SEARCH RESULT PROVIDING SYSTEM AND METHOD USING TAG BASED BOOLEAN QUERY MATCHING

摘要

The present invention relates to a method and a system for providing a search result using tag based Boolean query matching through which tags are extracted from a document provided by a user, a Boolean query in a possible form is created by combining the extracted tags, and a search result is provided by using tag information in determining the ranking of the search result while query groups are discriminated according to the number of tags used in the combination. The method for providing a search result using tag based Boolean query matching includes steps of (a) extracting a core tag constituting a document in a user query document; (b) constituting a complex Boolean query based on the core tag; and (c) providing a search result by repeatedly performing a process of matching a sub-query using the constituted complex Boolean query and integrating partial ranking results by the number of sub-queries.
