摘要: 针对Web服务本体语言(OWL-S)过程模型存在动态交互和时序特征表达能力不足的问题,提出一种基于时序描述逻辑的过程模型形式化方法。通过对OWL-S过程模型的原子过程和组合过程语义进行形式化的描述,得到了OWL-S的过程模型的动态语义,最终实现了对OWL-S过程模型的形式化建模。实例结果验证了所提方法的可行性,为进一步的分析和验证提供了基础。

Abstract: Concerning the problem that Ontology Web Language for Services (OWL-S) process model lacks capacity for dynamic interaction and timing characteristics, a formalization method based on temporal description logic for process model was proposed. It described the atomic processes and composite processes of the OWL-S process model, and then the dynamic semantic of OWL-S process model was obtained. Finally, the formal modeling of OWL-S process model was realized. The experimental results show that the proposed method is feasible, and it provides the foundation for the analysis and validation.

Key words: Ontology Web Language for Services (OWL-S), temporal description logic, services composition, formalization, process model, modeling
