摘要
随着语义Web的发展和Web本体语言(Web ontology language,OWL)的普及,在各个领域出现了越来越多大规模的本体,其中部分本体已历经多个版本的演变,因而需要一种简单而有效的方法,帮助人们分析和了解不同版本的本体内部的变化情况。在已有的本体指标相关工作的基础上,提出了Property层上的4个本体指标,并且选择版本更新比较完整的Open GALEN和Open Cyc本体作为数据集,基于OWL-API设计了一个实用工具,对多个版本下的本体在Ontology层、Class层和Property层的指标进行了度量。通过分析实验结果和指标所代表的意义,总结出本体指标变化所体现出的本体版本演变的规律。
With the development of semantic Web and the popularity of OWL （Web ontology language）, more and more large-scale ontologies are being developed in various fields, some of them have evolved through a number of versions. There is an increasing need for finding a simple and effective way to analyze their evolution. Inspired by some related works about analyzing and designing ontology metrics, this paper presents four ontology metrics on OWL Property-level and selects large ontologies OpenGALEN and OpenCye that have different versions as the data- sets, then designs a tool based on OWL-API to calculate ontology metrics at Ontology-level, Class-level and Property- level. In the end, this paper analyzes the experimental results and the meaning of ontology metrics, and points out some features of ontology metrics in different ontology versions.
