基于RDF的智能电网知识本体建模的关键问题研究

Key Problems in Ontology Modeling of Smart Grid Knowledge Based on RDF

智能电网的发展对电力系统领域知识的表示和应用提出了更加迫切的需求。本体技术为满足这一需求提供了一种全新途径,而且已经在相关领域取得了一些应用。对本体及RDF的基本概念进行了简要介绍,研究了基于RDF的智能电网知识本体的建模流程和基本语义关系等关键问题。在此基础上给出了一个建模实例,验证了所研究的本体建模流程的可操作性以及本体基本语义关系的实用性。

The development of smart grid constitutes more urgent demand for the representation and application of e- lectricity system domain knowledge. Ontology technology provides a new way to meet the demand, and has made ap plication in some related fields. This paper briefly introduces the basic concepts of ontology, and studies such key problem as modeling process of RDF-based smart grid knowledge ontology and basic semantic relations. Then a mod eling example is illustrated to verify the operability of the ontology modeling process, as well as the practicability of ontology basic semantic relations.
