中文简介: | 本文提出了一种新的本体语义关联度量方法,特别考虑了概念之间的对象属性。我们的方法基于两个假设。首先,只使用概念层次结构和对象属性,只有少数路径可以被认为是“语义纠正”,这些路径遵循给定的规则集。其次,沿着路径中的给定边有一个代价(表示为权重),它取决于它的类型($is\mbox{-}a$, $part\mbox{-}of$,等等)、它在本体中的上下文以及它在这个路径中的位置。我们建议使用$part\mbox{-}在词法库WordNet上使用两个不同的基准来评估我们的度量。我们表明,在这种情况下,我们的度量优于经典的语义度量。 |
课程简介: | This paper presents a new semantic relatedness measure on ontologies which considers especially the object properties between the concepts. Our approach relies on two hypotheses. Firstly, using only concept hierarchy and object properties, only a few paths can be considered as “semantically corrects” and these paths obey to a given set of rules. Secondly, following a given edge in a path has a cost (represented as a weight), which depends on its type ( $is\mbox{-}a$ , $part\mbox{-}of$ , etc.), its context in the ontology and its position in this path. We propose an evaluation of our measure on the lexical base WordNet using $part\mbox{-}of$ relation with two different benchmarks. We show that, in this context, our measure outperforms the classical semantic measures. |
