, the word “pachinko” appears 98 times in the conforming sentence example and twice in the non-conforming sentence example. At this time, the sentence including the word “pachinko” is estimated to be a gambling sentence with a probability of 98% and a non-gambling sentence with a probability of 2%.

Thus, the probability that the sentence containing the word is a gambling sentence is calculated about various words. Temporarily, “Pachinko: 98%”, “Odds: 95%”, “Manga ticket: 90%”, “Youth: 20%”, “Healthy: 1%”, “Nurture: 2%”. The sentence to be inspected previously includes five words of “pachinko”, “ten thousand betting tickets”, “youth”, “sound”, and “nurturing”.
The composite probability is (0.98 × 0.90 × 0.20 × 0.01 × 0.02) ÷ {(0.98 × 0.90 × 0.20 × 0.01 × 0.02) + ( 1−0.98) × (1−0.90) × (1−0.20) × (1−0.01) × (1−0.02)} ≈2.2%. The composite probability of 2.2% is also a numerical value indicating a degree inappropriate for electronic publication. Let this synthesis probability be y. A conformity evaluation value is calculated by normalizing y within a range of 0 to 100 points as a numerical value indicating a degree appropriate for electronic posting. As an example,
Conformity evaluation value = 100−y
By doing, a conformity evaluation value can be calculated in the range of 0-100. Here, the description is made on the assumption that the number of appearances of words in the examined sentence is not considered.

  Here, a case is shown in which the conformity evaluation value is calculated using gambling related sentence examples. In addition, a collection of sentence examples of conforming sentence examples and non-conforming sentence examples may be prepared according to categories, such as violent terms and alcohol-related terms. And a conformity evaluation value may be computed from the specific evaluation value calculated about these sentence examples.

  The word weighting method is a method of adding scores of inappropriate words. In the Bayesian filter method, not only inappropriate words but also appropriate words are subject to score calculation. The evaluation value calculation unit 164 calculates a conformity evaluation value by natural language processing represented by such a word weighting method and a Bayesian filter method. The evaluation value calculation unit 164 may calculate a final evaluation value by calculating a matching evaluation value using both the word weighting method and the Bayesian filter method, and performing a predetermined calculation based on the calculation value. For example, the fitness evaluation values calculated by both the word weight method and the Bayesian filter method may be weighted and averaged to obtain the final fitness evaluation value.

FIG. 4 is a data structure diagram of the posting status storage unit.
The posting status storage unit 156 stores posting status information indicating the processing status of the posted data. The contributor ID column 170 indicates a contributor ID for identifying each contributor. The contributor ID may be the handle name of the contributor, or may be substituted with the IP address of the client terminal 300 used by the contributor. The posted date / time column 172 indicates the received date / time of the posted data. The post data ID column 174 indicates a post data ID for identifying each post data. The posted data ID is an ID that is uniquely assigned when the client terminal communication unit 122 receives the posted data. The posting status column 176 indicates the processing status of each posted data.

  In the figure, for example, post data with post data ID “0001” (hereinafter simply referred to as “post data (0001)”) is being electronically posted according to the post status column 176. Posting data (0002) is rejected from electronic posting as a result of internal determination by posting data evaluation unit 132. The posting control unit 134 deletes the posting data (0002) from the posting data storage unit 152 without electronic posting. In addition, the client terminal communication unit 122 transmits information indicating that the posting is rejected to the client terminal 300 that is the transmission source of the posted data (0002).

Posting data (0003) is rejected from being electronically posted as a result of external determination by the external evaluation apparatus instruction unit 140. The posting control unit 134 deletes the posting data (0003) from the posting data storage unit 152 without electronic posting. The client terminal communication unit 122 transmits information indicating that the posting is rejected to the client terminal 300 that is the transmission source of the posted data (0003).
Posting data (0005) is rejected from electronic posting as a result of the sub-determination by the sub-determination unit 138.

