The communication control device 18 receives a document requesting posting on a predetermined bulletin board from these various electronic devices. The document to be received includes various types of data such as bitmap data in addition to various types of documents such as a text format and an HTML format. Input / output I / F19
Is an interface for connecting various devices such as a speaker for outputting voice, music and the like.

The operation of the activation support processing by the electronic bulletin board system of the present embodiment configured as described above will be described.
This will be described with reference to FIGS. CPU of control unit 11
111 executes the activation support processing described below at predetermined time intervals such as weekly, biweekly, monthly, bimonthly, semiannual, annually, and the like.

FIG. 6 is a flowchart showing the main operation of the activation support processing. The CPU 111 controls each bulletin board G
Is set to j = 1, and a counter k to specify a document in the bulletin board is set to k = 1 (step 11).

Then, the CPU 111 acquires the history of the bulletin board Gj from the access history database 165, and judges the use state of the bulletin board Gj (step 1).
2). Judgment of the usage state is a judgment to distinguish between three states: an active bulletin board, an inactive bulletin board, and a normal bulletin board.
The judgment is made as follows. First, the total number P of the documents posted on the bulletin board Gj within a predetermined period T1 (for example, one month) is calculated from the posting date column (see FIG. 4) of the access history database 165 retroactively from the date on which the processing is performed. . In addition, the total number p of accesses to all documents included in the number P within a predetermined period T2 (for example, one month) from the processing date is stored in the access history database 1.
Obtained from 65 access record fields. P ≧ Q or p ≧
The bulletin board G that satisfies any of the conditions q times is determined to be an active bulletin board, and the bulletin board G that satisfies any of the conditions of P ≦ R or p ≦ r times is determined to be an inactive bulletin board. The bulletin board that does not exist is determined to be a normal bulletin board.

The CPU 111 determines that the usage status of the bulletin board Gj is a normal bulletin board (step 13;
N), because it is neither a link target nor a linked target, the counter j is counted up (j = j + 1) and the counter k is initialized (k = 1) to determine the use state of the next bulletin board (step 1). 14) Return to step 12.

On the other hand, when the bulletin board Gj is active or inactive (step 13; Y), the CPU 111 stores the document Ajk in the document vector database 166 of the storage device 16.
It is checked whether or not the document vector Bjk is stored (step 15). If it is stored (; Y), the document vector Bjk is read (step 16; document vector acquisition means). If the document vector Bjk of the document Ajk is not stored in the document vector database 166 (step 15; N), a document vector Bjk is created (step 17; document vector acquisition means).

FIG. 7 is a flowchart showing the operation of the document vector creation processing. The CPU 111 extracts independent words from the target document A by performing morphological analysis (step 131), and extracts candidate words (phrases) including noun phrases, compound noun phrases, and the like from the target document A, and performs predetermined operations of the RAM 113. It is stored in the area (step 132). Then, the degree of importance f (x) of each candidate word (phrase) is determined from the frequency of appearance of the extracted candidate word (phrase) in the target document A and the evaluation function (step 133). Here, as the evaluation function, for example, when a predetermined important word is specified in advance, weighting for the important word, weighting according to the type of a candidate word (phrase) such as a word, a noun phrase, a compound noun phrase, and the like are used. used. Further C
The PU 111 determines the keywords a, b,... Of the target document A from the value of the determined importance f (x) (step 13).
4). Then, the document vector B = (f (a), f (b),...) Is stored in the document vector database 166 of the storage device 16 using the importance f (x) of each keyword as an element (step 135). It returns to the activation support processing routine of FIG.

The CPU 111 checks whether or not the bulletin board Gj is active based on the result of the determination in step 13 (step 18). If the bulletin board is active (; Y), the document vector Bjk created in step 17 or step 16
Is stored in the active document vector storage area 1132 of the RAM 113 as the document vector of the active document (link candidate document) (step 19). On the other hand, if it is an inactive bulletin board (; N), the inactive document vector storage area 1131 uses the document vector Bjk as the document vector of the inactive document (link candidate document).
(Step 20).

