Document information search apparatus and method and recording medium storing document information search program therein

Abstract

An apparatus for searching document information in response to a search request from a client is disclosed. When a document file is designated as a search condition by a search condition designating unit of the client, the unit causes contents of the designated file to be transmitted via a network. A document search unit of a search machine forms a keyword based on the file contents transmitted from the search condition designating unit, and searches similar documents from an index or selection of important words extracted from search target documents provided in a search database.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention relates to document information search apparatus and method for promptly searching necessary documents from a large amount of document data and to a recording medium in which a document information search program has been stored. More particularly, the invention relates to document information search apparatus and method for searching documents having similar contents by a simple operation such that a document file itself is designated as a search condition and to a recording medium in which a document information search program has been stored. [0003] 2. Description of the Related Arts [0004] Hitherto, in a document management system using a network environment, a document information search apparatus which can search necessary documents from a large amount of document data existing on the Internet or Ethernet and can rapidly refer to it has been provided. In a document search in such a case, the user...

AI Technical Summary

Benefits of technology

The invention provides a document information search apparatus and method that allows for quick and easy searching of similar documents. The apparatus and method allow for the transmission of a search condition as a search request to a server, which then extracts a text document from the designated file and performs a morpheme analysis to identify important words. These important words are then used to form a keyword that is used to search a database of index information. The system can also include a search machine that sends the search request to the server and performs the search based on the index information. The invention provides a computer-readable recording medium that contains the search program. The technical effects of the invention include improved efficiency and accuracy in searching for similar documents.

Problems solved by technology

When the user selects keywords which are considered to be necessary for document search from the document obtained by the Email or Internet and inputs such keywords as a search condition, if there are many keywords, it is troublesome to input them.

Unless the keywords are sufficiently designated, there is a case where a search leakage occurs and an expected search result is not obtained.

Further, there is also a case where the number of search documents which are obtained as a document list becomes extremely large.

There is a case where it is very laborious to search necessary documents by opening documents which are considered to be concerned with target documents from the document list.