  Posting data (0006), posting data (0007), and posting data (0008) are being determined as to whether or not electronic posting is possible. When the posted data is received, the client terminal communication unit 122 transmits standby information indicating that posting is being determined to the transmission source client terminal 300.

The client terminal communication unit 122 may not newly receive post data from the waiting client terminal 300. Thereby, even if a large amount of post data is continuously sent from the specific client terminal 300, the processing load of the electronic bulletin board server 100 can be prevented from becoming excessively high.
Further, from the contributor with the contributor ID “002” who transmitted the defective post data (0002), the client terminal communication unit 122 newly posts until a predetermined non-acceptance period elapses after it is determined that the posting is not performed. Data may not be received. According to such an aspect, it is possible to prevent an increase in processing load on the electronic bulletin board server 100 due to continuous transmission of defective post data from the client terminal 300 that has sent the defective post data. In addition, for a poster, when posting data that electronic posting is rejected is sent to the electronic bulletin board server 100, a penalty of such an unacceptable period is imposed. can do.

FIG. 5 is a data structure diagram of the evaluation setting data storage unit.
The evaluation setting data storage unit 154 stores determination setting information regarding the calculation method of the conformity evaluation value and the ranking method. The evaluation setting data storage unit 154 stores a plurality of types of determination setting information. The user can register or change the determination setting information from the input unit 112 via the setting change unit 142.

  The setting column 180 shows a setting ID for identifying determination setting information. When the determination setting information is newly registered, the setting change unit 142 uniquely assigns a setting ID to the determination setting information. The rank A column 182 indicates a range of conformity evaluation values in the permission rank (hereinafter referred to as “rank A”). The rank B column 184 indicates a range of conformity evaluation values in the determination required rank (hereinafter referred to as “rank B”). The rank C column 186 indicates a range of conformity evaluation values in the prohibited rank (hereinafter referred to as “rank C”). The element column 188 shows an evaluation variable to be considered for calculating the conformity evaluation value. The evaluation function column 190 shows a calculation formula for the conformity evaluation value. The user can select one of these multiple settings.

In the figure, in the determination setting information with the setting ID “01”, if the conformity evaluation value is in the range of 60 to 100, the first rank specifying unit 160 of the posting data evaluation unit 132 determines the posting data as rank A. If the conformity evaluation value is in the range of 30 to 59, the posted data is determined to be rank B, and if it is in the range of 0 to 29, it is determined to be rank C. According to the element column 188 and the evaluation function column 190, the conformity evaluation value is calculated from a plurality of evaluation axes indicating whether the conformity evaluation value is violent, slanderous, or gambling expression. For example, with the Bayesian filter method, the specific evaluation value A, respectively, from three evaluation axes such as violent expression, expression that slanders others, or expression that suggests gambling, respectively. B and C are calculated. And according to the evaluation function shown in the evaluation function column 190,
Conformity evaluation value = A × 0.1 + B × 0.6 + C × 0.3
As a result, the conformity evaluation value is calculated.

In the determination setting information of the setting ID “02”, specific evaluation values A and B are calculated from two evaluation axes, which are adult expression or advertisement expression. Then, according to the evaluation function shown in the evaluation function column 190, the larger one of the specific evaluation values A and B becomes the conformity evaluation value as it is.
In addition, in the determination setting information of the setting ID “03”, the specific evaluation value for the adult expression becomes the conformity evaluation value as it is.

In addition, the conformity evaluation value may be calculated based on whether or not the posting data is in line with the purpose of the electronic bulletin board. For example, when information regarding children's clothing is exchanged in the electronic bulletin board system 10 and post data that does not match the purpose is received, it may be determined as defective post data. Alternatively, only posted data with high information transferability may be targeted for electronic posting by checking a sentence structure of the posted data, for example, a grammatical relationship such as a subject or predicate relationship.
In this way, specific evaluation values and conformity evaluation values can be calculated from various evaluation axes.

