碩士 === 國立交通大學 === 資訊科學學系 === 86 === Chinese information network has been popular in the society of allareas under the promotion of NII project. Hence, the research in the Chinese information retrieval system becomes more important thanever. In this thesis, we will investigate the design of a user-friendlylinguistic model particulary for Chinese document retrieval system.Such model is constructed based on fuzzy set theory and constructedwith linguistic variables and their syntactic structure to describlethe degree of important for each keyword. In addition, we also designaggregation operators that can reduce the ambiguity in the complexBoolean model. Finally, we propose the improved combination query method.The experimental results show that our method yield better degree ofrequest satisfaction than the method based on traditional fuzzy theory.
