Short Query Refinement with Query Derivation

摘要：

In this paper we present a method for short query refinement.The method includes a query retrieval model that constructs multiple derived queries for the users query,where derived queries denote a set of queries that are closely related to the query submitted by the user.Derived queries can be efficiently obtained using the indexing and retrieval of a small-unit index,which has index terms that are commonly used words and word senses.Each of the derived queries can be associated with a rank value according to its similarity to the users search query.Derived queries are useful for improving the current query refinement method and for constructing the final results.
