  The present invention relates to a search method, a search system, a search device, and a program thereof.

  In general, there is information that needs to be handled in a hierarchy, such as a folder of a file server in which data (information) is stored and an organization in a company. When such information is stored in a deep hierarchy or when the number of directory elements is not large, the target information can be reached even by displaying information through the hierarchy ( For example, Patent Document 1). However, the amount of information stored in the file server is increasing while the information explosion is screaming, and accordingly, the number of layers is increasing and the amount of information of the layer information is also increasing. As described above, when the amount of information increases, there is a problem that difficulty in searching for desired information through the hierarchy increases and search efficiency decreases.

  In order to solve the above problems, a technique described in Patent Document 2 has been proposed. In this technique, a plurality of contents classified by a plurality of hierarchized categories, a plurality of keywords expressing attributes of each content, and a content storage unit for storing a plurality of hierarchized categories are prepared. Then, from the content storage unit, the content including the input search keyword is searched, the keyword corresponding to the searched content is extracted, and based on the survey result of the category to which the extracted keyword belongs and its hierarchy From the extracted keywords, keywords belonging to a plurality of categories in the same hierarchy are extracted as common keywords, and contents are searched based on the common keywords. This increases search efficiency.

<First Embodiment>
A first embodiment for carrying out the present invention will be described in detail with reference to the drawings.

  As shown in FIG. 1, the search system according to the first embodiment of the present invention includes a search information storage device 100, an information search device 110, a hierarchical element totaling device 120, a search result display device 130, and an input device 140. The

  The search information storage device 100 has a hierarchical information database 101 and an element information database 102. As shown in FIG. 3, the element information 101 stores a document ID 301 that uniquely identifies a document that is stored in a file server (not shown), and the document is stored as directory information indicating the storage location of the document. A hierarchical path ID 302 for uniquely identifying the hierarchy being set, and a search target 303 which is a keyword indicating at least one of information indicating the content of the document and the attribute of the document. This element information can hold a plurality of elements. As shown in FIG. 3, the hierarchy information 102 holds hierarchy information to which the hierarchy described in the hierarchy path ID of the element information 101 belongs, and includes a hierarchy path ID 311 that uniquely identifies the hierarchy, and the depth of the hierarchy. A hierarchy depth 312, a hierarchy path name 313 indicating the name of the hierarchy, and a full path name 314 indicating a full path from the root to the hierarchy are configured. This hierarchical information can hold a plurality of elements.

  The information search device 110 searches for a search word from the search target 303 of the element information 101 based on the search word 111 input by the user, and the degree of whether the search word is included in each document, that is, the search word And a search score which is a degree of matching between the document and the document. Thereafter, the calculated search score is stored in the search score 321. The document ID 301 in which the search term is included in the search target 303 is stored in the document ID 322 and output as the information search result 112. As a method for calculating the search score, any generally known search scoring algorithm such as a Tf-Idf (Term frequency-Inverse document) method may be used. As shown in FIG. 3, the information search result 112 includes a search score 321 and a document ID 322. A search score document that clears a predetermined value is output as a search result.

  The hierarchical element totaling device 120 narrows down the search result based on the search condition 121 set by the user using the input device 140 and outputs the information search result 112 output from the information search device 110 as the hierarchical total result 122. As shown in FIG. 3, the hierarchical total result 122 is composed of a hierarchical depth 331, a hierarchical path name 332, a total score 333, and a document ID 334. The narrowing-down condition 121 is not necessarily specified. In the narrowing-down condition 121 set by the user, at least one of the hierarchy depth 401, the hierarchy path name 402, and the full path name 403 is designated.

  The search result display device 130 is a device that displays search results on a display screen. As shown in FIG. 2, the display screen displayed by the search result display device includes a hierarchy display selection unit 201, a search result narrowing selection display unit 202, a hierarchy name display selection unit 203, a search result display unit 204, and the same hierarchy selection unit 205. Composed.

  The input device 140 has a mechanism for selecting display contents with a keyboard / mouse, a touch screen, or the like.

  Next, the operation of the present embodiment will be described with reference to FIG. 5 which is a flowchart for explaining the operation of the present embodiment.

