Research on English-Chinese Cross-Language Information Retrieval

With the rapidly growing amount of available information, an important issue arises of matching the user queries in one language against documents in another language, i.e. cross-language information retrieval (CLIR). Based on the work in CLIR evaluation task at the 9^th Text Retrieval Conference (TREC-9), an English-Chinese CLIR system has been established. In this system, English-Chinese query translation is adopted as the dominant strategy; English queries are used as translation objects, and English-Chinese machine readable dictionary is utilized as the important knowledge source to acquire correct translations. By combining constructed Chinese monolingual IR system, the complete English-Chinese CLIR process is successfully implemented.
