摘要

讨论了Web服务组合中的异构性问题，将异构性问题分为语义等价Web服务之间的异构性和流程流中后续Web服务之间的异构性，将异构性问题归纳为语义冲突、数据类型冲突、结构冲突、参数数冲突、数据单元冲突和数据精度冲突六种类型。然后，设计了一种基于本体的冲突解决方案，包括定义用于业务规范的领域本体知识、定义用于描述Web服务概要信息的领域和行业术语本体知识以及定义用于转换的元本体知识。此外，还提出了实施问题

Heterogeneity resolution based on ontology in Web services composition

Heterogeneity issues in Web services composition are discussed and classified into heterogeneity between semantic equivalent Web services and heterogeneity between sequent Web services in a process flow, we induce these heterogeneity issues into six types of conflicts, namely semantic conflict, data type conflict, Structure conflict, parameter number conflict, data unit conflict and data precision conflict. Then, an ontology based conflict resolution is designed, including the definition of domain ontology knowledge for business specification, the definition of domain and industry terms ontology knowledge for describing the profile information of Web services and the definition of meta-ontology knowledge for transformation. Furthermore, the implementation issues are presented
