Les mesures de similarité sémantique sont des fonctions très utilisées dans plusieurs
Semantic similarity measures are functions widely used in several informatics do- mains among which we can mention natural language processing (NLP), Bioinformatic, Infor- mation Retrievial… They allow to determinate similarity between terms or concepts which have no syntaxic similarity. The goal of this paper is to study a particular semantic similarity group: edges based semantic similarity measures. We will do a state of art of this measures. This task will come to simulations of this measures on a common knowledge base in order to compare and to evaluate their performances.