  Here, the rank is described as having three levels A to C, but the number of ranks is not limited to three. For example, it may be a two-stage rank setting in which rank A is a required rank and rank B is a prohibited rank. Alternatively, it may be a two-stage rank setting in which rank A is a permission rank and rank B is a determination required rank.

  Further, whether or not electronic publication is possible may be determined by all of internal determination, external determination, and sub-determination. For example, an internal determination is performed to classify it into one of rank A to rank C. Rank A is a permission rank, and rank C is a prohibition rank. Rank B is a rank at which external determination should be performed. As a result of the external determination, rank B is subdivided into rank B1, rank B2, and rank B3. Rank B1 is an electronic posting permission, rank B3 is a rank corresponding to electronic posting refusal, and rank B2 is a rank on which a sub-determination is to be executed. In this way, the content of the posted data can be more objectively checked by making the plurality of determination methods multistage.

The user of the electronic bulletin board server 100 validates any determination setting information in the evaluation setting data storage unit 154. Based on the validated determination setting information, the data processing unit 130 determines whether or not each posting data can be electronically posted. Alternatively, the determination setting information to be used for each contributor may be changed. For example, strict determination setting information may be applied to a contributor who frequently transmits defective post data.
According to the electronic bulletin board server 100 in the present embodiment, the suitability of posting posting data can be calculated as the degree of conformity evaluation value, so the posting permission setting of posting data can be flexibly changed. Further, since the user can also define a calculation formula for the conformity evaluation value, an evaluation method corresponding to the operation of the electronic bulletin board system 10 can be realized.

FIG. 6 is a flowchart showing a process for determining whether or not electronic publication is possible based on internal determination.
First, the client terminal communication unit 122 receives post data from the client terminal 300 (S10). The client terminal communication unit 122 transmits the standby information to the transmission source client terminal 300 (S12). Thereafter, the client terminal communication unit 122 does not receive new post data from the client terminal 300 until the electronic posting permission / inhibition is determined. The evaluation means selection unit 136 instructs the posted data evaluation unit 132 to execute internal determination (S14). In S14, the posted data evaluation unit 132 identifies the rank of the posted data. Details of the processing of S14 will be described in detail with reference to FIG.

  If it is rank A (Y in S16), the posting control unit 134 posts posted data electronically (S18). The client terminal communication unit 122 notifies the client terminal 300 that is the transmission source of the posted data that the posted data has been electronically posted (S20). Thereafter, the client terminal communication unit 122 can receive new post data from the client terminal 300.

  If it is rank B (Y in S22), the first main determination unit 162 instructs the sub determination unit 138 to execute the sub determination via the evaluation means selection unit 136. The sub-determination process will be described in detail with reference to FIG. The posting control unit 134 may post posted data electronically according to the result of the sub-determination. Alternatively, the posting control unit 134 may temporarily post the posting data of rank B, and then stop the electronic posting according to the result of the sub-determination. If it is not rank B, that is, if it is rank C (N in S22), the client terminal communication unit 122 transmits to the client terminal 300 that electronic posting has been rejected (S26). The posting control unit 134 deletes the posted data from the posted data storage unit 152. An unacceptable period may be set for the client terminal 300 for which electronic posting has been rejected, and new post data may not be received until the period has elapsed.

FIG. 7 is a flowchart showing in detail the internal determination process in S14 of FIG.
First, the evaluation value calculation unit 164 determines whether link information is included in the posted data (S50). If it is included (Y in S50), the link information acquisition unit 166 acquires a link destination document file (S52). The evaluation value calculation unit 164 calculates conformity evaluation values for the posted data or the posted data and the linked document file according to the determination setting information in the evaluation setting data storage unit 154 (S54). The first rank specifying unit 160 specifies the rank according to the conformity evaluation value (S56).

