FIG. 1 shows the configuration of a document search system according to the present invention when the Internet is used as a communication network. The management server 1 has a close relationship with academic societies and the like, and is managed by an operator of the present system, which is a publisher that mainly handles specialized books, and is connected to the user terminal 3 via the Internet 10. I have. Also,
The management server 1 is connected to a plurality of academic societies 4, research institutes 5, and publishers 6 via the Internet 11.

The management server 1 has a database 2, and this database is published by the publisher 6, the abstract 2 of the paper published by the academic society 4, the research institution 5, or the publisher 6, and the paper data 2 a about the full text. The specialized book data 2b for the summary of the specialized book is recorded. These data are transmitted via the Internet 11 to each of the academic societies 4,
The information is periodically recorded in the database 2 from the research institution 5 or the publisher 6. In addition, the management server 1 has a search program capable of searching for the paper and the technical book by using as keywords the full text of the paper to be recorded and all the terms described in the summary of the technical book as keywords.

Next, the operation of this system and the flow of information will be described. The management server 1 searches for a relevant article by an instruction of one or more keywords from the user terminal 3,
The abstract and / or the full text of the article retrieved by the selection from the user terminal 3 is presented to the user terminal. In addition, the management server 1 searches for a corresponding specialized book according to an instruction of one or more keywords from the user terminal 3, and presents a summary of the searched specialized book to the user terminal. Hereinafter, this action,
The details of the information flow will be described with reference to FIG.

A user of the present system accesses the management server 1 from the user terminal 3 and selects a paper and / or a technical book as a search target (A). In response to this selection, the management server 1 selects a database to be searched (B), and asks the user terminal 3 whether or not items such as the title or author name of the article are known to the user. (C). When these items are known, when they are input from the user terminal 3 (C), the management server 1 immediately searches the database 2 for the corresponding paper or technical book (D), and If a paper or the like is recorded, the title or the like is presented to the user terminal 3 (G).

On the other hand, if the title of the paper is not known, one or more related keywords are input from the user terminal 3 (E). As for this keyword, a relationship such as AND and OR can be designated by using a so-called Boolean function. The management server 1 searches the database 2 for a dissertation or technical book containing the relevant keyword (F), and when finding the relevant dissertation or technical book, presents the title or the like to the user terminal 3. (G).

When the management server 1 finds the relevant paper or the like, it simultaneously presents the user terminal 3 with a selection screen of only the abstract of the paper, only the entire text, or both (H). .
