Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an information retrieval system and an information retrieval method, and more particularly to an information retrieval system and an information retrieval method for retrieving information stored in a storage device using retrieval conditions.

[0002]

2. Description of the Related Art Generally, when it is desired to obtain specific information from information stored in a storage device, a search process is performed by specifying a search condition. At this time, if the characteristics possessed only by the information to be acquired can be used as the search condition, the search result will include only necessary information.

[0003] However, if a search is performed under ambiguous search conditions, the search results include necessary information and information that is not necessary, and further necessary information is searched from the obtained search results. There must be. Therefore, the user repeats trial and error until necessary information is obtained, and re-creates search conditions to be appropriate.

[0004] Therefore, there are several methods for increasing the relevance rate of the search results by allowing the user to input whether or not the information included in the obtained search results matches the user's search intention. It is considered. Here, the matching rate is a ratio of the number of information items required by the user to the number of information items obtained as a search result.

Japanese Patent Laid-Open Publication No. Hei 2-245971 discloses a method of dividing a search result into conformance information and nonconformity information by using input of conformity or nonconformity with respect to each piece of information included in the retrieval result. In this method, a new search term is extracted from the frequency distribution of words appearing in each of the divided conformance information and the non-conformity information and the difference between them, added to the original search conditions, recreated the search conditions, and searched again.

According to this method, the user can obtain a search condition that derives a search result having a high relevance rate by repeatedly inputting whether the information included in the obtained search result is appropriate or not.

Japanese Patent Application Laid-Open No. 6-325101 discloses that
An electronic filing apparatus that stores search conditions used in the past in association with dates, user names, and search results is described. By using this electronic filing device, a user can create a search condition that derives a search result with a high relevance rate by referring to these data.

[0008]

However, Japanese Patent Application Laid-Open No. Hei 2-2
In the method described in Japanese Patent No. 45971, the relevance information and the non-conformity information input by the user are only used for extracting a new search word, and the relevance and non-conformity of the search result corresponding to the search formula are calculated. However, the past search formula could not be evaluated using the ratio.

In the electronic filing apparatus described in Japanese Patent Application Laid-Open No. 6-325101, even if search conditions created in the past and search results derived from the search conditions can be viewed, how much the search conditions match It was not possible to determine the rate, ie, how useful it was.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and holds created search conditions and matching information of search results derived from the search conditions. It is an object of the present invention to provide an information search system and an information search method that can be referred to when a new search condition is created by displaying the information in association with.

Here, on the search result display screen 40, the radio button 42 is checked with a pointing device or the like,
When the detail display button is pressed, “Japanese Patent Laid-Open No. 05-XXXX
After the content 47 of "X" is displayed, a state in which the check box 44 is checked assuming that the data content is suitable for the search intention is shown.

The check boxes arranged in association with the respective data displayed in the search result display column are for acquiring matching information of the search result data having the check boxes. If it is checked as shown in the check box 44, it means conformity, and if it is not checked as shown in the check box 45, it means nonconformity.

In the present embodiment, the ratio of the number of search result data matching the search intention to the total number of search result data is calculated as the matching rate. Therefore, the method described above was adopted as the method of inputting conformity information. However, a check box for conformance and a check box for nonconformity are provided, and search results that are not checked by either are omitted from the calculation of the conformance rate. It is also possible to adopt a method or a method in which a check box is not provided and only when there is an operation of displaying the contents of search result data or the like is considered to be suitable for the search intention.

When the matching information is input as described above,
The search history holding unit 32 shown in FIG. 2 holds a search history table as described below. FIG. 5 is an example of a search history table held in the search history holding unit 32 in the information search system according to the first embodiment.

