基于Ontology的工作流知识管理系统的应用研究

Research and Application of Workflow Knowledge Management System Based on Ontology

知识管理已成为企业在信息化条件下提高竞争力的必要手段,工作流系统是支持工作流定义、执行和监控的计算机软件系统。针对工作流系统应用在企业知识管理时面临的流程数据整合不易、文件内容词汇关系的不明确与存取控制不便等问题,提出了一种基于本体的工作流知识管理系统架构,并介绍了其设计及实现机制。该系统以XML作为流程文件交换与存储格式,流程中的知识可以结构化地保存下来,便于在各部门的异质系统间传递;并利用了本体论的方法将企业内的组织、计划、人员等不同知识领域所包含的概念及关联特性整合进工作流程中,改善了部门间的语意差异,更好地实现了工作流中知识的应用效率与一致性。

Knowledge management is necessary for enterprise＇ s competition. Workflow system is computer software, which supports workflow definition, performance and surveillance. When workflow system is applying in knowledge management, it faces the drawbacks including uneasy data integration, implicit definition of vocabulary, and inflexible control of authentication access. Puts forward a workflow knowledge management system architecture based on ontology, and introduces the designs and implementations. The system uses XML as the format of file exchange and storage, so it can store knowledge structurally and transfers it in heterogeneous system. The system also integrates different domain knowledge＇s concept and relation into the workflow with the help of ontology. It enhances the semantics and realizes the knowledge applying efficiency and consistency.
