And transmits a related keyword display request including the keyword selected by the user to the clipping service providing apparatus (more precisely, including the keyword selected in the keyword list field 121 and received by the clipping service providing apparatus). Send the relevant keyword display request to be processed on the Internet). Then, the computer displays a related keyword window based on information (details will be described later) transmitted from the clipping service providing device in response to the related keyword display request.

By using the search-required keyword input field 124 and the “search” button 125, the service user can determine that a certain word is appropriate as a keyword (an appropriate number of articles are searched). It is a control that allows you to check if there is. Specifically, when there is a word that the user wants to check whether it is appropriate as a keyword, the service user enters the word into the keyword-in-research required input field 124 and then presses the “Survey” button 125. When the “investigation” button 125 is pressed, the computer displaying the clipping setting page transmits a keyword investigation request including the keyword set in the investigation required keyword input field 124 to the clipping service providing apparatus. . And the computer is
Based on the information transmitted by the clipping service providing device in response to the keyword search request, a plurality of types of keywords are displayed in the search result, as in the keyword list field 121 and the related keyword window. Window (details will be described later)
Is displayed.

That is, the clipping service providing apparatus provides three types of items (keyword list column 121, Related keyword window and survey result window; hereinafter, also referred to as keyword presentation items)
Is provided.

The present clipping service providing apparatus displays, as these keyword presentation items, those listing keywords that can be appropriately clipped, and makes their contents timely. Thus, the device is configured as described above. Specifically, the clipping service providing device is configured as follows.

FIG. 2 shows a functional block diagram of the clipping service providing apparatus. As illustrated, the clipping service providing apparatus includes a member information database 11, an article information database 12, a folder definition information database 13, a thesaurus database 14, a ranking index database 15, a folder storage unit 16, and a control unit 17. I have. In addition, this figure and FIGS.
In FIG. 6, there are places where the database is abbreviated as DB and the keyword is abbreviated as KW.

The member information database 11 includes information for personal authentication (member ID and password) and various attribute information (sex, It is a database that stores information input during the procedure of becoming a member, such as age and information on a field of interest, and information indicating whether or not the user is a clipping service user. The clipping service providing apparatus (control unit 17) refers to the member information database 11 to determine whether or not the person who has accessed itself is a service user.

The article information database 12 is a database for collecting a plurality of pieces of article information distributed daily from various businesses.

The folder definition information database 13 stores, for each service user, some folder definition information (folder name, storage days, extraction target designation information, and search condition expression) set by the service user using the clipping setting page. Is stored in the database.

The thesaurus database 14 is a database in which synonyms of various words are stored.

The ranking index database 15 is shown in FIG.
As shown schematically in the figure, the keyword column, the number of setters column,
It has a hit number column, a keyword-only ranking index column, a related keyword column, both keyword setters column, and a related keyword ranking index column. For a certain keyword (a certain word stored in the keyword column), It is a database having a configuration capable of storing several sets of the keyword set numbers and the related keyword ranking indices.
As will be described in detail later, this ranking index database 1
Reference numeral 5 denotes a database whose contents are updated daily. In the clipping service providing apparatus, the contents of the keyword list section 121, the related keyword window, and the survey result window are determined with reference to the ranking index database 15. Is done.

The control unit 17 is a functional block that provides a function of providing a clipping service to the clipping service providing device, and executes various processes including the above-described personal authentication process.

For example, when a service user who has completed personal authentication requests browsing of article information in a certain clipping folder owned by the service user, the control unit 17 uses the service usage. , An article list page showing the title of each piece of article information contained in the clipping folder. Then, when an operation of selecting an article to be read is performed on the article list page, a Web page indicating the selected article is provided to the service user.

When various businesses start distributing new article information, they acquire the article information and store it in the article information DB 12, and store the article information newly stored in the article information DB 12. The clipping is performed in accordance with each folder definition information in the folder definition information database 13 and the result is stored in the corresponding clipping folder.

