主　　题：Chinese query case-based reasoning(CBR) Case- Base case retrieval comparability 

摘      要：In this paper, the method of tmderstanding GIS Chinese query based on CBR （case-based reasoning） is proposed. The CaseBase is designed on the grammar rule of Chinese query sentences, the cases that pick up the character of standard query language （SQL） and are expressed in form semantics. In retrieval, the concepts of target comparability, structure comparability and individual comparability are given. The algorithm of case retrieval searches first the case of structure comparability and then individual comparability. The SQL reasoning algorithm that first parses form semantics, then reasons on structure comparability, and finally reasons on individual comparability is realized. In the actual GIS, the structure comparability and individual comparability are tested respectively. The experiment results show that the strategy of CBR is correct and feasible. With the size of CaseBase increasing through studies, the CaseBase will eventually be perfected. The effect of retrieval and reasoning will become better and better.
