JPS62257528A - Method for adding key word of information retrieval system - Google Patents

Abstract

PURPOSE:To sharply simplify retrieving conditions at the time of information retrieval, by adding related key words in addition to the key words of an information retrieval system and registrating the related key words in a retrieving information data base. CONSTITUTION:A related key file 4, in which key word groups related to key words which are expected to be designated at the time of retrieval are stored, is provided and, when information is registrated in an information retrieval system, words suitable for retrieval are extracted as main key words out of the information inputted from an input device 1. When the same word as one of the main key word is registrated in the index section of the related key word file 4, the related key word corresponding to the main key word is read out and stored in a retrieving information data base 6 together with the main key word through a retrieving data registrating section 5. Therefore, the retrieving conditions can sharply be simplified at the time of information retrieval, resulting in the improvement in operability at the time of inputting and retrieving information.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an information retrieval system, and particularly to a method of assigning search keywords to input information at the time of information registration.

(Prior Art) Conventionally, a method for obtaining all information from the outside as a search information database owned by an information search system is to use a keyword extraction unit to search for keywords from among the words included in friend information that are input from an input device. This is extracted and sent to the entire search data registration section, where the search data registration section uses only the keywords extracted from this input information as a search key.
It is registered in addition to the search information database.

(Problem to be Solved by the Invention) The information registration method of Tomojubei's information retrieval system described above registers only keywords included in input information as search keys in the search information database, so when searching for information,
It is necessary to accurately specify the nine search keywords included in the input information at the time of registration.

For example, in (information A) shown in Figure 3, i'j:Godai [”
, with the search keywords ``electricity'' and ``patent'', (
↑ #Information B) has the search keywords “Wa 4 Mountains”, “Chemistry”, -Patent”, and (Information C) has the search keywords “1 Kinki”,
It has the search keywords “civil engineering” and “1 patent.” In this case, even if you specify the keyword “Kinki” when searching, “Kinki” includes “Osaka” and “Wakayama”; law compliance is not mentioned. However, it is only possible to search for (beak NO), and it is not possible to search for (t'If information, information B).

In this way, if the keyword specified at the time of search does not exactly match the search keyword given to the information you want to search, but differs even slightly in form, even if the two are semantically the same or similar, However, the problem is that the above information is not searched.

It is an object of the present invention to resolve such problems and to provide i! In addition to keywords included in vc
The LIQ luck keyword is also registered as a search keyword in the search information database, and in addition to keywords that match the search keyword specified at the time of 1'# search, keywords with the same content or similar content are included. An object of the present invention is to provide a method for adding keywords to an information retrieval system that allows a wide range of searches.

(Means for solving the problem) In order to achieve the above-mentioned object, the keyword addition method of the information retrieval system of the present invention is to add a group of keywords with i;1g luck to the keywords expected to be specified at the time of search. When registering information to the information retrieval system, input! If an fC word suitable for searching is extracted as a main keyword from the information manually generated by flit (1), and the same lint as the main keyword is registered in the index section of the related keyword file (4), the main keyword is The method is to read out a group of related keywords corresponding to a keyword, pass them along with the raw keywords to a search data registration unit (5), and store them in a search information database (6).

(Embodiment) Next, an embodiment of the present invention will be explained with reference to the drawings. Fig. 1 is a block diagram of an embodiment of the present invention.

In FIG. 1, a keyboard (1) serving as an input device is used to input information including a search key and the information body to be referred to during a search.

The keyword extracting unit 2 extracts words that serve as main keywords from among the search keywords to be sent to the search information database 6 from the information input using the keyboard 1 .

The related keyword addition section 3 reads keywords related to the main keyword extracted by the keyword extraction section 2 from the related keyword file 4 and adds them to the input information and the main keyword.

The related keyword file 4 stores keywords related to search keywords (main keywords) that are expected to be specified during a search. FIG. 2 shows an example of the contents of the rJA keyword file.

The 9 keywords shown in Figure 2 are related to the keyword ``9 Osaka'' in the index section of the related keyword file.
Related keywords such as ``Kinki'', ``Kansai'', and ``Kamigata'' are stored, and related keywords such as ``Kanto'' and ``Kubbu'' that are related to the keyword ``Tokyo'' are stored.

The search data registration section uses all the main keywords extracted by the keyword extraction section 2 and the related keywords added by the related keyword addition section 3, and registers the search information in the search information database 6.

Next, (information A) in Figure 3 is j! ! The operation of the t field input to the device shown in Figure 1 will be explained in order from (43) to (d) pji.

(b) 1-#Food 7, which is the target of the search, is the input device (
(keyboard) 1. In this example, information with three keywords "Osaka", "'Electricity", and "'Patents" is input to Information@X7.

(b) Since the carefully selected information inputted from the input device 1 is a mixture of information referred to during a search and keywords, the keyword extraction section 2 extracts the search keyword from the input information.

This keyword will be your main keyword.

0 → The related keyword addition unit 3 is the keyword extraction unit 2
Keywords related to the keywords ``Osaka'', ``Electricity'', and ``Patent'' that were obtained are searched from the related keyword file 4.

Among the three keywords, the keywords ``Kinki'', ``Kansai'', and ``Kamiba'' are registered as related keywords to the keyword ``Osaka'', so these are stored in the related keyword file.Other 11 In this example, the keywords related to the key foods ``party'' and ``patent'' are not registered in the related keyword file, so nothing is read out.

2) When registering the main body of search information in the search information database 6, the inspection information registration unit 5 uses, in addition to the main keywords 1 Osaka, ``Electricity,'' and ``Patent'' obtained by the keyword extraction unit 2, "Added by related keyword addition section 3"
Search information is recorded in the search information database 6 using keywords such as ``Kinki'', ``Kansai'', and ``Kamigata''.

In this way, the n,2 information registered in the search information database 6 by the methods of (a) to (2) can be searched using the search condition, for example, "information on patents in the Kinki region." To obtain the same cumulative data from the fCia database using the keyword keyword method, the search condition is ``Kinki or Toto or Osaka, then Hyogo or Ki1, Utayama or Nara, Mayu, Mie, etc.'' The text is very long and reads, ``Information on patents in Shiga.''

(Effects of the invention) As explained above, the invention is achieved by automatically adding related keywords in addition to the keywords included in the information input of the information retrieval system and registering them in the search information database. This has the effect of greatly simplifying search conditions when information + fIL is accumulated, and improves operability when inputting information and when searching for information.

Furthermore, when searching for information, the range of information to be searched for is expanded, and it is possible to significantly reduce omissions in searches for information that is similar or has the same meaning.
