基于构件的本体扩展工作流的构架研究与应用

Study and Application of Component-based Ontology Extended Workflow Architecture

几乎所有的行业都涉及工作流,用以协调任务之间的执行。由构件组成的工作流,可以提高系统的复用性,加快系统的开发和配置速度。但是构件之间句法语义的不同,决定了它们是不能直接组装的。论文提出基于本体扩展的工作流构件,使用本体来解决不同构件之间的元数据映射,并实现了基于构件的本体扩展工作流的框架,做出了具体实施。

Workflow coordinates execution of multiple tasks.Encapsulation of such activities in the form of reusable modules or workflow components,which can be assembled to create complex workfiows.In order to assembly of complex workflows from semantically heterogeneous components,we need develop workflows from independently developed, semantically heterogeneous information sources and software components.Great progress has been made in ontology- driven information integration and component-based workflows.In this paper,framework of ontology-extended component- based workflows is presented to address the need for a theoretically sound basis for composition of semantically heterogeneous workflow components into semantically consistent workflows,and implementation of the framework is accordingly presented.
