Abstract

Semantic Web services (SWS) and business process management (BPM) technologies are gradually applied in many domains like electronic commerce and enterprise application integration, which has unavoidably led to the requirements and concerns for effectively recovering from kinds of failures, especially in complex, untamed and dynamic Web environments. Generally, Exception handling is considered to be one of the most important mechanisms for dealing with exception conditions. However, current business process programming languages for semantic Web services provide almost no support for exception handling, and support platforms are weak in providing reliability and adaptability. In this paper, we present a novel framework for flexible exception handling and fault recovery of semantic business processes based on Semantic Programming Language (SPL). Especially, the framework provides forward recovery support with dynamically discovering and substituting failed services when an exception arises during execution by semantically equivalent or semantically similar Web services.

语义编程语言中灵活的异常处理框架

语义Web服务(SWS)和业务流程管理(BPM)技术逐渐应用于许多领域，如电子商务和企业应用程序集成，这不可避免地导致了从各种故障中有效恢复的需求和关注，特别是在复杂、不驯服和动态的Web环境中。通常，异常处理被认为是处理异常条件的最重要的机制之一。然而，目前用于语义Web服务的业务流程编程语言几乎不支持异常处理，支持平台在提供可靠性和适应性方面也很薄弱。本文提出了一种基于语义编程语言(semantic Programming Language, SPL)的语义业务流程灵活异常处理和故障恢复框架。特别是，该框架提供了前向恢复支持，当执行过程中出现异常时，可以动态地发现和替换语义等价或语义相似的Web服务。
