This paper presents a new semantic relatedness measure on an ontology which consider especially the object properties between the concepts. Our approach relies on two hypotheses. Firstly, using only concept hierarchy and object properties, only a few numbers of paths can be considered as ``semantically correct'' 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-a, part-of, etc.), its context in the ontology and its position in the path. We propose an evaluation of our measure on the lexical base WordNet using part-of relation with two different benchmarks. We show that, in this context, our measure outperforms the classical semantic measures.
