摘要
为了提高知识检索效率,提出了基于本体的知识建模方法.根据知识与领域本体对应关系,从领域本体构建和基于本体的知识表示两个方面研究确定基于本体的知识建模过程,形成对领域知识的有效组织与表示.讨论了基于OWL语言的领域本体构建过程和基于本体的知识表示方法.该方法保证了本体涉及领域与知识范围的一致性,考虑了本体应用过程中的效果反馈,有利于本体完善和扩展.
To improve the efficiency of knowledge retrieval,the method of ontology-based knowledge modeling is proposed.According to the corresponding relationship between knowledge and domain ontology,the knowledge modeling process has been found by considering two aspects in parallel： domain ontology construction and knowledge representation.Domain ontology construction is described by OWL,and the subject of ontology-based knowledge representation is discussed in detail.This approach ensures the consistency of the scope of ontology and knowledge.Also the feedback of ontology application is considered in modeling,which is beneficial to improvement or extension of ontology.
