Applications of Query Expansion in Cross-Language Information Retrieval
With the rapid development of the Internet, the network resources have too many forms. Meanwhile, most of them are described in differ-ent languages, which has become a mainly obstacle when people get information. People can't get precise results if the information re-source uses a language that is unfamiliar to them. Designs and implements a cross-language information retrieval system which uses query translation approach and query expansion technology based on Lucene. The experimental results show that the recall of cross-language information retrieval is improved when query expansion is applied.
