For example, a database is searched from a help desk system which searches a software failure case database or the like, and is scattered on a network. WWW on the Internet (World W
There are various search systems that do not specify a database to be searched, such as an ide Web search. In these search systems, a full-text search system that inputs a keyword that a user has come up with and outputs a document that includes the keyword as a result, or keyword matching with keyword information extracted from a target document in advance Is the mainstream search system.

[0003]

However, in the above-described search system, since the target database is enormous with the development of computers and networks, the search results are obtained only by the keywords input by the user. In many cases, the search result is enormous, or there is no search result at all, and there is a problem that it takes much time by trial and error by the user to obtain a satisfactory result for the user.

[0004] In addition, an environment has become available in which a plurality of users can use the same search system over a network, and there is an increasing possibility that a plurality of users aim to obtain similar search results. Despite this, the current situation is that the past information of other users has not been successfully used.

[0005]

According to the present invention, (1) data relating to a search condition input by a user and history data relating to a search execution result are stored in a storage device, and a search condition similar to the search condition is stored. The object is solved by extracting from the history data held in the device and displaying the extracted history data when displaying a search execution result.

Further, according to the present invention, (2) when displaying the contents of data selected by the user from the search result set, the user is prompted to input data (judgment data) relating to the user's value judgment on the displayed contents. An input area for storing the determination data input by the user in a storage device, extracting the determination data for individual information constituting a search result set for the search condition input by the user, and extracting the search result. The above problem is solved by displaying the judgment data when displaying.

Further, according to the present invention, (3) data relating to a search condition input by a user and history data relating to a search execution result thereof are stored in a storage device, and from the history data, data relating to a search characteristic of each user (interest). The present invention solves the above-described problem by extracting data, storing the extracted data in a storage device, performing a search based on the interest data at every time designated in advance by a user, and notifying the user of the search result.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings.

In this embodiment, data that matches a search condition input by a user is extracted from a large amount of data stored in a database, and stored in each of the extracted data. In a system that displays the contents to the user, search results that reflect the past history up to that point are stored in the past, especially when the user performs processing in the past, and the results of the processing performed by the user in the past are stored. This is a system that displays a message and proposes the next search process.

In this embodiment, as a large amount of computerized data stored in a database to be searched, a failure case concerning the use of an existing software program, and the cause and solution of the failure are one case. The description will be made assuming a document described in text every time, but the present invention is also applicable to a search system that searches not only text but also image data, audio data, and the like.

The present invention is particularly effective when there are a plurality of users who aim to obtain similar search results. Therefore, the present invention is applicable only when a database to be searched is on a specific computer. Instead, the present invention can be applied to a search system for a plurality of different database groups existing on a network, such as a WWW search on the Internet.

FIG. 1 is a schematic image diagram of a failure case search apparatus according to an embodiment of the present invention.

In FIG. 1, a description will be given on the assumption that a user A and a user B who are having trouble printing a table created by a certain spreadsheet software use the trouble case search apparatus.

When the user A inputs a search condition that includes both the word “print” and the word “table” at a certain date and time (screen layout 301), the apparatus
Documents that match this search condition are extracted from the target database, and the number of matching documents as the search result is 4
The document ID, the document ID, and a list of document headings are displayed (screen layout 302). Further, the contents of the document (document ID 0013, document ID 0032) selected from the document list by the user A are displayed (screen layout 3
03). In order for the user A to browse the contents of each document and move to the next screen, the user selects either the “recommended button” 3033 or the “garbage button” 3034 displayed on that screen. With respect to the above-described processing of the user and a series of processing of the present apparatus, the present apparatus uses the search condition and the processing result input by the user A as a user history at any time,
Store in the table.

In the case of this example, the document ID for user A is
Since “0032” was a useful document, the “recommended button” was selected in the sense of recommending this document to another user, and the process was terminated. Similarly, the document ID 001
Since the document No. 3 was not a useful document for this purpose, this document was not recommended, so the "trash button" was selected, and the process was terminated. In this embodiment, the above 2
The user is allowed to select one of the types of buttons, but there may be a button indicating that neither of the above two types is selected (either one may be used).

