Description

  The present invention relates to an information search apparatus, an information search method, and an information search program for searching for information and displaying the search results, and more particularly to an information search apparatus and method for adjusting the display order of search results using organization information. And the program.

  In the conventional search system, when creating a list of search results, in order to display the information that the searcher wants to obtain at a higher level, the score calculated from the frequency of occurrence of keywords or the distribution rate is used, Some use information (title, creator, creation date, etc.).

  However, when searching across a company-wide crossing system, even if keywords appear frequently in the document and the score is high, we want to obtain it originally for documents created by organizations that have no contact with the searcher. In many cases, it was not a document, and there was the trouble of searching manually from the search results.

  In this regard, in Patent Document 1, the score of a document is obtained based on the appearance frequency of a search word, the obtained score is aggregated for a research target organization, the sum is calculated as an organization score, and the calculated organization score is displayed. An information retrieval device is described.

In Patent Document 2, the access frequency rate of a document is calculated for each department to which a user belongs, and the higher the access frequency rate is, the analogy that the document is more closely related to the business of the department. A document display method is described in which documents are prioritized and displayed in the order relevant to the user's department.

  With the above-described search system for searching for information in an intranet, it has become possible to search for information in a company across the company. However, in such a search system, a list of search results is created and displayed using the above-described score and the like, so even if a document intended by the searcher is hit from a large amount of information, In many cases, it was not ranked higher when displayed. For this reason, it took time and effort to search for information that he wanted to obtain from the search result list.

  On the other hand, in the information search apparatus of Patent Document 1, it is possible to easily grasp trends such as technology and knowledge possessed by each organization by using the organization score. However, this device is for summarizing the score for each organization with respect to the search word, and for examining trends such as how much information related to the search word is held for each organization by the magnitude of the score, Even if information related to the organization to which the searcher belongs is hit, if the score is small, it is not displayed at the top of the search result list, and the same problem as described above occurs.

  Further, in the document display method disclosed in Patent Document 2, it is possible to display the documents in a priority order in the order relevant to the department to which the user belongs. However, in this method, since it is necessary to obtain the document access frequency rate for each department, the accuracy of prioritization differs depending on the size of the document access frequency. For example, in the case of a document with a relatively low access frequency, the calculation accuracy of the access frequency rate for each department is also relatively low, so the prioritization accuracy is also low.

  The present invention solves the above-described problems, and provides an information search apparatus, an information search method, and an information search program that can shorten the time required for a searcher to search for information that the user wants to obtain from the search results and reduce the effort. With the goal.

  In order to achieve the above object, an information search apparatus according to the present invention searches for information, and in an information search apparatus that displays the search result, an affiliation information storage unit that stores affiliation information about the organization to which the user belongs; When displaying the search result, referring to the affiliation information in the affiliation information storage unit, the position between the affiliation between the searcher who searched for the information and the creator who created or updated the searched information or the updater Display condition control means for controlling the display condition of the search result according to the relationship.

  The information search method according to the present invention is the information search method for searching for information and displaying the search result. When storing the affiliation information about the organization to which the user belongs in the affiliation information storage unit and displaying the search result In addition, referring to the affiliation information in the affiliation information storage unit, the search is performed according to the positional relationship between the affiliations of the searcher who searched for the information and the creator or updater who created or updated the searched information. The display condition of the result is controlled.

  The information search program according to the present invention includes a process for storing information on an organization to which a user belongs in an affiliation information storage unit in a computer in the information search program for searching for information and displaying the search result, and the search When displaying the result, referring to the affiliation information in the affiliation information storage unit, the relationship between the affiliation between the searcher who searched the information and the creator or updater who created or updated the searched information In response, display condition control processing for controlling the display condition of the search result is executed.

  According to the present invention, it is possible to provide an information search apparatus, an information search method, and an information search program that can shorten the time required for a searcher to search for information that the searcher wants to obtain from the search results and reduce the time and effort.

Next, the best mode for carrying out the information search apparatus, the information search method, and the information search program according to the present invention will be described in detail with reference to the drawings.
(First embodiment)
First, a first embodiment of the present invention will be described in detail with reference to the drawings.

  Referring to FIG. 1, the information search apparatus according to the present embodiment is an application of a search system that searches for information in an intranet built in an organization such as a company. This search system includes a search index creation device 1, a search device (which constitutes the display condition control means and search result display order adjustment means of the present invention) 2, an organization information storage unit 3, an index storage unit 4, A document storage unit (storage) 5. The document storage unit 5 stores document data created or updated in advance by a user (creator or updater) belonging to an organization.

