普适计算服务匹配技术研究

在普适计算环境下需要根据用户的需求提供合适的服务,这需要对用户请求的服务和环境提供的服务进行服务的匹配.而目前使用的基于语法的服务匹配和基于语义的服务匹配都不能很好地适应普适计算环境的高效、资源约束和上下文感知的要求.通过分析普适计算环境下主要的基于语法的和基于语义的服务匹配技术,给出普适计算环境下在高效、资源约束和上下文感知的特殊要求下服务匹配的解决方案,并就面向服务组合的服务匹配进行了分析.

Researches on Ubiquitous Computing Service Matching

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.
