基于本体语言OWL的电网领域知识表示方法

知识表示的方法研究是知识工程中最基本的问题,针对目前在电网领域知识表示中存在的知识表示隐晦、推理效率低、可视化水平差以及动态知识协同处理困难等弊端,提出基于网络本体语言OWL电网领域知识表示方法,给出了基于OWL的电网知识表示实例,该方法可准确直观地描述电网领域的相关知识,有利于电网领域知识提取、共享和重用,使电网运行中“数据海量,知识匮乏”的状况得到解决,为电网知识的可视化研究奠定了坚实基础,为电网安全、高效运行提供支持.

A Method of Knowledge Representation in Power Grid Domain Based on OWL

Study on the method for Knowledge representation is the most basic work in knowledge engineering.Considering the disadvantages existing in power grid domain knowledge representation-obscurity,inefficiency in reasoning,poor visualization and difficulties in collaboration of dynamic knowledge,a method based on web ontology language-OWL for power grid knowledge representation is introduced and an instance is enumerated.From the example,it’s clear that this method can accurately and visually describe the related knowledge in power grid domain and is beneficial to the extraction,sharing and reuse of knowledge.It also provides a solution to the problem of much data without knowledge and lays a solid foundation for the study of visualization of power grid knowledge and offers supports for the safety and high efficiency of power system.
