| Abstract: | To mismatching problem between queries and documents in current information retrieval system,a new method based on local co-occurrence analysis and concept is proposed. This method combines with concept of semantic space and local co-occurrence analysis,and the filter function of expand word is improved. The experiment results show that the information technology effect has been improved greatly and has better retrieval performance compare with traditional query expansion methods. |
| Keywords: | semantic query expansion concept local co-occurrence analysis information retrieval |
