Abstract

PURPOSE:To facilitate the retrieval of data by displaying the part history related to input data, detecting an exact key word by an interactive format based thereon, and executing an access to a data base. CONSTITUTION:A user checks simply a related key word for executing an access to a document data base retrieving system 7 by a thesaurus 2, and sets it as an input key word. Subsequently, the user inputs it to a retrieval history managing function 8 of a data base retrieving device 12 through a terminal equipment. In the function 8, a retrieval history data base 9 is retrieved by an input key word which is inputted, and by detecting the same key word, a name of a user who is inputted it in the past is derived from a field of a retrieval user name and presented, and all retrieval key words which this user has used in the past are presented. Based on such information, the user selects an exact key word and sends it to a document retrieving function 4, and a document data base 1 is brought to access.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a database search device for accessing desired data in a database from a terminal device.

[Prior Art] A conventional database search system will be explained by taking a literature database search system as an example. Figure 2 is a block diagram showing the configuration of a conventional literature database search system.
In the figure, (1) is the literature database to be searched,
(2) is the thesaurus of this literature database.
aurus) and is in the form of a thesaurus book.

(3) is a keyword database, and (4) is a literature search function, which has the function of searching the literature database (1) using the keyword database (3). (5) is the keyword column of the literature database, and (6) is the pointer column of the literature database, which indicates where in the literature database (1) the literature information corresponding to the keyword (5) is stored. ) is a literature database search system that includes literature database (1), keyword database (
3) Includes 1 document search function (4).

Although there are various types of databases, a literature database is used in the explanation of FIG. 2 for convenience.

Next, the operation will be explained. Conventionally, users have followed the following procedure when searching the literature database (1).

(a) The user searches the thesaurus (2) for a keyword that corresponds to the desired document, and determines this as the input keyword.

(υ) The user inputs the determined input keyword into the literature database search system (7) using a terminal device (not shown).
This is transmitted to the literature search function (4).

(c) The literature search function (4) checks whether a keyword that matches the entered keyword exists in the keyword column (5) in the keyword database (3), and if it exists, corresponds to this keyword. Based on the pointer, the literature database (1) is accessed, the literature data is read out, and it is displayed on the terminal device.

(d) On the contrary, if the keyword that matches the entered keyword does not exist in the keyword database (3), the literature search function (4) displays a message on the terminal device to the effect that the corresponding literature data does not exist. .

[Problems to be Solved by the Invention] Conventional literature database search systems use the above-mentioned search methods, so when a user wants to access desired data, a thesaurus must be investigated in detail and a keyword database must be searched. It is necessary to present a keyword that is the same as a keyword that exists in , and if the user cannot present such a keyword, there is a problem that the desired literature data cannot be obtained.

The present invention has been made to solve these problems, and aims to provide a database search device that can access data without requiring accurate keyword presentation through detailed thesaurus research.

[Means for Solving the Problems] A database search device according to the present invention has a search history management function that functions as a man-machine interface, and a search history database that has a search user name field and a search keyword field. In preparation, the user registers the history every time he or she searches for data, and when a new input keyword is input, the accumulated history related to this input keyword is displayed on the terminal device.

[Operation] In this invention, when a new input keyword is input, the accumulated J[!
Since the user does not have to input the exact keyword that exists in the keyword database, the user can simply input a keyword related to this and get the accurate keyword from the displayed history.
This keyword allows access to the data.

[Example] Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, the same reference numerals as in FIG. 2 indicate the same or corresponding parts, and (
8) is a search history management function, which is intended to implement the access method according to the present invention. A username that has been used before is registered. (11) is a search keyword column of the search history database, in which search keywords used in past searches by the users registered in the search user name column (10) are registered. (12) is a database search device in this invention.

Next, the operation of this invention will be explained.

(b) First, the user briefly searches for keywords related to the keywords used to access the literature database search system (7) (for example, keywords that correspond to superordinate concepts) in the thesaurus (2), and uses these as input keywords. .

Next, the user inputs this input keyword into the search history management function (8), which corresponds to the man-machine ° interface of the database search bag! (12), through the terminal device.

(c) The search history management function (8) searches the search history database (9) using the input keyword,
From the accumulated information, the same keyword as the input keyword is found, and the user name who has entered this keyword in the past is determined from the search user name III (10) and presented. All search keywords are presented through the terminal device.

Based on the information presented, the user selects the correct keyword through the terminal device to access the literature database search system (7), and this precise keyword is sent to the literature search function (4) and the document database ( 1)
access.

If the same keyword as the input keyword does not exist in the search history database (9), or if there is no accurate keyword corresponding to the data the user is trying to search among the presented search keywords (11), The thesaurus (2) is checked again to obtain accurate keywords, and the accurate keywords are sent to the literature search function (4) to access the literature database (1).

(d) When the data search is completed, the search history management function (
8) stores the name of the user who performed this search and the keywords used for this search in the search history and database (9).
Register in the search user name Kiri (10) and the search keyword field (lf).

Therefore, each time a literature search is performed, the number of keywords registered in the search keyword column (11) corresponding to the input keyword increases, and the user can use the By simply inputting a keyword related to the correct keyword, such as a superordinate concept, as an input keyword, the correct keyword can be easily found from the search keyword field (11).

Generally, keywords for database searches are:
In the thesaurus, descrita
ptor) and free term, the present invention can be applied to either keyword.

In addition, although the above embodiment describes a literature database, it is not limited to this, and even other databases may be used.
Needless to say, the same can be applied.

[Effects of the Invention] As explained above, the present invention provides a database search device that is disposed between the database search system and the terminal device used by the user, without modifying the already constructed database search system, and allows input The past history of the data is displayed, and based on this, the database is accessed by interactively searching for accurate keywords, eliminating the need for the user to research the thesaurus in detail to obtain the exact keywords. , which has the effect of facilitating data retrieval.