FIG. 8 is a flowchart showing the process of the sub-determination process.
When classified into the rank B, the display unit 114 displays a screen prompting the user as an administrator to make a determination. The user browses the posting data classified as rank B and inputs the suitability for electronic posting (S30). When it is input that posting is possible (Y in S32), the sub-determination unit 138 instructs the posting control unit 134 to post the posted data. The posting control unit 134 posts posted data electronically (S34). The client terminal communication unit 122 notifies the client terminal 300 that is the transmission source of the posted data that the electronic posting has been made (S36). On the other hand, when the information indicating that the posting is impossible is input in S32 (N in S32), the client terminal communication unit 122 notifies the client terminal 300 that the posting is rejected (S38).
As a modification, when classified into rank B, the first main determination unit 162 may cause the placement control unit 134 to execute electronic placement. The first main determination unit 162 may cause the sub determination unit 138 to execute the sub determination process shown in FIG. Then, when it is input that the posting is impossible in S32, the sub-determination unit 138 may instruct the posting control unit 134 to stop the posting.
Next, the electronic bulletin board server 100 will be described focusing on external determination.

FIG. 9 is a functional block diagram of the external evaluation apparatus instruction unit.
The external evaluation apparatus instruction unit 140 includes an evaluation value acquisition unit 202, a transfer instruction unit 204, a second rank specifying unit 206, a second main determination unit 208, and a time management unit 210.
At the time of external determination, the transfer instruction unit 204 instructs the external evaluation device communication unit 124 to transmit post data to the external evaluation device 200. At this time, the time management unit 210 measures an elapsed time after the posting data is transmitted to the external evaluation device 200. The external evaluation device 200 calculates a conformity evaluation value for the transmitted post data. Evaluation information including a conformity evaluation value is returned from the external evaluation device 200. The evaluation value acquisition unit 202 acquires this conformity evaluation value via the external evaluation device communication unit 124.

  The second rank specifying unit 206 specifies the rank of the posted data according to the conformity evaluation value acquired by the evaluation value acquiring unit 202. In FIG. 5, the data structure of the evaluation setting data storage unit 154 is shown as the determination setting information for the internal determination, but this is the same for the external determination. The second rank specifying unit 206 determines a rank according to the conformity evaluation value based on the selected determination setting information. The transfer instruction unit 204 may transmit information about the evaluation axis and the evaluation function indicated as the element column 188 and the evaluation function column 190 of the evaluation setting data storage unit 154 to the external evaluation apparatus 200. And the external evaluation apparatus 200 may calculate a conformity evaluation value based on the information about these evaluation axes and evaluation functions. Alternatively, the external evaluation device 200 may calculate the conformity evaluation value by an original evaluation method. In this case, the information shown in the element column 188 and the evaluation function column 190 is not required for the external determination.

When the elapsed time measured by the time management unit 210 exceeds a predetermined time (hereinafter referred to as “external standby time”), the second rank specifying unit 206 regards the posted data as being classified into a predetermined rank. In this embodiment, if the evaluation information is not received even after the external standby time has elapsed, it is handled as being classified into rank B.
The second main determination unit 208 performs post processing and sub determination processing on the posting control unit 134 and the sub determination unit 138 via the evaluation means selection unit 136 according to the rank specified by the second rank specifying unit 206. Instruct execution.

FIG. 10 is a flowchart showing a process for determining whether or not electronic publication is possible based on external determination.
The client terminal communication unit 122 receives post data from the client terminal 300 (S10). As described above, during the non-acceptance period, the client terminal communication unit 122 may discard the posted data as it is without being used as a determination target. When receiving post data, the client terminal communication unit 122 transmits standby information to the client terminal 300 (S12).

