基于本体语言OWL的电网领域知识表示方法

摘要

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。%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 solu- tion to the problem of much data without knowledge and lays a solid foundation for the study of visualization of power ~a'id knowledge and offers supports for the safety and high efficiency of power system.
