As network and input technologies have improved rapidly, researches in information retrieval have become more important than ever. An user-friendly and efficient query interface will certainly facilitate utilization of an information retrieval system. In this paper, a linguistic approach to Chinese query models is proposed and investigated. It includes Chinese linguistic variables, quantifiers and combination queries. Meanwhile, an improved computation method is proposed to handle general conjunctive queries, and it is proved to be better than traditional fuzzy computation in terms of a higher level of retrieval satisfaction. Experimental results also verify that the proposed quantifiers do not only simplify a multi-criteria request, but also yield a higher level of retrieval satisfaction than do Boolean queries.

Keywords: linguistic variables, quantifier, query model, aggregation model, Chinese texts