When performing such a process, the control unit 17 updates the ranking index database 15 and also updates the ranking index database which is a process of preparing source data of the clipping setting page. Execute.

The operation of the control unit 17 at the time of updating the ranking index database will be described below with reference to FIGS.

When updating the ranking index database,
The control unit 17 clears the ranking index database 15, and clears the cleared ranking index database 15.
In response to this, a keyword entry for all types of keywords stored in the folder definition information database 13 is created with the number of setters corresponding to “0”, and the number of hits for each keyword in the article information database 12 , Including that keyword, and
In the past, the number of pieces of article information that have been distributed during a predetermined period is set (step S101). In short, the control unit 17 sets the keyword column and the hit number column of the ranking index database 15 in this step S
Perform at 101. Note that the clipping service providing apparatus is configured to set (change) the “predetermined period” in step S101. Generally, the “predetermined period” of the clipping service providing apparatus is a period of about two weeks. It is operated in such a form.

Next, the control unit 17 obtains the first folder definition information in the folder definition information database as the processing target folder definition information (step S102), and processes the first keyword included in the processing target folder definition information as the processing target folder definition information. Specify as a keyword (step S1
03). Then, the control unit 17 adds “1” to the number of setters for the processing target keyword in the ranking index database 15 (step S104). Thereafter, the control unit 17 performs the related keyword information setting process (step S1).
05) is started.

As shown in FIG. 5, at the time of the related keyword information setting processing, the control unit 17 first includes, among the related keywords which are keywords other than the processing target keyword included in the processing target folder definition information, which will be described later. Step S2
It is determined whether or not the remaining processes have not been completed (step S201). In short, this step S executed at the start of the related keyword information setting process
In 201, it is determined whether the process target folder definition information includes two or more keywords or only one keyword.

When there is an unprocessed related keyword (step S201; YES), in other words, when the process target folder definition information includes two or more keywords, the control unit 17 Related keywords are identified as processing-related keywords (step S
202). Thereafter, the control unit 17 determines whether or not there is a related keyword entry relating to the processing target keyword and the processing target related keyword (in the related keywords stored in the ranking index database 15 in association with the processing target keyword, It is determined whether or not the processing target related keyword is included (step S203).
If such a related keyword entry does not exist (step S203; NO), the related index entry relating to the processing target related keyword is set to “1” for both corresponding keyword setters, and the ranking index database 15 is set. (Step S20)
4). On the other hand, when there is a related keyword entry related to the processing target keyword and the processing target related keyword (step S203; YES), the control unit 17 adds “1” to both keyword setter numbers corresponding to the relevant keyword entry. (Step S205).

After executing step S204 or S205, the control unit 17 returns to step S201 and determines whether or not unprocessed related keywords remain in the processing target folder definition information. Then, the control unit 17 determines that an unprocessed related keyword remains (step S20).
1; YES), the processes in and after step S202 are executed for the next related keyword, and the process for all the related keywords is completed (step S201; NO).
Then, the related keyword information setting process ends.

After completion of the related keyword information setting process (FIG. 4, step S105), the control unit 17 determines whether or not the process has been completed for all keywords in the process target folder definition information (step S106). If not completed (step S106; YES), the processing from step S103 is executed again. On the other hand, when the processing for all the keywords in the processing target folder definition information has been completed (step S106; NO),
The control unit 17 determines whether the processing for all the folder definition information has been completed (step S107).

If the processing for all the folder definition information has not been completed (step S107; NO), the control unit 17 executes the processing from step S102 again. Then, when the processing for all the folder definition information is completed (step S107; YE)
S), the keyword index ranking index and the related keyword ranking index are set in the ranking index database 15 (step S108). Specifically, the control unit 17 calculates the keyword-only ranking index Rs [Ki] for the keyword “Ki”, the keyword “Ki” and the related keyword “Kj” based on the following equations (1) and (2). A related keyword ranking index Rd [Ki, Kj] is calculated, and each calculation result is set in the ranking index database 15.

