摘　　要：针对跨语言信息检索的查询翻译歧义性问题,采用交互式系统开发设计方法,对基于相关反馈的跨语言信息检索技术进行研究和分析,提出一个英汉交互式跨语言信息检索系统,实现用户辅助查询翻译、多级用户相关性判断,以及翻译优化与查询扩展等相关反馈功能,结果明显提高了检索效果。This paper introduces the interactive system development methods to resolve the ambiguity problem of query translation in Cross - Language Information Retrieval （CLIR）. After studying and analyzing on CUR techniques based on relevance feedback, an English - Chinese interactive CLIR system has been put forward. This system implements some interactive functions such as user - assisted query translation, multi - level user relevance judgment, translation enhance- ment and query expansion. Experiments show that the retrieval efficiency are obviously improved.
