TREC-9 Cross-Language Information Retrieval (English-Chinese) Overview.
Fredric C. Gey, Aitao Chen · 2000
Sixteen groups participated in the TREC-9 cross-language information retrieval track which focussed on retrieving Chinese language documents in response to 25 English queries. A variety of CLIR approaches were tested and a rich set of experiments performed which measured the utility of various resources such as machine translation and parallel corpora, as well as pre- and posttranslation query expansion using pseudo-relevance feedback.
