Well... what's your definition of "semantic search"? If you ask different people they would give you different definitions. Some would also claim they do "semantic search" without the need of using OWL ontologies. Wikipedia says: """ Semantic search seeks to improve search accuracy by understanding searcher intent and the contextual meaning of terms as they appear in the searchable dataspace, whether on the Web or within a closed system, to generate more relevant results. Author Seth Grimes lists "11 approaches that join semantics to search",[1] and Hildebrand et al.[2] provide an overview that lists semantic search systems and identifies other uses of semantics in the search process. Semantic Search systems consider various points including context of search, location, intent, variation of words, synonyms, generalized and specialized queries, concept matching and natural language queries to provide relevant search results.[3] """ References are interesting, worth reading. > I need to perform reasoning.