The search history table 32a is designed to have session names, user names, search conditions, context information, search results, and matching information as search history items. Here, the context information is information such as a search execution date and time and a group name to which the user belongs, which is held in the search history holding unit 32 as data related to the search. In addition,
In the search history table 32a, the search conditions are the identifiers KE1 and K
It is represented by E2, KE3, and KE4. Similarly, the context information includes the identification names CO1, CO2, CO3, CO4
In the search result data, the identifiers RE1, RE2, RE3,
RE4, RE5, RE6, RE7, RE8.

Referring to the search history table 32a, in the session “SE1”, the user “U1” has the search condition “KE
1 "and" KE2 ". The search condition “KE1” has context information “CO1”, and the search condition “KE2” has context information “CO2”.
The search results obtained by searching under the search condition “KE1” are data “RE1” that matches the search intention and data “RE2” that does not match the search intention. The search results obtained by searching under the search condition “KE2” are data “RE3” that matches the search intention and data “RE4” and “RE5” that do not match the search intention.

In the session "SE2", the user "U2" has searched for the search conditions "KE3" and "KE4". The search condition “KE3” has context information “CO3”, and the search condition “KE4” has context information “CO4”. Then, the search condition “KE
The search result obtained by the search at "3" is data "RE6" [RE7] suitable for the search intention. The search result obtained by searching under the search condition “KE4” is data “RE8” that does not match the search intention.

In this example, only the matching information is stored in the search history table, and the matching rate is calculated whenever necessary. When the matching information has been input, the matching rate is calculated. It may be designed to calculate and store the matching rate in the search history table.

Next, a display screen for receiving a request for a search history while the search history is held and displaying the requested search history will be described. FIG. 6 is a diagram illustrating an example of a search history display screen in the information search system according to the first embodiment.

The session input column 51 is for the search history request unit 13 and the search history display column 53 is for the search history display. Hit part 14.

In the session input field 51, the session name "search and display" stored as the search history at this time is displayed.
"Search and History" and "Relevance" are displayed. Each session name is provided with a radio button 51a, 51b, 51c. Here, an example in which the session "search and history" is selected is shown.

When the search condition display button 52 is selected with a pointing device or the like after selecting the session name,
A search history request is issued to the search history management unit 31, and a search history display method is input to the search history display unit 14. In this example, the number of search cases and the matching rate are displayed as a display method of the search history. The search history management unit 31 searches the search history holding unit 32, searches for search history data included in the session “search and history”, and supplies the search history data to the search history display unit 14. The related information calculation unit 14a calculates the number of search results and the relevance rate for each of the search conditions included in the supplied search history data. Then, the search history display unit 14, that is, the search history display column 53 displays the search conditions, the number of search cases, and the matching rate.

According to the search history display column 53 shown in FIG.
"Approval" as a search condition for session "Search and History"
"Search""history""search * history""search * history * conformity"
It can be seen that “search * match” is included. Also, under the search condition “match”, 543 data items were searched, and it was found that 23% of the data matched the search intention. Similarly, 1132 data items were searched under the search condition “search”, and 9% of the data matched the search intention.
It turns out that it was. The search condition "History" searched 648 data, and 17% matched the search intention.
It turns out that it was. 28 for search condition "search * history"
Four data items were searched, and it was found that 21% matched the search intention. Under the search condition "search * history * conformity", 54 data items were retrieved, and it was found that 78% of the data conformed to the search intention. Under the search condition “search * conformity”, 123 data were retrieved, and it was found that 39% of the data conformed to the search intention.

As described above, the past search conditions are displayed together with their relevance rates, so that it is possible to know which search conditions were useful and to use them as references for creating more useful search conditions. be able to. In this example, the number of searches and the relevance are displayed as display methods, but a design may also be made to simultaneously display information included in the context information. Further, related information that is considered to be a reference, such as the product of the number of matching cases and the matching rate, may be calculated and displayed.

Next, a description will be given of a search history display screen in a case where the display method is provided with a condition of narrowing down the search history by the relevance ratio. FIG. 7 is a diagram illustrating another example of the search history display screen in the information search system according to the first embodiment.

