Abstract

This article proposes a formal specification method for Web services composition based on context-aware semantic planning graph technique. The authors first use a graph planning technique to conceive an adaptable semantic Web services composition. They use an ontology based context model for extending Web services descriptions with information about the most suitable context for its use. Then, the composition problem is transformed into a semantic context aware graph planning problem to build a set of best-composed Web services based on the user's context. Because of the error-prone nature of the Web services composition process, and with the integration of context information in this process, the complexity of Web services-based systems is increasing, hence the need for formal specification and verification approaches of such systems. The authors seek to use CCA calculus, to formalize Web services composition expressed in terms of adaptable OWL-S, and transform the description of workflow patterns into the description patterns in terms of CCA, a calculus for context-aware ambients.

自适应语义Web服务组合的正式规范

本文提出了一种基于上下文感知语义规划图技术的Web服务组合形式化规范方法。作者首先使用图规划技术来构思一个可适应的语义Web服务组合。它们使用基于本体的上下文模型来扩展带有最适合其使用的上下文信息的Web服务描述。然后，将组合问题转化为语义上下文感知的图规划问题，根据用户的上下文构建一组最佳组合的Web服务。由于Web服务组合过程容易出错的特性，以及该过程中上下文信息的集成，基于Web服务的系统的复杂性正在增加，因此需要对此类系统进行正式的规范和验证方法。作者试图使用CCA演算来形式化用可适应的OWL-S表示的Web服务组合，并将工作流模式的描述转换为CCA(上下文感知环境的演算)的描述模式。
