DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document search apparatus for specifying a search condition and searching for a relevant document from a search target document.

[0002]

2. Description of the Related Art Generally, in a document search apparatus for searching a target document from a search target document, conditions are set by using an index (thesaurus, descriptor, etc.) or a free term (full-text search) prepared in advance, and the search is performed. Means to do this are possible. At this time, all documents that meet the search conditions are obtained as search results, and a search result set is created. Also,
When narrowing down the result sets, means such as addition of search conditions and logical operation between the result sets are taken.

At this time, there is a case where an unnecessary document which cannot be excluded by the search condition exists in the search result set. Also, even when the search is performed under the same condition, unnecessary documents exist again and need to be skipped artificially. In addition, another condition (for example, a document “how to use a personal computer in the design department” that is determined to be unnecessary when searching for “computer” & “design” is also hit ( "How to Use Personal Computers in the Design Department"))
If there is an unnecessary document from a similar viewpoint, it is necessary to skip it artificially.

As disclosed in Japanese Patent Application Laid-Open No. Hei 6-266766, a bookmark based on an arbitrary character string is added to a document searched from a search target document, and a document corresponding to the bookmark is searched. There are things, but with this technology,
A document corresponding to a bookmark is requested, and an unnecessary document cannot be excluded from a search result.

[0005]

As described above, in the conventional document search apparatus, a search result set is created using only search conditions, and even if a document is determined to be unnecessary, it is excluded if it cannot be specified in the search condition. If you ca n’t and want to eliminate any documents,
There is a problem that operability is extremely poor because it is necessary to memorize or take notes of which documents are unnecessary and to skip them artificially.

[0006] Further, once the search process is terminated, in order to view the contents of the document searched before the termination,
Again, the same search is performed by exactly the same work, and unnecessary documents must be skipped artificially. This causes a problem that the user has a large work load for the search and the document search is inefficient.

An object of the present invention has been made in view of such circumstances, and it is an object of the present invention to provide a document search apparatus capable of reducing a work load at the time of document search.

[0008]

A search device for specifying a search condition and searching for and displaying a corresponding document from a search target document, wherein a search is performed on a document searched from the search target document.
Identification information applicable document storage means for providing identification information and storing information indicating a document corresponding to each identification information, and identification information retrieval for specifying the identification information stored by the identification information applicable document storage means at the time of retrieval Time designation means.

Further, when the identification information is specified by the identification information search specification means, a means for creating a search result set by taking a logical difference between a search result set obtained from a search condition and a document corresponding to the identification information is further provided. It is characterized by having.

[0010] Further, the apparatus further comprises identification information name list display means for displaying a list of identification information stored by the identification information name storage means.

[0011] Further, it is characterized by further comprising an identification information deleting means for deleting the identification information given by the identification information giving means.

In this embodiment, it is assumed that an exclusion set list screen as shown in FIG. 5, for example, is set. On the exclusion set list screen, a "Setting" button for instructing the setting of a set to be excluded from the search result set, a "Delete" button for instructing deletion of the exclusion set by name, and registration of the exclusion set by name "Registration" button instructing addition, and "Partial registration" instructing additional registration of document IDs to be partially excluded in the excluded set list
Buttons are provided. An exclusion set list display area for displaying a list of exclusion sets and an exclusion set input area for inputting a “name” and a “memo” when registering an exclusion set are provided.

Next, the input device 2 is displayed on the exclusion set list screen shown in FIG.
Then, the corresponding exclusion set is selected (step 104), and when the "SET" button is selected and instructed by the input device 2 (step 105), the exclusion set is set and the screen transits to the initial setting screen of FIG. Here, when the input device 2 is operated and the "delete" button is selected (step 105), the exclusion set is deleted (step 106). Delete exclusion set (step 1
In step 06), when the “delete” button is instructed from the input device 2, the set is deleted in units of names of the excluded set list.

Next, on the initial setting screen shown in FIG.
When a search condition is input from a keyboard or the like (step 107), the input character string is displayed in the search condition input area. Search condition is input and "search" is performed from input device 2.
When the button is instructed to be selected, a search process is executed in the search server. A search result set is created by obtaining a logical difference between the search result set obtained by the search server (search result set for the search condition) and the exclusion set set by the exclusion function (step 108), and a search result list is displayed. (Step 109).