Here, the session input field 71 of the search history display screen 70 shows the session input field 61 of the search history display screen 60, and the display method specification field 73 shows the same format and the same example as the display method specification field 63. . That is, an example is shown in which session names “search and display”, “search and history”, and “match rate” are displayed, each of which is provided with a radio button 71a, 71b, 71c, and the session “search and history” is selected. In the display method designation column 73, as the display method, "sort by conformance ratio", "display those above the threshold value"
There are described three items, "display items above the threshold value, sorted by date and time", each of which is accompanied by radio buttons 73a, 73b, 73c for selection. Threshold values input fields 74b and 74c for inputting a threshold value when "display those having a value equal to or larger than the threshold value" or "display items having a value equal to or larger than the threshold value sorted by date and time" are also attached. An example is shown in which "Display the above items sorted by date and time" is selected, and "20" is input as the threshold value. The display methods specified in the display method specification column 73 can be summarized as follows: "The search histories with a matching rate of 20% or more are sorted and displayed by date and time."

In the search history display section 14, a display method "sort and display search histories having a relevance ratio of 20% or more by date and time" is input from the search history request section 13. Also,
Search history data included in the session “search and history” is supplied from the history management device 30. Related information calculation unit 14
a is calculated for the supplied search history data, and the search history display unit 14 sorts search conditions having a match rate of 20% or more by date and time and displays them in the search history display column 65 in a graph.

With this display, the search condition “search * history *
It can be seen that “match” has the highest matching rate, and the search condition “search * match” has the next highest matching rate. In addition, it is found that the search condition “match” and the search condition “search * history” have a match rate slightly higher than 20%, which can be used as a reference when creating more useful search conditions.

In the present embodiment, search conditions are divided and managed in sessions, but another concept for managing a set of search conditions may be used. Further, the information search system can be designed so that a set of search conditions is not particularly created. In that case, it is not necessary to input the session name at the time of the search or to specify the session name in the search history request.

When a threshold is input from the threshold input unit 83a, the search history display unit 84 limits the display of the search history based on the threshold. Further, when the sorting using the precision or the like is designated, the control is performed. Search history request unit 8
The details of the operation of the search history display unit 84 with the search history display unit 84 will be described later in more detail.

The server 90 includes a search unit 91 and a data holding unit 92 for holding data to be searched. The search unit 91 searches the data holding unit 92 in response to an access and a search condition input from the client 80, and generates a search result. Then, the created search result is input to the search result display section 81c.

Here, the operation of the search result display section 81c will be described. First, the search result display unit 81c receiving the input of the search result from the search unit 91 performs collation on each of the search results to see if any of the search results has been a search result in the past. In this match,
Whether the search result data having the same identifier as the input search result identifier is included in the search history stored in the history management device 100, the data request to the history management device 100 based on the session name and the identifier. Is determined. If it is included, it is determined whether or not matching information has been input in the obtained search result data. If matching information has been input, it is further determined whether the input is matching. It also determines whether it is non-conforming. Then, when the collation is completed for all the search results, the search unit 91
Then, the relevance information input rate and the relevance rate at that point in time with respect to the search result input from are calculated, and the collation result and the calculation result are added to the search result and displayed.

The history management device 100 has a search history management unit 1
01 and a search history holding unit 102 that holds a search history. The search history management unit 101 responds to a data request based on the identifier from the search result display unit 81c,
The search history holding unit 102 is searched. When the search result data having the requested identifier is held as the search history, the presence / absence and content of the matching information with respect to the search result data, that is, whether or not the matching is appropriate or not, is determined by the search result display unit 81.
c. The search history management unit 101 also inputs the search history and the matching information input from the search history input unit 82 to the search history holding unit 102. Further, the search history request unit 8
3 receives a search history request, the search history holding unit 1
The search history is searched from the search history 02 and supplied to the search history display unit 84.

