Abstract

A document filtering apparatus includes an information input / output unit, a search word extraction unit, a first ranking search unit, a learning data unit, a classifying parameter generation unit, a second ranking search unit, and a classifying unit. The information input / output unit inputs phrasal information, and outputs search result information. The search word extraction unit extracts a search word from the phrasal information. The first ranking search unit searches a document having the search word from a database, and outputs a first ranking search result. The learning data unit prepares learning data from the first ranking search result. The classifying parameter generation unit generates a classifying parameter from the learning data. The second ranking search unit searches a document having a word corresponding to the classifying parameter from the database. The classifying unit extracts a document matching to a searcher's intention, and outputs the document as a second ranking search result.

Description

[0001] This application claims priority from Japanese Patent Application Serial No. 2003-329206 filed in the Japan Patent Office on September 19, 2003, the entire contents of which are hereby incorporated by reference. technical field [0002] The present invention relates to a method and device for document filtering, in particular to a document filtering method and device capable of effectively extracting documents matching a searcher's intention from a document database by using learning data. Background technique [0003] How to effectively retrieve documents matching the searcher's intention from the database has become a problem. In order to solve the above-mentioned problems, traditional document retrieval technology uses a combination of keywords and logical operators to perform retrieval to obtain retrieval results, and subsequent retrieval uses a new combination of keywords and logical operators to refine the retrieval results. [0004] However, a searcher needs sp...