Next, a user B for the purpose of obtaining a similar result inputs a search condition that includes the word "print", and the apparatus extracts documents matching the search condition from a target database. Then, the number of matching documents, the document ID, and a list of document headings are displayed as the search result (screen layout 304). However, in this case, the result was 500, and not all could be displayed as a list. Therefore, the present apparatus determines that this number is too large, and there is a user A who has input similar search conditions (search “print” and “table”) in the past. In this case, the search result is four. As a result, it is extracted from the history that the appropriate number of documents is obtained,
It is suggested to the user B that if the search condition is to search for the word “print” and the word “table”, the search result is four.

Also, in the list, for example, when a search condition that includes both “print” and “table” is input for document ID 0013, it is extracted from the history that the search is not useful for user A. And
The user B is displayed that the recommendation degree is “x”.

Further, when the user B further selects the search condition proposed by the present apparatus, documents matching the search condition are extracted from the target database, and the number of documents matching the search result, The ID and the list of document headings are displayed (screen layout 305).
With document ID 0032, the fact that it was useful for user A when the same conditions were set was extracted from the history and displayed at the top of the list display, and with document ID 0013, it was not useful for user A when the same conditions were set. Is extracted from the history and displayed below the list display.

As described above, when there are a plurality of users who aim to obtain similar search results,

In the present system, the similar search condition refers to a search condition including at least one of the keywords input in the search condition. In other words, "print"
The search conditions similar to the case where the user inputs and searches for the keyword “table” are the search conditions based on the keyword input “print” and the search conditions based on the keyword input “table”. Point. Also,
A search condition based on a keyword input of “print” and “table” and “matrix” or a search condition based on a keyword input of “print” and “matrix” is also determined as a similar search condition.

In this embodiment, since the search target is specific, the search result is extracted from the past history as it is to determine the threshold value. But W
In a search system such as a WW search in which the search target changes gradually, only the proposed search conditions are extracted from the history, and further search is performed with the search conditions, and a threshold is determined for the number of results. Perform

Next, if the display screen information is a search result list display screen and the user has entered search conditions and performed search processing, the process returns to step 6032 (step 6035).

Next, when the display screen information is the search result list display screen and the user has performed the document content display processing, the document ID and the document content are output (step 6).
036).

Next, when the display screen information is the document content display screen and the user selects the button for instructing the end of the browsing, the user inputs from the user history when outputting the document. The search condition and the result are extracted, and the process returns to step 6032 (step 603).
7).

FIG. 19 is a processing flow of the output data receiving unit 202. The operation of the output data receiving unit 202 of the present apparatus will be described with reference to FIG.

First, data is input from the proposal screen creation unit via the communication network 5 (step 2021).

Next, a screen is output to the display area 30 on the output device 3 in accordance with the format of the input data contents (step 2022).

The following describes an extended example of the present invention.
FIG. 20 is an overall configuration diagram of a failure case search device with a distribution function which is the present extended example.

In FIG. 20, every time the user history is updated, the tendency of the search condition for each user is extracted from the user history as the user interest, and the interest extraction unit 604 that stores the tendency in the user interest 703 and the target database include: Each time it is updated, user interest 703 and target database 70
The distribution unit 605 for inputting “1”, performing a search corresponding to the user's interest, and outputting the result is further stored in the CPU 6 as a program.

The user's interest 703 is stored in the external storage device 7.

The interest extraction unit 604 inputs the user history, and determines what search each user has performed in the past, and which user's search history among the search histories of other users has been referred to. Is output to the user interest 703.

Each time the target database is updated, the distribution unit 605 inputs the user's interest 703 and the target database 701, performs a search corresponding to the user's interest, and outputs the result.