  The search index creation apparatus 1 collects search target document data from the search target document storage unit 5 in advance before executing a search by a user (searcher) belonging to an organization, and creates a search index. The organization information storage unit 3 has a hierarchical organization tree structure and information about users belonging to the organization (affiliation ID (Identification Data) of the organization (department) to which the user belongs, ID and password at the time of login, etc. Is stored in advance as organization information. The index storage unit 4 stores in advance information on documents to be searched in a form that can be easily used for searching. The search device 2 receives the search condition of the searcher as an input, searches the index storage unit 4 for the index of the document corresponding to the search condition, and outputs the search result. At this time, the search device 2 searches the affiliation ID of the creator or updater of the document retrieved from the organization information storage unit 3 and the affiliation ID of the searcher, and the affiliation of both (searcher and creator / updater) The display order of the search result of the corresponding document is rearranged and adjusted in accordance with the distance between affiliations determined by the relative positional relationship on the tree structure between (departments).

  The organization information storage unit 3 stores the user's affiliation ID in association with the user as information on the user (creator or updater, searcher). FIG. 2 shows an example of the affiliation ID stored by the organization information storage unit 3.

  FIG. 2 shows an example of an organization (department) having a tree structure in which “business headquarters”, “business departments”, “sales departments”, and “sections” are hierarchized in order from the upper hierarchy to the lower hierarchy. In the example of FIG. 2, a plurality (two) of business headquarters (first business headquarters and second business headquarters) are placed at the highest level, and a plurality of (two) business headquarters (first) Business division, second business division), multiple (two) sales departments (first sales department, second sales department) in the lower hierarchy, and multiple (three) in the lowest hierarchy This shows the case where no sections (1st section, 2nd section, 3rd section) are placed.

  In this case, an affiliation ID is assigned according to each level of the organization. That is, the affiliation ID is composed of a numeric string of predetermined digits, and indicates the organization hierarchy at each place. In the example of FIG. 2, the affiliation ID is composed of a 5-digit number string, and the first and second business headquarters located in the highest hierarchy have “1” and “2” as the first digit of the number string, respectively. Is assigned. In the first and second divisions located in the lower hierarchy, the upper second digit of the numeric string is assigned to “1” and “2”, respectively. Further, in the first and second sales departments located in the lower order, the upper third digit of the number string is assigned to “1” and “2”, respectively. In the first, second, and third sections located in the lowest hierarchy, the upper fourth digit of the numeric string is assigned to “1”, “2”, and “3”, respectively.

  The organization information storage unit 3 stores user identification information (such as a user ID) for identifying a user in addition to the user affiliation ID shown in the example of FIG. As a result, when a user is specified (authenticated), the organization ID storage unit 3 can be referenced to search for the affiliation ID of the user.

  The index storage unit 4 includes a document content storage unit 41 and a document attribute storage unit 42.

  The document content storage unit 41 stores the text information of the text part of the search target document, and the document attribute storage unit 42 stores the attribute information of the search target document as an index. Examples of attribute information include “title”, “creator”, “updater”, “creation date”, “update date”, “document type”, “affiliation information of creator / updater”, “to document” Link information ".

  The search index creation device 1 includes a collection device 11, an organization information reference device 12, and an index creation device 13.

  The collection device 11 acquires document data to be searched from the document storage unit 5 to be searched, and extracts text information and attribute information in the document.

  The organization information reference device 12 refers to the organization information storage unit 3 and acquires affiliation information including the affiliation ID of the creator / updater of the collected document.

  The index creation device 13 stores the data received from the collection device 11 and the organization information reference device 12 in the index storage unit 4 in a form that can be easily used for searching. The text information in the document is stored in the document content storage unit 41, and the attribute information is stored in the document attribute storage unit.

  The search device 2 includes an input unit 21, an affiliation search device 22, a data search device 23, a search result adjustment device (which constitutes a main part of the search result display order adjustment means of the present invention) 24, and an output unit 25. And.

  The input unit 21 receives input of login information (ID, password) from a searcher and a narrowing condition (search condition) based on a search keyword or attribute, and passes them to the belonging search device 22 and the data search device 23, respectively.

  The affiliation search device 22 receives the searcher's login information from the input unit 21, refers to the organization information storage unit 3, acquires affiliation information including the affiliation ID of the searcher, and passes it to the search result adjustment device 24.

  The data search device 23 receives a search condition from the input unit 21 and refers to the index storage unit 4 to acquire information on a document that matches the condition. At this time, a score representing the usefulness of the search target (for example, a score value normalized so as to be in the range of 0 to 1 with the highest score value being “1”) is calculated from the appearance frequency and the distribution ratio of the keywords. To the search result adjusting device 24. The present invention focuses on a method of adjusting the score value calculated as described later and adjusting the display order of search results based on the adjusted score value. Since a known method (known algorithm) can be applied to the method for calculating the score representing the usefulness of the search target from the rate or the like, details of the score calculating method are omitted.

