中文简介:
由于本体的高度异质性,需要多种方法的组合才能正确发现其元素之间的语义对应关系。本体匹配工具可以看作是几个匹配组件的集合,每个组件实现处理特定异构性类型(术语,结构或语义)的特定方法。此外,引入映射选择模块以滤除最可能的映射候选。本文提出了在本体匹配系统内协同工作的这些组件之间相互作用的实证研究。借助Ontology Alignment Evaluation Initiative的数据集,我们进行了几项实验研究。首先,我们对映射选择模块对术语结构匹配器性能的影响感兴趣,揭示了使用全局方法与本地方法相比的优势。此外,我们对存在来自术语方法的噪声输入存在的结构匹配器的性能缺陷进行了广泛的研究。最后,我们分析了结构和语义成分相对于来自不同术语匹配器的输入的行为。
课程简介: Due to the high heterogeneity of ontologies, a combination of many methods is necessary in order to discover correctly the semantic correspondences between their elements. An ontology matching tool can be seen as a collection of several matching components, each implementing a specific method dealing with a specific heterogeneity type (terminological, structural or semantic). In addition, a mapping selection module is introduced to filter out the most likely mapping candidates. This paper proposes an empirical study of the interaction between these components working together inside an ontology matching system. By the help of datasets from the Ontology Alignment Evaluation Initiative, we have carried out several experimental studies. In the first place, we have been interested in the impact of the mapping selection module on the performance of terminological and structural matchers revealing the advantage of using global methods vs. local ones. Further, we have carried an extensive study on the flaw of the performance of a structural matcher in the presence of noisy input coming from a terminological method. Finally, we have analyzed the behavior of a structural and a semantic component with respect to inputs taken from different terminological matchers.
