1. An information retrieving system comprising:
- a data registration section in which a keyword and an attribute of the keyword are extracted from a source document;
a database where a keyword and an attribute of the keyword are stored together with a document ID for discriminating the source document;
a retrieval key input section which captures at least one keyword;
an attribute rule registration section where a pair of an attribute keyword and the attribute of the attribute keyword is registered, the attribute keyword being defined as a keyword whose attribute is used for retrieval;
a keyword conversion section which converts a keyword captured from said retrieval key input section into an attribute corresponding to the attribute keyword if the keyword is an attribute keyword registered in said attribute rule registration section;
a retrieval section which retrieves information from the database on the basis of captured keywords and attributes converted from keywords by said keyword conversion section;
an output section which outputs a retrieval result obtained by the retrieval section; and
a computer for processing information in the above-mentioned sections wherein the data registration section comprises;
a document input section which captures an electronic document serving as a source of data to be registered in the database;
a keyword extraction section which extracts a keyword from the electronic document captured by the document input section;
an attribute giving section which gives an attribute to the keyword extracted by the keyword extraction section; and
a registration section which registers a correspondence of the keyword extracted by the keyword extraction section to the attribute given by the attribute giving section in the database together with a document ID unique to the electronic document.

Abstract
In this invention, a database in which a keyword and an attribute of the keyword are stored together with a document ID for discriminating a source document is arranged, at least one keyword and/or retrieval key constituted by attribute information which is not specified as a keyword is input, and the database is retrieved on the basis of the keyword and/or the attribute of the attribute information. As a result, the source document can be specified by the keyword input as the retrieval key, and retrieval intention is reflected by the attribute information input as the retrieval key.
