摘要
互联网的快速发展使得网络资源的表现形式日益多样化，其中信息资源的多语种问题，成为人们获取信息的主要障碍。当用户检索的信息是自己不熟悉的语言时，往往难以获得准确的检索结果。基于Lucene平台设计并实现跨语言信息检索系统，系统在提问式翻译的基础上应用查询扩展技术。实验结果表明，查询扩展技术可有效提高跨语言信息检索的查全率。
Abstract
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.
