基于概念和语义层次的领域本体评价研究

领域本体评价是本体论和语义网研究中的重要内容.本文提出了一种基于编辑距离对领域本体中概念之间的相似度进行计算的方法.此外,通过比较给定的领域本体和"黄金标准"之间在概念的实例的安排以及概念本身的等级安排上具有的相似性,可以在语义角度对二者做出相似性判断.本文利用一个已有的军用飞机领域的本体和<中国分类主题词表>进行比较计算.实验结果表明,该方法能较为准确地计算出两个本体的概念集的相似性,也能较好地衡量本体之间的语义关系,从而实现对领域本体的有效评价.

Domain Ontology Evaluation Based on Concepts and Semantics

Domain ontology evaluation is an important research of ontology and semantic web.This paper introduces a method based on edit distance to compute the similarity between concepts of domain ontology. Besides, through comparing the similarity of concept instances and concept's hierarchies between domain ontology and "Gold Standard", we can weigh their similarity from the semantic view. This paper compares the ontology about military airplane with the concepts in "Classified Chinese Thesaurus" . The result indicates this method can compute the similarity between concept sets of two ontology,it can also weigh the semantic similarity betweens ontology. So that this method can evaluate domain ontology effectively.
