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 5 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 thesis of this literature database.
saurus) 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. (7) ) is a literature database search system that includes a literature database (1) and a keyword database (3>9 literature search functions (4)).

(8a) is a terminal device for using the literature database search system (7).

Although there are various types of databases, a literature database is used in FIG. 5 for convenience of explanation.

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 the terminal device (8a), and this is transmitted to the literature search function (4).

(c) In the literature search function (4), it is checked whether a keyword matching the input keyword exists in the keyword column (5) in the keyword database (3), and if it exists, it is matched with 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 (8a).

(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) sends a message to the terminal device (8a) to the effect that the corresponding literature data does not exist. Display to.

[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 literature data, a thesaurus is searched to find out the keywords that exist in the database. However, if the user is unable to present the correct keyword to the literature search function, there is a problem in that the user cannot obtain the desired literature data.

This invention was made in order to solve such problems, and a database search allows users to access desired literature data in an interactive manner via a terminal device by simply inputting a concept related to the desired literature data. The purpose is to obtain equipment.

[Means for Solving the Problems] A database search device according to the present invention includes a concept extraction database and an intelligent document search function, and allows a user to input a superordinate concept related to a document desired to search from a terminal device. This allows the system to step-by-step present multiple lower-level concepts and keywords related to the input higher-level concept, allowing the user to repeatedly select and extract the correct keyword.

[Operations] In this invention, the correct keywords are obtained interactively by the user inputting a concept related to the desired literature data, without consulting a thesaurus and presenting the exact keywords existing in the keyword database.

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

(c) The user inputs the correct keyword (5) in the keyword database (3) according to the contents of the guide displayed on the terminal device (8).
and access the desired document in the same way as before.

Next, the process of searching for the correct keyword (5) in the concept extraction database (10) will be explained with reference to the flowchart of FIG.

When the concept extraction database (10) has the contents shown in FIG.
(artificial intelligence)
If you enter the concept J, the intelligent literature search function (9
) searches for a schema called rAIJ. If a corresponding schema is found, the slot "level" of that schema
(13), and if the content is "concept", the slot "lower-" is checked, and the content is displayed on the terminal device (8) to prompt the user to make a selection. As shown in Figure 3, FAI
, when the concept of ``lower'' slot is H/W, S/I4, and the terminal device (8) displays ``Is it rH/%ll or S/Ill?j'' (Here, H/W means hardware, and S/% II means software.) The user selects the one that is related to his or her search target data. For example, r H/vJ or S/% r S/W in response to the question “Is it ll?”
If the answer is J, the schema is further searched, and this time the content of the "lower" slot is Basic S/W, Application S/%ll, and the terminal device (8) is "Basic S/%II? , Application S/%'
"Is it l?" is displayed. Here, if the user answers "Basic S/%ll", the contents of the slot "lower" will become "Programming language, tools...", and if the user answers "Programming language", the content of the slot "Level" will become "Programming language, tool...". The keyword is displayed for the first time. In other words, the user can extract the correct keywords by inputting a superordinate concept and selecting its subordinate concepts, making it easy to find keywords (5) that can access the actual literature database (1) from conceptual words. can be found.

Note that the slot "Use J (15)" is for checking whether the keyword matches what the user desires. For example, the slot "Lower" of the frame "Programming language" contains PROLOG, PROLOG, It's not all about LISP (although there are also FORTRAN, COBOL, etc.)
Since the first concept input by the user is rAIJ, it is used to select only the applicable concept while confirming the usage by "calculator, . . .".

Input the correct keywords obtained in the concept extraction database (10) into the literature search function (4),
Access the literature database (1), receive the obtained literature data from the literature search function (4), and send it to the terminal device (8).

They can be read as database, search function, and intelligent search function, respectively.

Further, in the above embodiment, a frame is used as the structure of the concept extraction database (10), but the same implementation as described above can be performed using a general relational database.

[Effects of the Invention] As explained above, the present invention enables the user to interactively obtain the correct keywords and retrieve the data by simply inputting a concept related to the desired data without modifying the already constructed database search system. This has the effect of allowing access.
