A Practical and Functional Evaluation of Some Semantic Search Engines

Since the appearance of the first generations of the semantic engines, several comparative studies and categorizations were carried out for the classification of the various semantic approaches. In this paper, we would try to question and to examine some semantic search engines, among the most known and the most informed in the literature. The purpose is not to make a comparative study of these engines, but to try to show the existing possibilities in semantic search, to clarify the most used approaches and to examine some specified higher potentialities (morphological variations, synonymy, generalizations and concepts, natural languages, etc.). Our methodology is based on four search engines that we asked in a particular domain: the tourism domain. We would also try to determine some limitations bound(connected) to the lack of semantic relations between concepts.
