A review of ontology and web service composition

摘要: The term ontology is originated from Philosophy and was adopted by AI researchers to describe formal domain knowledge. Several definitions have been proposed in the last decades. most frequently cited definition that given Gruber 1993, is, defined as “an explicit specification of a conceptualization”. In other words, an model (conceptualization) which explicitly described (specified). Borst defines “formal shared conceptualization” later [Borst, 1997]. This requires, addition Gruber’s definition, conceptualization should express view between several parties, consensus rather than individual view. Also, this be expressed machine readable format. 1998, Studer et al. [Studer al., 1998] merge these two “An formal, conceptualization.”
