基于本体的多源异构数据集成方法研究

Research on Heterogeneous Data with Ontology-Based Method

本体是描述概念及概念之间关系的概念模型,通过概念之间的关系来描述概念的语义。作为一种有效表现概念层次结构和语义的模型,本体在异构数据集成中得到广泛的应用。文章提出一种利用本体进行异构数据集成的方案,给出了集成系统的总体设计框架,对本体创建、本体映射等关键技术进行了研究和设计,并使用OWL描述本体及进行推理。

Ontology is defined as an explicit formal specification of a shared conceptualization. It can provide semantics through relations between concepts and can be widely used on heterogeneous data. This paper introduces a solution based on ontology to the heterogeneity of information. It puts forward the architecture of this system, and also study and design the ontology founding and mapping, then describe the ontology using OWL.
