本体相似度研究

不同本体之间的交互成为语义Web的首要任务,其中本体相似度计算是本体映射的关健环节。在以往的研究中,本体相似度计算通常专注于模式及其结构的匹配。目前研究朝着进一步考虑本体内部语义信息方向努力。本文描述了语义相似度栈的各个层次,依据各个层次的语义特征对目前本体相似度方法进行分类,并对每种方法进行了详细描述。最后对现有一些主要的本体间相似度计算方法进行归纳总结。这项研究工作将为人们提出新的相似度方法或者组合的计算方法作一个参考。

A Survey on Ontology Similarity

The communication between different ontologies has become the chief task for the Semantic Web. And determine similarity between ontologies is the key tache in ontology mapping. In existing application it is achieved through pattern and structure matching. So that considering more semantic information embeded in ontology is the research direction now and in the future. This paper describe every layer of similarity stack and the approaches are categorized in each layer. Meanwhile each approaches are described detailedly. At last, we apply to summarize various major approaches for similarity measure between ontologies. And it can be a reference to others to put forward a new approach or a hybria one.