Thereafter, the CPU 111 determines whether or not the value of the counter k is the maximum value (k = max = P) (step 2).
1) If the value is not the maximum value (N), the counter k is incremented (k = k + 1) (step 22), and the document vector of another document Ajk posted on the bulletin board Gj is stored in the RAM 16. Step 15 for
Return to On the other hand, when the value of the counter k is the maximum value (step 21; Y), the CPU 111 determines whether or not the value of the counter j is the maximum value (max), that is, the usage status has been determined for all bulletin boards. It is confirmed whether or not the value is not the maximum value (step 22). If the value is not the maximum value (step 22; N), the process proceeds to step 14 to initialize the count-up counter k of the counter j, and then to
To perform the process for the next bulletin board Gj.

When the value of the counter j is the maximum value (step 23), the CPU 111 stores one document vector B in the inactive document vector storage area 1131 of the RAM 16.
jk is read out (step 24), the similarity S to each active document vector stored in the active document vector storage area 1132 is calculated by a cosine depending on the angle between the two document vectors, and the similarity storage area 1 of the RAM 113 is calculated.
133 (step 25). Now, it is assumed that the angle between the document vector Bx of the document Ax and the document vector By of the document Ay is θ, the inner product of both document vectors is Bx · By, and the magnitudes of both document vectors are | Bx | and | B, respectively.
When y |, the similarity S between the two document vectors is obtained by the following equation (1).

[0029]

## EQU1 ## Similarity S = COS (θ) = (Bx · By) /
(| Bx | × | By |)

The value of the similarity S takes a value of -1.ltoreq.S.ltoreq.1, and as the value is closer to 1, the two document vectors are closer to each other, and it is considered that the two documents Ax and Ay are similar to each other. be able to.

When the similarity S between the document vector of the inactive document read in step 24 and the document vector of each active document is determined, the CPU 111 determines that the similarity S is equal to or greater than a predetermined threshold (for example, 0.8). A certain active document A is listed (step 26). Then, the information of the inactive document is displayed on the bulletin board of the similar active document as the related document (step 27).

The CPU 111 checks whether or not there is an unprocessed inactive document vector regarding the calculation of the similarity.
If the document vector exists (step 28; Y), the process returns to step 24, and the process for the unprocessed document vector is repeated. If there is no unprocessed inactive document vector (step 28; N), the activation support processing according to the present embodiment ends.

FIG. 8 conceptually shows the similarity between two documents with respect to each document Ajk shown in FIG.
The document vector Bjk shown in this figure is two-dimensionally displayed in order to facilitate conceptual understanding, but in reality, the number of elements of each document vector (in the case of one document vector), or The number of the union of the elements of the two document vectors (in the case of similarity calculation) is the dimension. In the title box in the horizontal direction of FIG. 8, all the documents A21 and A22 posted on the bulletin board G2 determined to be inactive in step 13 are displayed.
And document vectors B21 and B22 obtained in steps 16 and 17 for each document. In the title column in the vertical axis direction, all the documents A11, A12, A13 posted on the bulletin boards G1 and G3 determined to be active,
, A31, ..., and document vectors B11, B12, B13, ..., B31, ... acquired for each document are displayed. Then, the document vector B of the inactive document A11
21 and respective document vectors B11, B22,... Of the active document.
Is determined that the inactive document A21 and the active document 13 are similar. Similarly, it is determined that the inactive document A22 and the active document A31 are similar.

When the active documents A13 and A31 similar to the inactive documents A21 and A22 are found, the information of the inactive document A21 is displayed in the active document A13 column of the active bulletin board G1.
Inactive document A2 is displayed in the active document column A13 of the active bulletin board G3.
2 is displayed. As shown in FIG. 2, the association between the active document and the inactive document is made by the document A of the active bulletin board G1.
Inactive document A determined to be similar to 13 titles
The title 21 is clearly indicated as a related document (grayed, lighter than usual, surrounded by a dotted line, etc.) and displayed.

As shown in FIG. 2, active bulletin boards G1, G
3, the inactive documents A21 and A22 are displayed in association with each other, so that there is a high possibility that a user who accesses the bulletin board G1 or G3 refers to the inactive documents A21 and A22, and the inactive bulletin board G2 is activated. Is supported.
Also, the user of the electronic bulletin board can use the related displayed inactive document to support idea generation and to find a new agenda (thread).

