摘要
OWL-S是一种面向领域本体的语义Web服务组合描述语言,也是一种可自动机器解释的语义标记语言,同时实现了Web服务功能和服务间互操作、互调用、互协作的语义化描述,是目前最重要的服务组合标准之一。提出了一种基于非马尔科夫随机PETRI网(NMSPN)的概率模型,对OWL-S描述的Web服务的控制流进行了建模和描述,并在NMSPN流程模型基础上建立了一系列的概率分析方法,实现了对语义Web服务的量化可信性的分析。
OWL-S is a semantic Web service composition-oriented ontology description and semantic markup language that can be explained by the automatic machine,while it also achieved the interoperability of Web service functions between the services,it is one of the most important service portfolio standards.This paper presented a probabilistic model based on non-Markov random PETRI NETS（NMSPN）,which can model and describe the control flow of Web services described in OWL-S.then,the paper established a series of probabilistic analysis methods to achieve a quantitative credibility to analyze the semantics of Web services-based process model based on NMSPN.