FIG. 21 shows the file structure of the user interest 703.

The user interest 703 includes a plurality of records 70
Each record is a storage unit of data including four data items 7032 of “user name”, “search condition”, “same user name”, and “date and time”. For example, in the user interest 703 of FIG. 21, the “search condition” of the user whose “user name” is “A” is “print”
In addition, each time the target database is updated, "search including both" print "and" table "" is executed. It indicates that it will be performed.

Further, the “search condition” of the user whose “user name” is “B” is “search including both“ print ”and“ table ”” and the “date and time” is “DB update time”. Yes, every time the target database is updated, it indicates that "search including both" print "and" table "is performed". The “same user name” is “A”, which indicates that if user A performs another search, a similar search result is output to this user. I have. The “same user name” is another user who has referred to the search history in the past. "B"
Has performed a "search including only" print "" in the past. In this case, without displaying the document content from the search result, the search method "print and table" This search method is not extracted as the user's interest because the user selects "perform a search including both of the above."

Further, the “search condition” of the user whose “user name” is “C” is ““ screen setting ”including search”
Since “date and time” is “every morning”, it indicates that this search is performed every morning and the result is output to this user regardless of the time of updating the database.

This user interest 703 is the user history 70
2 is a file that is updated simultaneously each time it is updated, but this file can be changed, updated, or added by the user.

FIG. 22 is a processing flow of the interest extraction unit 604. The operation of the interest extraction unit 604 of the present device will be described with reference to FIG.

First, a user history is input (step 6041).

Next, the user name and its search condition are extracted from the user history, and the result is output as user interest (step 6042).

Next, if the user history has been searched by referring to another search history in the past, the user name is output as the same purpose user (step 6043).

For example, when the user history 702 in FIG. 11 is input, the “search condition” of the user whose “user” is “A” is “search including both“ print ”and“ table ””. Also, since no user name has been entered in the “reference user” of this user, there is no “same user”. Also, the timing for performing the search is “date and time”
Is “at the time of DB update”.

The "search conditions" of a user whose "user" is "B" are "search including" print "" and "search including both" print "and" table "". But,
In the case of the previous search condition, the document content is not displayed, and the search condition of another user is referred to, and the second search condition is performed. I do. Further, in this search condition, since the “reference user” is “A”, for the user B, it is assumed that the user A is a user who performs a search for the same purpose.
“Same user” is output as “A”. As for the timing for performing the search, the “date and time” is set to “when the DB is updated”.

FIG. 23 is a processing flow of the distribution unit 605. The operation of the distribution unit 605 of this device will be described with reference to FIG.

First, the user's interest 703 and the target database 701 are input (step 605).
1).

Next, for each user, the item of “date and time” is referred to, and if it is time to perform the search, the search corresponding to the item of “search condition” is performed, and the result is output (step 6052). .

In this embodiment, as a large amount of computerized data stored in the database to be searched, a failure case concerning the use of an existing software program, and the cause and solution of the failure are one case. The description will be made assuming a document described in text every time, but the present invention is also applicable to a search system that searches not only text but also image data, audio data, and the like.

The present invention is particularly effective when there are a plurality of users who aim to obtain the same search result. Therefore, the present invention is applicable only when a database to be searched is on a specific computer. Instead, the present invention can be applied to a search system for a plurality of different database groups existing on a network, such as a WWW search on the Internet.

[0131]

According to the present invention, data matching a search condition input by a user is extracted from a large amount of data stored in a database, and stored in each of the extracted data. In the case of searching for information to display the contents that have been performed to the user, in particular, the past processes performed by the user and the results thereof are stored as a history, and the next time the user performs the process, the past history up to that time is stored. Can be displayed and the next search process can be proposed.

As described above, when there are a plurality of users who aim to obtain the same search result, the search processing can be performed by the second and subsequent users with reference to the history of the previous users. Therefore, it is possible to shorten the time required to obtain the same result.