In order for the user to access an inactive document displayed in association with the active document, for example, A21 in FIG. 2, a method of accessing the inactive document A21 via the inactive bulletin board G2, and an active document in the active bulletin board G1 There is a method of accessing by selecting (clicking) the inactive document A21 displayed in association with A13. In the latter case, access is performed from a bulletin board other than the bulletin board on which the inactive document is actually posted. Therefore, when the inactive document A21 is selected, an access approval flow for asking the user who posted the inactive document A21 to access from another bulletin board is started, and the inactive document A2 is activated.
After the approval of the first user, the access is enabled.

In FIG. 2, inactive document documents A21, A22
The active documents similar to are described in a case where each active document is one by one. However, a plurality of active documents may be similar to one inactive document. In this case, in the present embodiment, all active documents are associated with each other. If there are more than a predetermined number of similar active documents (for example, 11 or more), the top 10 active documents with a higher similarity S are displayed. May be associated with. Conversely, a plurality of inactive documents may be associated with one active document. In this case, all inactive documents may be associated with each other.
The association may be limited to a predetermined number (for example, five) of inactive documents. In the latter case as well, a predetermined number of inactive documents having a high similarity S are selected, but the similarity S with the inactive documents associated with other active documents is weighted, for example, by 0.8. , The similarity S to an inactive document that is not associated with another active document
The weight is 1.1.

FIG. 2 shows active documents A11 and A31.
9 shows a state in which the inactive documents A21 and A22 are related to each other. As shown in FIG. 9, the inactive document A21 is related to the active document A21, and the inactive document A22 is related to the active document A31. You may make it. Further, a hyperlink to a similar inactive document may be automatically added to a title appearing on the document list screen of the active bulletin board or a term in the active document.

The configuration and activation support processing of the present embodiment have been described above. However, the present invention is not limited to each of these embodiments, and various modifications are possible within the scope of the invention described in each claim. Deformation is possible. For example, in the embodiment, a document posted on an active bulletin board is defined as an active document, and a document posted on an inactive bulletin board is defined as an inactive document.
In the present invention, it is also possible to determine whether each document is active or inactive, regardless of whether the entire bulletin board is active or inactive. In this case, whether each document is active or inactive is determined based on the number of accesses to the document. For example, a document in which the number of accesses in one month is q 'or more is defined as an active document, and a document in which the number of accesses is r' or less is defined as an inactive document.

Further, in the embodiment, the document vectors of both documents are used to determine an active document similar to the inactive document. However, the present invention is not limited to the method using the document vector, and other known methods are used. Various methods described above may be used to check and determine the similarity between the two documents.

In the embodiment described above, the case where an inactive document is associated with an active document or a bulletin board has been described. However, in the present invention, the reverse may be applied. That is, an active document may be associated with an inactive document or a bulletin board. As a result, not only the inactive document but also many similar documents are posted on the inactive side (document or bulletin board), thereby increasing the degree of attention and consequently being activated. By associating a similar document with an inactive document or the like as a cherry tree, the document is accessed through apparent activation (dead trees are also busy with mountains), and as a result, it is actually activated. In this sense, a similar document to be associated with an inactive side may be similar to an inactive document, and is not necessarily an active document.

The embodiments described above are not limited to documents created in Japanese, but can be applied to documents created in any language. In this case, it is only necessary to change a portion that does not affect the configuration of the present invention, such as using a morphological analysis algorithm for the language in which the target document is created.

Note that, in the above embodiment,
For each device, each unit, each operation, each process, and the like, the embodiment can be configured by each unit (up to a unit) as a general concept including them. For example, “CPU11
1. Calculate the similarity S with each active document vector by cosine depending on the angle between the two document vectors (step 25). "Similarity calculation means"
And "Similarity S is a predetermined threshold (for example, 0.8)
The active document A is listed up (step 2)
6). "May be configured as" active document listing means ". Similarly, the embodiment may be configured with a higher concept such as “「 (operation) means ”for various other operations.
