基于本体的单一产品数据源组织研究

为了满足产品生命周期管理对产品信息共享和交互的需求,合理组织作为底层数据支撑核心的单一产品数据源显得尤为重要.提出了一种基于本体论的组织框架,该框架采用分层思想,将数据源分为本体层和数据层,不仅满足语义层的信息查询,还易于数据源的扩充;阐述了组织框架的具体实现方法,在分析单一产品数据源内容基础上,建立了面向产品生命周期管理的全局本体,通过数据源和本体之间的映射提取面向数据源的应用本体,并通过本体之问的映射实现本体语义一致性,从而保证了单一产品数据源的一致性、完备性和共享性.

Ontology-Based Organization for Single Source of Product Data