  When the user searches for desired information, the search term 111 is input to the information search apparatus 110 using the input device 140. The information search apparatus 110 uses the input search word 111 and the information described in the search target 303 of the element information 101 to search the user's desired search word and each document stored in the file server. The search score 321 that is the degree of matching with is calculated. Thereafter, the document ID 301 having a search score equal to or greater than a predetermined value is stored in the document ID 322 of the information search result 112, the search score is stored in the search score 321 and the information search result 112 is output (S1).

  Based on the information search result 112 and the hierarchy information 102, the hierarchy element totaling device 120 searches the hierarchy path ID 311 in the hierarchy information 102 for the hierarchy path ID of the hierarchy to which the document ID 322 of the information search result 112 belongs. The hierarchy depth 312, hierarchy path name 313, and full path name 314 associated with the hierarchy path ID 311 are read and acquired (S 2).

  Next, when the narrowing-down condition 121 is specified, the hierarchical element totaling apparatus 120 checks whether the acquired hierarchical depth 312 and the hierarchical path name 313 match the narrowing-down condition 121. When at least one of the hierarchy depth 312 and the hierarchy path name 313 is included in the narrowing condition, or when the narrowing condition 121 is included in a part of the full path name 314, it is added to the hierarchy total result 122 (S3).

  At this time, if the information is not yet included in the hierarchical total result 122, a new hierarchical total result 122 is created, and the acquired hierarchical depth 312 and hierarchical path name 313 are obtained, and the hierarchical depth 331 and hierarchical path name are obtained. 332 store in each of them. Further, the search score 321 and the document ID 322 are stored in the total score 333 and the document ID 334, respectively. On the other hand, if the hierarchical total result 122 already includes information corresponding to each of the hierarchical depth 331 and the hierarchical path name 332, the search score 321 of the information search result 112 is added to the total score 333, and the document ID 334 is obtained. To the document ID 322.

  As a result of these processes, the search results in which the hierarchy depth 331 and the hierarchy path name 332 match among the search results included in the information search result 112 are stored as a list in the document ID 334, and the total value of the search scores is The total score 333 is stored (S4).

  In the search result display device 130, information of the information search result 112 and the hierarchical count result 122 is displayed on the display screen (S5).

  Here, details of the display operation will be described with reference to the flowchart of FIG.

  In order to narrow down the information to be displayed, the search result display device 130 sorts a plurality of hierarchical aggregation results 122 from the top of the aggregation score, and ranks the elements in the order of the aggregation score (S21).

  Thereafter, an arbitrary number is extracted from the top of the elements in the order of the total score, and displayed on the search result narrowing selection display unit 202 (S22).

  When the narrowing condition 121 is specified, a plurality of elements including the hierarchical depth 312 and the hierarchical path name 313 specified by the narrowing condition 121 are extracted from the hierarchical information 102, and the full path 314 included in each hierarchical information 102 is extracted. Get a list of By displaying the acquired list of full paths 314 on the hierarchy display selection unit 201, it is possible to display and select a plurality of hierarchy lists including folder names uniquely collected (S23).

  Similarly, when the narrowing condition 121 is specified, a plurality of elements having the same hierarchical depth 312 specified by the narrowing condition 121 are extracted from the hierarchical information 102, and a list of the respective hierarchical path names 313 is acquired. By displaying the acquired list of hierarchical path names 313 on the hierarchical display selection unit 205, a plurality of hierarchical lists arranged in the same hierarchy can be displayed and selected. Also, an arbitrary number is extracted from the top of the elements in which the search score 321 of the information search result 112 is sorted from the top and arranged in the search score order, and displayed on the search result display unit 204. At that time, the document ID 322 of the information search result 112 acquires an element included in the document ID 334 in the hierarchy total result 122 and displays the hierarchy depth 331 and the hierarchy path name 332 on the hierarchy name display selection unit 203. As a result, the hierarchical position and hierarchical path name to which the search result belongs can be displayed and selected according to the search result (S24).

  When the search result narrowing selection display unit 201 is selected by the user using the input device 140, the same search word 111 is designated as the search word 111, and the selected hierarchical list is designated as the narrowing condition of the full path 314. And search again. As a result, the search is further narrowed down the designated hierarchy.

  When the search result narrowing selection display unit 202 is selected, the same search word 111 is specified as the search word 111, and the hierarchical depth 331 and the hierarchical path name 332 included in the hierarchical total result 122 are specified as the narrowing conditions. Search again. As a result, a narrowed search grouped by the specified hierarchy / specified path name is realized.

