在web服务研究领域，发现满足需求的合适服务是服务重用的关键问题。一个主要的障碍是需求和服务描述之间不同的抽象层次。本文提出了一种基于本体的过程功能组织方法，并在此基础上定义推理规则。该方法通过函数描述的向量空间模型和余弦相似度判断服务是否满足流程，并利用推理规则逐字发现与流程没有关系的服务。该方法为流程的实现提供了更高效的服务发现。
In web service research field, discovering proper services to satisfy requirements is a key issue for service reuse. A main obstacle is the different levels of abstraction between requirements and service description. In this paper, we propose an ontology-based method to organize processes according to their functions, and reasoning rules are defined basing on the ontology. In this method, a service can be determined whether it can satisfy a process by the vector space model and cosine similarity of function descriptions, and reasoning rules are employed to discover services which have no relationships with the process literally. This method provides more efficient services discovery for the implementation of process.