The search condition input means 1 shown in FIG.
Corresponds to the search condition input unit 81b. Similarly, the storage unit 2 is in the data holding unit 92, and the search unit 3 is in the search unit 9
1 and the search history input unit 82 respectively.
Further, the search history holding unit 4 stores the search history in the search history holding unit 102.
The search result display means 5 is on the search result display section 81c, the matching information input means 6 is on the matching information input section 82a, the search history requesting means 7 is on the search history requesting section 83, and the matching rate calculating means 8 is on the related information calculating section 84a. The search history display means 9 corresponds to the search history display section 84, respectively.

Here, a procedure for searching for information by the information search system of this embodiment will be described. FIG. 10 is a flowchart illustrating a procedure of information search in the information search system according to the second embodiment. Hereinafter, description will be made along the steps in the figure. [S11] The access receiving unit 81a inputs the user name, the client name, and the session name of the search condition to the search unit 91. [S12] The search condition input unit 81b inputs search conditions to the search unit 91. [S13] The search unit 91 searches the data holding unit 92 based on the search condition input in step S12, and generates a search result. [S14] The search history input unit 82 inputs search conditions, accompanying data, and search results to the search history management unit 101 as search history, and the search history management unit 101 stores the input search history in the search history storage unit 102. . [S15] The search result display unit 81c checks whether data having the same identifier is stored in the search history storage unit 102 with respect to the search result input from the search unit 91 in step S13. That is, a data request based on the same identifier is made to the search history managed by the same session name in the search history holding unit 102. [S16] When data having the same identifier is included in the search history holding unit 102, the data is acquired and it is determined whether or not the matching information is input. If the matching information has been input, the process proceeds to step S17. If the data having the same identifier is not included in the search history holding unit 102, or if the matching information has not been input even though the data is included, the search result is displayed, and the process proceeds to step 18. [S17] The search result display section 81c searches the search history holding section 1
It is determined whether the matching information of the search result data acquired from 02 is suitable or not, and the result is associated with the search result data and displayed as a search result. [S18] The search result display unit 81c determines whether or not the matching has been completed for all search results. If the search has been completed, the process proceeds to step S19, and if there is a search result that has not been collated yet, the process proceeds to step S15 again. [S19] The search result display unit 81c calculates and displays the matching information input rate and the matching rate at this point in the search result input from the search unit 91. [S20] The search result display screen of the search result display section 81c is adapted to allow input of matching information indicating whether or not matching is appropriate. The matching information input unit 82a inputs the matching information to be input to the search history management unit 101. [S21] The matching information input unit 82a determines whether to stop inputting matching information. If stopped, step S2
The process proceeds to step S2, and if not stopped, the process proceeds to step S20 again. [S22] The matching information input unit 82a performs the search history management unit 10
1 is notified that the adaptation information has been input. [S23] The search history management unit 101 receives the stoppage of the matching information input and adds the matching information input until the cancellation to the search history of the search history holding unit 102.

In the present embodiment, the determination as to whether or not the search intention performed in the past is satisfied can be associated with the search result derived from the newly created search condition via the identifier. As a result, the matching information input rate and the matching rate in the matching information input rate can be determined, and the evaluation to the search condition can be easily performed. In addition, it is possible to eliminate waste such as adding the matching information many times to the same search result.

Furthermore, in the present embodiment, since the calculation of the relevance ratio is the ratio of the number of relevance cases to the number of input cases, the relevance information need not be added to all search results. .

In the above description, an example has been described in which the matching information added in another session is not used. However, data having the same identifier added with matching information in another session is included in the search history. If it is included, it may be designed to display the matching information at the same time as the session name.

[0075]

As described above, according to the present invention, information as to whether or not a search result conforms to a search intention is stored together with a search condition and a search result, and evaluation is performed according to a request and displayed. Therefore, when a more useful search condition is to be created, the search condition created in the past can be referred to.