[0047]

(Equation 1)

In the above equations (1) and (2), N
s [Ki] is the number of setters for the keyword “Ki”, and Ns _TOTAL is the total number of setters. Nh [Ki]
Is the number of hits for the keyword “Ki”, and Nh
_TOTAL is the total number of hits. Nd [Ki, Kj]
Is the number of both keyword setters related to the related keyword “Kj” associated with the keyword “Ki”,
Nd _SUM [Ki] are all related both keyword setting The number of total related keywords associated with the keyword "Ki". Nh _SUM [Ki] is a keyword "K
This is the sum total of the number of hits related to all the related keywords associated with “i” (the number of hits associated with the same keyword as the related keyword associated with the keyword “Ki”).

That is, in step S108, the keyword-only ranking index for each keyword is
The keyword-only ranking index of keywords with the same number of hits has a larger keyword-only ranking index of keywords with more setters, and the keyword-only ranking index of keywords with the same number of setters has higher hits. This is an arithmetic expression in which the keyword-only ranking index of many keywords is larger, and the keyword-only ranking index is more affected by the number of hits than by the number of setters (1).
It is calculated based on the formula. Step S108
Then, the calculation of the related keyword ranking index is also performed based on equation (2), which is an arithmetic expression that establishes the same kind of relationship between the value of the related keyword ranking index, the number of hits, and the number of both KW setters. .

After updating the ranking index database 15 by executing steps S101 to S108, the control unit 17 performs the following processing in step S109. First, the control unit 17 extracts a predetermined number of keywords from the ranking index database 15 in descending order of the keyword-only ranking index. And the control unit 1
7 corrects the template data of the source data for the clipping setting page prepared in advance, so that a predetermined number of extracted keywords are stored in the keyword list field 121 in descending order of the corresponding keyword single ranking index. Create source data for a clipping setting page to be displayed together with a ranking according to the keyword-only ranking index (the ranking of the keyword having the largest keyword-single ranking index is first).

Then, the control unit 17 determines in step S109
Then, the ranking index database update process ends.

When receiving the related keyword display request, the control unit 17 operates as follows.

When a related keyword display request is received,
The control unit 17 extracts and extracts a predetermined number of related keywords in descending order of the keyword cooperation ranking index from the related keywords stored in the ranking index database 15 in association with the keywords included in the request. Information for displaying on a Web browser a related keyword window in which a predetermined number of related keywords are displayed together with the ranking in descending order of the keyword cooperation ranking index is created. Then, the control unit 17 returns the created information to the computer that transmitted the received related keyword display request.

When a keyword search request is received, the control unit 17 extracts (searches) a synonym for the input keyword, which is a word included in the request, from the thesaurus database 14, as shown in FIG. (Step S301). After that, the control unit 17 attempts to read the keyword alone ranking index for the input keyword and each extracted synonym from the ranking index database 15 (step S302). If no synonyms have been extracted in step S301, the control unit 17 attempts to read only the keyword-only ranking index for the input keyword in step S302.

If there is a word (input KW, synonym) from which the keyword single ranking index could be read (step S303; YES), the control unit 17 determines that one or more of the words are in descending order of the keyword single ranking index. In the survey result window indicated with the ranking,
The information to be displayed on the browser is returned to the computer that transmitted the received keyword search request (step S304), and the process for the keyword search request is completed. On the other hand, if there is no word whose keyword-only ranking index could be read (step S303; NO),
The control unit 17 returns information for displaying on the Web browser a search result window in which a message indicating that a valid search could not be performed is returned to the computer that transmitted the received keyword search request (step S30).
5) Then, the processing for the keyword search request is completed.