  When the hierarchy name display selection unit 203 is selected, the hierarchy display selection unit 201 and the same hierarchy selection unit 205 are designated with the hierarchy depth and the hierarchy name set in the hierarchy name display selection unit 203 as conditions, and redisplayed. To do. When a hierarchical path name in the hierarchical name display selection unit 203 is selected, the same search word 111 is designated as the search word 111, and the hierarchical depth and hierarchy described in the hierarchical name display selection unit are included in the narrow-down conditions. The path name is designated again by specifying the hierarchy depth 331 and the hierarchy path name 332. As a result, when searching for information on a document or a specified folder similar to the search result, it is possible to narrow down by the grouped hierarchical path name.

  When the search result display unit 204 is selected, a search result document or the like is displayed.

  When the same hierarchy selection unit 205 is selected, the same search word 111 is designated as the search word 111, the hierarchy depth 331 and the hierarchy path name 332 selected as the narrowing conditions are designated, and the search is performed again. Sort and rank based on search score. As a result, a narrow search is performed in the selected group in the same hierarchy.

  With the above operation, a search in which search results are grouped by folder hierarchy name and a narrow search are realized. FIG. 4 shows a display example when a search is actually performed in the file folder.

  The first effect of the present embodiment is that when a document to be searched is stored in a file server across a plurality of folders, a folder name including a lot of search information can be detected. The reason is that the search results are calculated together with the folder name and the search score is calculated.

  The second effect is that the search target documents can be narrowed down efficiently. The reason is that when the name of the folder in which the document to be searched is stored has meaning, the meaning can be recognized as a narrowing element, and information on different folders in the same hierarchy can be displayed and selected collectively.

  The third effect is that the hierarchical position where the search target document is stored is known. The reason is that the search scores are aggregated in units of hierarchy, and the stored information can be easily recognized by selecting and displaying the units of hierarchy.

<Second Embodiment>
Next, a second embodiment of the present invention will be described. In the second embodiment, the search target document is stored based on the operation management rules of the file server, and the hierarchy name is defined, but the storage hierarchy is not necessarily the same hierarchy. A search in the case of storing information having the same meaning at different hierarchical levels will be described.

  By excluding the hierarchy depth from the search conditions in the first embodiment, grouping of the same folder name is possible even when the hierarchy depth is different. The configuration of the second embodiment is the same as that shown in FIG. 1, and the display screen is the same as that shown in FIG. The following operations will be described by describing differences from the first embodiment.

  In the hierarchical element totaling device 120 according to the first embodiment, when totaling the same hierarchical name, the existing information includes the hierarchical depth 331 and the hierarchical path name 332 as the totaling condition. However, this is totaled by matching the hierarchical path name 332 without considering the hierarchical depth 331.

  In the operation of the search result display device 130, the hierarchy displayed on the hierarchy name display selection unit 203 is not necessarily a single hierarchy. Therefore, when there is a folder including a plurality of hierarchies, the folder names are arranged in units of hierarchies in the hierarchy name display selection unit 203, and coloring is performed, so that the depth of the folder hierarchy including the corresponding folder hierarchy is displayed. Can be expressed. In addition, when the display area of the folder hierarchy is small, the display area can be saved by expressing the multi-layer information with one icon.

  Referring to FIG. 7, when selecting hierarchy information represented by an icon in the hierarchy name display selection unit 203, it is possible to expand and display multi-layer information and select an arbitrary hierarchy.

  The effect of the second embodiment is that similar information that is not in the same hierarchy can be collectively displayed as a search result according to document management regulations. The reason is that information between different hierarchies can be handled in the same way because information is totaled by hierarchical path names.

  The second effect of the second embodiment is that information included between a plurality of different layers can be visualized and selected in a small display area. The reason is that the hierarchy information can be displayed as an icon and the display area can be compressed, and when selected, it can be expanded to check the existence of information for each folder hierarchy, and an arbitrary hierarchy can be selected.

  The terminal of the present invention described above can be configured by hardware as is apparent from the above description, but can also be realized by a computer program. In this case, functions and operations similar to those of the above-described embodiment are realized by a processor that operates according to a program stored in the program memory. Note that some of the functions of the above-described embodiments can be realized by a computer program.

  Although the present invention has been described with reference to the embodiments and examples, the present invention is not necessarily limited to the above-described embodiments and examples, and various modifications can be made within the scope of the technical idea. I can do it.
