基于词典的英汉双向跨语言信息检索方法

Dictionary-based Method for English-Chinese Bidirectional Cross-Language Information Retrieval

基于文本检索会议关于英汉跨语言信息检索的任务评价,分别以英汉双向查询翻译和英汉查询为主导策略与翻译对象,采用英汉电子词典作为获取翻译知识的知识源,结合构建的英汉单语信息检索系统,实现完整的英汉双向跨语言信息检索过程。实验结果验证了该系统的有效性。

Based on the task evaluation of English-Chinese Cross-Language Information Retrieval（CLIR） in Text Retrieval Conference（TREC）, this paper adopts English-Chinese bidirectional query translation as tile dominant strategy and uses English-Chinese queries as the translation object. English and Chinese electronic dictionaries are utilized as the knowledge source to acquire the translation knowledge and combined with the established English-Chinese monolingual Information Retrieval（IR） systems. The whole bidirectional CLIR process can be implemented. Experimental results show that this system is effective.
