2000 Proceedings of the 2000 Joint SIGDAT conference on Empirical methods in natural language processing and very large corpora held in conjunction with the 38th Annual Meeting of the Association for Computational Linguistics -  
This paper proposed a new query translation method based on the mutual information matrices of terms in the Chinese and English corpora. Instead of looking up a • bilingual phrase dictionary, the compositional phrase (the translation of phrase can be derived from the translation of its components) in the query can be indirectly translated via a general-purpose Chinese-English dictionary look-up procedure. A novel selection method for translations of query terms is also presented in detail. Our

The evaluation results show that the retrieval performance achieved by our query translation method is about 73% of monolingual information retrieval and is about 28% higher than that of simple wordby-word translation way.
