Experiments on Cross-language and Patent Retrieval at NTCIR-3 Workshop
Aitao Chen, Fredric C. Gey · 2002
The Berkeley group participated in the cross-language retrieval task and the patent retrieval task at the third NTCIR workshop. This paper describes our experiments on cross-language and patent retrieval. We present an automatic relevance feedback proce-dure for document ranking formula based on logistic regression, and a procedure for automatically extract-ing Chinese/Japanese translations of English words from search results returned from Internet search en-gines using English words as queries.
