CMU in Cross-Language Information Retrieval at NTCIR-3

We participated in the Cross-Language Information Retrieval evaluation at NTCIR-3 for the English-Chinese and English-Japanese tasks. We examined several approaches to query translation, including the use of a commercial machine translation system, a thesaurus that is automatically extracted from a parallel corpus, and a general-purpose online dictionary. The MT-based approach was most effective among these alternatives in our experiments for English-Chinese retrieval on the NTCIR-2 and 3 data. Combined use of machine translation and thesaurus extraction yielded further improvement. 1