  The search result adjustment device 24 includes an inter-affiliation distance calculation unit 241, a score adjustment unit 242, and a search result generation unit 243.

  The affiliation distance calculation unit 241 receives affiliation information including the affiliation ID of the searcher from the affiliation search device 22 and also acquires affiliation information including the affiliation ID of the creator / updater of the document that meets the search condition from the data search device. Receiving and referring to the organization information storage unit 3, based on the affiliation ID of both, the distance between affiliations is calculated from the positional relationship on the tree structure between the affiliations of both. The inter-affiliation distance may be any value (parameter) as long as it is obtained from the positional relationship between the hierarchized organizations such as the business headquarters, business departments, departments, and sections to which both belong. In this embodiment, as an example of the distance between affiliations, a weight corresponding to the distance between affiliations (a weighting factor by which the score value is multiplied) is used.

  FIG. 3 illustrates an example of setting the weight according to the distance between affiliations. In the example of FIG. 3, as the weighting condition, the department ID of the department to which the searcher belongs is compared with the department ID of the department to which the creator or updater of the search result document belongs, and the weight is determined according to the result. Set. For example, if the first four digits of both affiliation IDs are the same, they belong to the same business headquarters, the same business department, the same sales department, and the same section. Set. If the first three digits of both affiliation IDs are the same, the two sections are different, but belong to the same business headquarters, the same business department, and the same sales department. 9 ”. Also, if the first two digits of both affiliation IDs are the same, both have different sections and sales departments but belong to the same business headquarters and the same business department. To "". Also, if the first digit of the affiliation ID is the same, since both belong to the same business headquarters although the sections, sales departments, and business departments are different, the weight is further reduced and set to “0.7”. . If the first digit of the affiliation ID is different, since the sections, sales departments, business departments, and business headquarters are different, the weight is made the smallest and “0.6”. Note that the weighting conditions in FIG. 3 are merely examples, and may be appropriately changed according to circumstances such as the actual structure of the tree structure of the organization and system operation.

  For example, taking the organization shown in FIG. 2 as an example, if the affiliation ID of the searcher is “11120”, as shown in the column of Example 1 in the figure, the creator or updater of the search result document Depending on the affiliation ID, a weight is set as shown. Similarly, when the affiliation ID of the searcher is “22210”, as shown in the column of Example 2 in the figure, the weight is as shown in the figure depending on the affiliation ID of the creator or updater of the search result document. Is set.

  The score adjustment unit 242 acquires the score information of the document corresponding to the search condition from the data search device 23, acquires the affiliation distance information from the affiliation distance calculation unit 241, and the score value according to the affiliation distance Adjust. As an example of the score adjustment, in the present embodiment, the score value is adjusted by multiplying the score value by the weight set according to the weighting condition of FIG. 3 (see below for details).

  The search result generation unit 243 acquires the attribute information of the document from the data search device 23, acquires the adjusted score from the score adjustment unit 243, rearranges the search results based on the adjusted score, and performs a search. A result list is created and passed to the output unit 25.

  The output unit 25 receives a document search result list from the search result adjustment device 24 and outputs it to a display device, a printing device, or the like.

  Next, the operation of the present embodiment will be described in detail with reference to FIGS.

  Initially, with reference to FIG. 4, the operation | movement at the time of the index creation by the search index creation apparatus 1 is demonstrated.

  First, the collection device 11 accesses the search target document data stored in the document storage unit 5 and acquires data from the document storage unit 5 (step A1). The data to be acquired is created by word processing software, spreadsheet software, etc., and is binary data.

  The collection device 11 extracts a text portion and attribute information such as a title, a creator, and a creation date from this data (step A2).

  The collection device 11 passes the extracted document creator / updater information to the organization information reference device 12. The organization information reference device 12 refers to the organization information storage unit 3 based on the creator / updater information of the document, acquires affiliation information including the affiliation ID of the creator / updater, and creates the index creation device 13. (Step A3).

  The index creation device 13 converts the extracted data into a format that can be searched at high speed, and stores it in the index storage unit 4 (step A4). At this time, the index creating apparatus 13 stores the text portion of the document in the document content storage unit 41 and stores attribute information including the affiliation ID of the creator / updater of the document in the document attribute storage unit 42.

  Next, with reference to FIG. 5, the operation at the time of search by the search device 2 will be described.

  First, when starting a search, the searcher's login ID and password are input from the input unit 21 (step B1).

