The effects of query structure and dictionary setups in dictionary-based cross-language information retrieval 论文

摘要

this paper, the translation polysemy and the dictionary coverage problems were attacked by means of the combination of a general language MRD and a domain specific MR D i.e., a medical dictionary. The domain was restricted to medicine and health by choosing as test requests TREC's (see Harman, 1996) health related topics. The performance of translated Finnish queries against English documents was compared to the performance of original English queries against English documents. Because the domain was medicine and health, it was assumed that the medical dictionary disambiguates word senses, giving less incorrect senses than the general dictionary, and that it contains such search keys that are not found in the general dictionary
