  With the use of ontologies in several domains such as semantic web,
information retrieval, artificial intelligence, the concept of similarity
measuring has become a very important domain of research. Therefore, in the
current paper, we propose our method of similarity measuring which uses the
Dijkstra algorithm to define and compute the shortest path. Then, we use this
one to compute the semantic distance between two concepts defined in the same
hierarchy of ontology. Afterward, we base on this result to compute the
semantic similarity. Finally, we present an experimental comparison between our
method and other methods of similarity measuring.