As described above, the clipping setting page provided by the clipping service providing apparatus according to the present embodiment includes a keyword list column 1 in which a predetermined number of keywords having a large keyword single ranking index is indicated.
21 are provided. The keyword-only ranking index is used so that the keyword-only ranking index for a keyword used by more service users takes a large value, and is used by a relatively large number of service users. The value of the keyword alone ranking index of a keyword having a low probability of hit is determined so as to be small. In addition, since the keyword-only ranking index is a parameter that is more strongly affected by the number of setters, the keyword-only ranking index for a keyword for which a large amount of information is searched uses such a keyword. (The service user who has set a keyword that causes a large amount of information to be searched changes the setting conditions, and as a result, the number of users who use such a keyword decreases.) Therefore, it is small.

Therefore, if there is a keyword that seems to be appropriate as a keyword for extracting an article desired by the user in the keyword list field 121, the setter inputs the keyword (or those keywords). By setting in the column 104, it is possible to set a search condition for clipping an article desired by the user.

The setter sets the keyword list field 11
For example, if there is no keyword that is considered appropriate as a keyword for extracting an article in a field in which the user wants to clip, for example, some kind of relation to the article in the keyword list column 111 that the user wants to clip is not included. Select a keyword and click the "Display related KW" button 12
By pressing 3, a related keyword window showing a plurality of keywords is displayed. The keywords displayed in the related keyword window are related keywords stored in the ranking index database 15 in association with the keywords selected by the service user, and are associated with certain keywords in the ranking index database. The related keyword stored in 15 is a keyword used in the same search condition formula as that keyword. Therefore, each keyword in the related keyword window is extremely likely to be a keyword related to the same field as the keyword selected by the setter from the keyword list field 121, and the setter wants to clip in the related keyword window. Often, keywords that are deemed appropriate for extracting articles are included.

Further, when the service user uses the keyword required for investigation column 124 and the investigation button 125, for example, when only the abbreviation of a certain word can be remembered, the investigation result window showing the word is displayed. You can do it.

As described above, according to the clipping service providing apparatus according to the present embodiment, by using three types of keyword presentation items, the setter can appropriately use the keyword as a keyword by another person. Many keywords that have been confirmed can be found. Therefore, according to the clipping service providing apparatus, the clipping service can be provided in a form that allows the service user to easily and accurately set the keyword.

The clipping service providing device is
The contents of the ranking index database 15 are updated daily based on the folder definition information in the folder definition information database 13, and displayed in the keyword list field 121, the related keyword window, and the evaluation result window according to the contents of the ranking index database 15. The keywords are configured to change. In other words, the clipping service providing device is also a device in which words relating to matters of interest to many people at that time are presented to the service user in a timely manner.

<Modifications> The clipping service providing apparatus according to the embodiment can perform various modifications. For example, it is not necessary to use the equations (1) and (2) for calculating the keyword single ranking index and the related keyword ranking index. For _{example, Ns [Ki] / Ns TO} TAL and Ns
[Ki] is used as a keyword-only ranking index, and Nd [Ki, Kj] / _NdSUM [Ki] or Nd [Ki, K
j] may be used as a related keyword ranking index. Also, Nh [Ki] / Nh _TOTAL or Nh [Ki] may be used as the keyword-only ranking index. However, if the keyword-only ranking index is a function of only the number of hits, a keyword for which a large number of articles will be searched will be displayed as a top keyword in a keyword list presentation item, so Nh [Ki] / Nh _{TO TAL}
It is desirable to prevent a keyword having a large Nh [Ki] from being displayed or to determine the keyword-only ranking index in consideration of the number of setters as in the embodiment.

Although the clipping service providing apparatus according to the embodiment does not calculate the number of hits related to the related keywords, the number of articles including two keywords is actually counted, and the related keyword ranking is determined from the result. An index may be calculated.

Further, the specific configuration of the clipping setting page may be different from that of the embodiment, and the present technology is applied to a clipping service of a type of providing clipped information to a service user by mail. Naturally, it may be applied.

[0065]

According to the clipping service providing apparatus of the present invention, it is possible to provide a clipping service in which search conditions can be easily set.
