APPARATUS AND METHOD FOR PROCESSING DATA STREAM USING CLUSTERED QUERY

摘要

PURPOSE: An apparatus and method for processing data stream using a clustered query are provided to perform lots of queries considering the expectation about the result of the queries. CONSTITUTION: A cluster generating unit(403) creates one or more clusters about the collected queries. The cluster generating unit extracts the representative query of the generated cluster. If a query is received from a user, a query classification unit(407) determines in which cluster the received query is belonged to. The query classification unit maps the received query as a representative query of the determined cluster.
