面向语义网的本体整合技术的研究

On semantic Web-oriented ontology integration technology

从领域本体的结构和元素等层次,研究多粒度本体整合方法,开发出面向同一领域的本体整合工具系统.以两个电子类领域本体作为整合案例,分析OWL文件结构特征,抽取本体的主要信息以树型结构进行表示,通过元素层次和结构层次相结合的映射方法,同时采用相似度计算模型并借助本体词典Wordnet和基于统计学的方法,对领域本体进行整合操作,结果不仅实现了基于元素级层次的处理,而且实现了其语义层次上的分析.

The multi-granularity technique on ontology integration is studied from the angle of the structure and elements of domain ontology, and an ontology integration tool oriented same field is developed. Taking example for two electronic ontologies, the structural features of OWL （Web Ontology Language） files are analyzed, and the main information of the ontologies are extracted and displayedusing tree structure. The domain ontology integration is done by using mapping methods of elements and structure levels, the similarity formula, ontological dictionary Wordnet and statistical methods. The results show that the tool realizes not only integration on elements level but also analysis on semanteme level.