  When instructed to execute external determination from the evaluation means selection unit 136, the transfer instruction unit 204 instructs the external evaluation device communication unit 124 to transmit post data to the external evaluation device 200 (S40). At this time, the time management unit 210 measures the elapsed time after the transfer (S42). When the evaluation information is received within the external standby time, the second rank specifying unit 206 specifies the rank of the posted data according to the conformity evaluation value (S45). If it is rank A (Y of S46), the 2nd main judgment part 208 will instruct | indicate the publication control part 134, and will perform electronic publication. The posting control unit 134 posts posted data electronically (S48). The client terminal communication unit 122 notifies the client terminal 300 that the posted data has been posted electronically (S50).

  When the rank is C (N in S46, N in S52), the second main determination unit 208 instructs the posting control unit 134 not to post. The client terminal communication unit 122 notifies the client terminal 300 that electronic posting has been rejected (S54). The posting control unit 134 deletes the posted data from the posted data storage unit 152. If rank B is satisfied (Y in S52), or evaluation information is not received within the external standby time (N in S44), the second main determination unit 208 performs sub-determination to the sub-determination unit 138. (S56). The sub-determination process is the same as that described with reference to FIG.

According to the electronic bulletin board server 100 shown in the present embodiment, the sub-determination is executed for the posted data that cannot be determined whether or not the posting is possible even by the main determination. Therefore, the administrator of the electronic bulletin board server 100 does not need to check all the posted data. In addition, whether or not electronic posting is binary is not determined by the main determination, but is sub-determined as a check by the administrator as necessary, so that the content of the posted data can be checked more flexibly. In other words, an electronic bulletin board system that takes into account both the accuracy and speed of evaluation because it is possible to secure a judgment opportunity by the administrator for post data that is difficult to judge while achieving speeding up of the evaluation process by the main judgment. 10 can be provided.
In addition, by determining the rank according to the conformity evaluation value, the electronic bulletin board server 100 can flexibly set and change the determination condition for electronic posting suitability. Thereby, the convenience of the electronic bulletin board server 100 can be improved.

In the internal determination, the content of the posted data can be determined more precisely by natural language processing as shown in the word weight method or Bayesian filter method. At this time, since the internal determination is performed in consideration of the link information of the posted data, it is further easier to prevent information that is not suitable for electronic posting.
Moreover, since the electronic bulletin board server 100 determines the suitability of electronic posting of posted data from a plurality of evaluation axes, the electronic bulletin board server 100 can flexibly set determination conditions according to the subject of the electronic bulletin board system 10.

  In the case of the external determination, there is an advantage that the processing load required for the main determination of the electronic bulletin board server 100 can be reduced. The evaluation means selection unit 136 may select the external determination when the load of the internal determination process is high. In this case, the processing load required for the main determination of the electronic bulletin board server 100 can be suitably distributed between the electronic bulletin board server 100 and the external evaluation device 200. Further, if the main determination is executed only as an external determination, there is an advantage that the configuration of the electronic bulletin board server 100 can be simplified.

  In the present embodiment, the external evaluation apparatus 200 transmits the conformity evaluation value to the electronic bulletin board server 100. However, the external evaluation apparatus 200 may transmit the rank itself as evaluation information. In such a case, the processing load on the electronic bulletin board server 100 is further reduced. In the external determination, when the evaluation information from the external evaluation device 200 is not received within the external standby time, it is automatically classified into a predetermined rank. Therefore, even if it takes time for external determination of posted data, the main determination process can be handled so as not to be excessively delayed.

  The client terminal 300 that has transmitted the posted data may not receive new posted data until the evaluation of the posted data is completed. Thereby, even if there is a client terminal 300 that mechanically transmits post data continuously, the damage can be prevented in advance. Further, by providing a non-acceptance period, it is possible to effectively exclude unauthorized posters.

  In the present embodiment, the function of the electronic bulletin board server 100 in the electronic bulletin board system 10 has been described. However, the application range of the present invention is not limited to the electronic bulletin board system 10. For example, the present invention can be widely applied to an information sharing system via a network such as a blog system, a mailing list, a news system, a system for managing pages for registering link information, and a system for managing auction listings.
