随着Web服务在Internet上的广泛应用，准确、高效地定位目标服务变得越来越困难。目前，语义Web服务被认为是最有前途的解决方案。本文提出了本体服务描述语言OSDL和查询语言OSQL，并在此基础上提出了一种基于接口语义的服务匹配算法。服务匹配问题可以归结为语义对之间的相似性，而相似性是语义对之间关系的量化，通过本体推理发现语义对之间的关系。与现有的基于语义的服务匹配算法关注本体类的后继类和祖先类之间的关系不同，本文提出的算法还关注本体类及其属性类之间的相似性。实验数据表明，为了获得更高的查全率和查准率，这一点是值得考虑的。
With the extensive applications of Web services on the Internet, to locate target services in an accurate and efficient way becomes increasingly difficult. At present, semantic Web service is regarded as the most promising approach to address the challenge. In this paper, an ontology service description language and a query language, OSDL and OSQL are proposed respectively, and then a service matchmaking algorithm based on interface semantics is proposed. The problem of service matchmaking can be attributed to the similarity between the semantic pair, and the similarity is the quantization of their relationship, which is discovered through reasoning on ontology. Unlike the existing semantics-based service matchmaking algorithms, which focus on the relationships among the successors and ancestors of ontology classes, the proposed one also pays attention to the comparability among classes and their property classes. The experiment data indicate that it is worthwhile to take the point into consideration to receive a higher recall and precision.
