摘　　要：当单个服务无法满足用户需求时,自动服务组合利用服务描述中的语义信息,自动组合多个服务,从而形成组合服务以满足用户需求。在多本体环境下,自动服务组合面临着语义异构的问题。针对此问题,提出基于本体社区的服务组合框架。该框架通过本体转换将跨本体服务组合问题转换为本体内问题,从而解决本体异构问题,并在此基础上给出一个采用传统规划技术的服务组合算法。While single service does not match the users＇ requirements, automatic service composition composes several services to accommodate the users by using the semantic description of service. In multi-ontology environment, semantic heterogeneity becomes a new challenge for automatic service composition. Aiming at this problem, this paper proposes a service composition architecture based on Ontology Community（OC）. The architecture converts service composition across ontologies into that in one OC with the help of ontology translation. Therefore, semantic heterogeneity is avoided. Based on this, it proposes a novel service composition algorithm using classic AI plan.
