摘要 在普适计算环境中通过语义本体来表示环境中的概念进行服务发现可以提高服务发现的鲁棒性。给出了一种基于语义的服务匹配算法,根据不同的服务请求可以通过服务类型匹配、服务输入输出参数匹配和QoS参数匹配,实现了分层次、逐步过滤不匹配的服务。同时通过服务相似度的计算为服务请求者提供最满足需求的服务。实验结果证明该算法具有较高的匹配率和较好的匹配速度,完全适用于普适计算环境。 The use of semantic descriptions of services helps automated service discovery in pervasive computing environment. A semantic-based flexible service matchmaking approach was presented. This approach matched services based on the aggregated similarities of service type, input/output parameters and QoS parameters, and used service type, input/ output parameters filtering to prune out incompatible services. At last, it may select services according to the similar function. Experimental results prove that this approach has good performance to be used in pervasive computing environment.
