Abstract

Although query expansion (QE) has been extensively studied to provide more specific and accurate information for user query, little has been explored to study the importance of combined solution which includes extract terms, select terms correlation, and weight terms correl- ation for QE. The experimental results, based on two real Chinese query logs with 8-14 millions queries, show that the precision varies from 10% to 90% of the top 5 expansion terms.