  The affiliation search device 22 refers to the organization information storage unit 3 and confirms whether the input ID exists and the password is correct (step B2). As a result, if the information is not stored in the organization information of the organization information storage unit 3 and is incorrect information (step B2: NO), no processing is performed and the process ends. On the other hand, if the user is correct (step B2: YES), the affiliation search device 22 refers to the organization information storage unit 3 and acquires affiliation information including the affiliation ID of the searcher corresponding to the input ID. , It passes to the affiliation distance calculation unit 241 (step B3).

  Subsequently, the search keyword or attribute narrowing condition is input by the searcher through the input unit 21 (step B4). The data search device 23 searches the index storage unit 4 based on the input information (step B5), and checks whether the corresponding document exists (step B6).

  As a result, if the corresponding document does not exist (step B6: NO), it is confirmed whether or not the re-search is executed (step B7). If not (step B7: NO), the process is ended and executed (step B7). (B7: YES) returns to step B4.

  On the other hand, when the corresponding document exists (step B6: YES), the data search device 23 passes the affiliation information including the affiliation ID of the creator / updater of the document to the inter-affiliation distance calculation unit 241, and the score adjustment unit 242. The score information of the corresponding document is passed to.

  Then, the affiliation distance calculation unit 241 refers to the organization information storage unit 3 based on the affiliation ID of the searcher received from the affiliation search device 22 and the affiliation ID of the creator / updater of the corresponding document received from the data search device 23. After that, a weight corresponding to the distance between the affiliations is calculated and passed to the score adjustment unit 242.

  Then, the score adjustment unit 242 performs weighting on the score based on the score information of the document received from the data search device 23 and the weight according to the inter-affiliation distance received from the inter-affiliation distance calculation unit 241. Is adjusted (step B7).

  The search result generation unit 243 rearranges the search result list based on the information on the corresponding document received from the data search device 23 and the score information received from the score adjustment unit 242, and passes the result to the output unit 25 (step B8). . The output unit 25 displays a list of search results after sorting.

  FIG. 6 shows an example of the search result list before the score adjustment, and FIG. 7 shows an example of the search result list after the score adjustment.

  FIG. 6 shows a search result list that is arranged in order from the title of the document with the highest score value before adjustment. In the example of FIG. 6, titles A to C having a score value of “0.90” in the first to third positions, titles D and E having a score value of “0.85” in the fourth and fifth positions, Titles F to J having a score value of “0.80” are arranged in the top six to tenth, respectively.

  In contrast to the search result list shown in FIG. 6, FIG. 7A shows the adjustment of the score value when the searcher's affiliation ID is “11120” and rearranges the search result list using the adjusted score value. Indicates the case. In this case, weights are set for the first to tenth titles A to J shown in FIG. 6 according to the affiliation IDs of the respective document creators, and the corresponding score values are multiplied by the weights. The adjusted score value is calculated, and the titles A to J are rearranged based on the adjusted score value. In the example of FIG. 7A, the titles C, G, D, J, A, E, I, B, F, and H are arranged in order from the highest adjusted score value to the first to tenth. It has been replaced.

  Similarly, in contrast to the search result list shown in FIG. 6, FIG. 7B shows a search result list using the score value adjustment and the adjusted score value when the searcher's affiliation ID is “22210”. Indicates the case of rearrangement. In the example of FIG. 7B, the titles B, F, H, A, C, D, E, G, I, and J are arranged in order from the highest adjusted score value to the first to tenth. It has been replaced.

  Therefore, according to the present embodiment, the search system for searching information in the intranet can display a document closer to the organization to which the user belongs by using the searcher's affiliation information at the top of the search results. The following effects can be achieved.

  The first effect is that the time for searching for information that the searcher wants to obtain can be shortened. The reason is that the document displayed at the top of the search result is more useful to the searcher because the searcher and the creator belong to each other.

  The second effect is that it is not necessary to input search conditions in consideration of searcher affiliation information at the time of search. The reason is that the search system side refers to the affiliation information and automatically reflects it in the search results.

  In the above embodiment, the search result display order is adjusted by rearranging the titles of the corresponding documents in the search result list so that documents closer to the organization to which the user belongs can be displayed at the top of the search results. Although described, the display condition control means for controlling the display condition of the search result of the present invention is not limited to this, and as another example, for example, the display character for displaying the title of the corresponding document in the search result list is visually displayed. To make it stand out, the size of the displayed character is made larger than the normal setting (initial setting, etc.), its display color and display font are changed to those different from the normal setting, and italic and bold fonts are used. It may be changed.

In the above embodiment, the case where the score is used when creating the search result list has been described. However, the present invention is not limited to this, and the case where a parameter value other than the score is used or Alternatively, even when parameter values such as a score are not used, it can be applied by appropriately changing the parameter values.
