基于Web的跨语言信息检索研究综述

Web-based Cross Language Information Retrieval Technique

回顾了近年来基于Web的跨语言信息检索技术的理论研究和发展现状,针对跨语言信息检索中基于语料库的方法,就其中语料库的构建和使用问题进行了阐述。比较分析和总结了两方面的技术:一是利用互联网上丰富的双语资源来建立大规模双语语料库的技术,二是目前运用较多的几种查询翻译模型构建技术。最后,展望了该领域的研究前景和发展方向。

The theoretical research and development status of the Web-based cross-language information retrieval technique in recent years is reviewed. For the technique based on corpus, the approaches of how to construct the parallel corpus from the Web pages and how to use it to realize the modeling of the query translation are summarized. Finally, the study prospect is discussed.