In this embodiment, it is assumed that a search result list screen as shown in FIG. 6, for example, is set. On the search result list screen, a "contents display" button for instructing display of contents from the search result list, a "refinement" button for instructing narrowing of search results (by adding search conditions), and a search result list An “exclusion function” button for instructing registration as an exclusion set and an “end” button for instructing termination of the search are provided.

Next, when the "contents display" button is selected by the input device 2 on the search result list screen of FIG. 6 (step 110), the contents of the corresponding document are displayed from the search result set (step 111). . Here, when the “narrow down” button is selected and instructed by the input device 2, the screen transitions to the initial screen of FIG. 4. When the “end” button is selectively instructed by the input device 2, the search is terminated and the input is terminated. When the “exclusion function” button is selected and instructed by the device 2 (step 113),
The excluded set list screen of FIG. 5 is displayed.

Step 114). In the registration of the exclusion set (step 114), when the “register” button is instructed from the input device 2, the exclusion set is registered in units of names. When the "partial registration" button is instructed from the input device 2, only the partly excluded document ID is additionally registered in the existing exclusion set.

Next, an example of function sharing in the server / client configuration in the present embodiment of FIG. 3 will be described.

First, an exclusion set setting 51, a search condition setting 52, and a search execution 5 are performed in the document search apparatus (client).
When Step 3 is executed, the search server executes search processing 54 (creation of a set of search results for search conditions). Next, a logical difference (logical operation process 55) is obtained between the search result set created by the search server and the exclusion set set in the exclusion set setting 51 in the document search device (client), and the search result list display 56 is executed. I do.

Next, an example in which a document determined to be unnecessary in FIG. 7 is set as an exclusion set will be described.

When a document relating to the design of a computer is obtained from the search target DB 161 (external storage device 6 in FIG. 1), when a search is performed using “computer” AND “design” as search conditions, a search result set 162 is created.
A document (document ID = 1, 5) different from the document that is obviously required in the search result set 162 is registered as a name and a memo as an exclusion set file 163 (the external storage device 4 in FIG. 1).
Is stored in).

Next, a description will be given of a search example using the excluded set file shown in FIG.

When a document related to computer design is obtained from the search target DB 171 (external storage device 6 in FIG. 1), search conditions of “computer” AND “design” and the exclusion set file 172 (external storage device 4 in FIG. 1) are used as search conditions. When the search is executed in the “computer design failure”, a logical difference is obtained between the search result set 173 and the set exclusion set file 174, whereby the document IDs = 1 and 5 are excluded from the search result set 173, Is created, a search result set 175 that is really needed by the user is created.

Next, a search example in which the already-created exclusion set file of FIG. 9 is used in another search will be described.

An exclusion set file 182 already created from the search target DB 181 (external storage device 6 in FIG. 1)
(Design of computer not available) in (external storage device 4 in FIG. 1)
When a document relating to the design of a personal computer is obtained by using, the search conditions "personal computer" AND "design" and the exclusion set file 182 (FIG. 1)
When a search is executed with “design of computer not allowed” in the external storage device 4), a logical difference is obtained between the search result set 183 and the set exclusion set file 184, and the document ID = 5 is obtained from the search result set 183. A rejected search result set 185 that the user really needs is created.

In the above-described embodiment, an example of the document search apparatus in the server / client configuration has been described. However, the present invention can be applied to various search apparatuses such as a commercial database search service and a homepage search on the Internet. It is possible.

[0035]

According to the present invention, a user explicitly assigns a name to a document determined to be unnecessary from a search result set obtained by a search process and saves the document as an exclusion set.
As a result, even after the search has been completed, the next time a search is performed under the same conditions and under another condition, it is determined that it is unnecessary only by selecting the name of the previously registered exclusion set from the exclusion set list. A search result set is created with documents excluded, and there is no need for the user to memorize or take notes on which documents are unnecessary, and the user can arbitrarily assign a name to be registered as an excluded set This makes it possible to register, select, and search for an exclusion set with a name that is easy for the user to use, which has the effect of improving the work efficiency of the user.
