چکیده
Users might use general terms to query the information in need, when the exact keyword is unknown. We treat these inexact query terms as general queries. In this paper, we consturct a test data set to evaluate the performance of online search engine on searching Wikipedia with general queries and exact queries. We also proposed a new query expansion method that performs better on general queries. The Wikipedia query expansion method is regarding the Wikipedia as a thesaurus to find candidates of query expansion. The expanded queries are then combined with the pseudo relevance feedback. The performance of this method is better than online search engine on the general queries.
