Abstract: The ubiquitous computing environments should provide suitable services according user' s requirement, so service matching should be made between service provider and user's requirement However, syntax-based service matcking methods and semanticbased service matching methods do not well adapt to the ubiquitous computing rectuiremenu. 13y analyzing syntax-based service matching methods and semanti}based service matching methods of ubiquitous computing,with the special requirements of efficiency, resource constraints and context awareness of the ubiquitous computing environments,we gave the corresponding solution;meanwhile we analyzed the composition service matching methods.

Key words: Ubiquitous computing, Service matching, Semantic Web service, Context-aware
