Desambiguação de relações em tesauros e o seu reúso em ontologias

Abstract

A thesaurus is composed of concepts organized by a paradigm network (essential and stable relations between terms and concepts), and a syntagmatic network (specific relations in a context of use). Thesauri and ontologies are knowledge organization systems (SOCs) that are capable of representing the knowledge base of a domain, based on rules and structuring criteria. The terminological basis of thesauri can be used in the construction of ontologies. However, not always the relations established in the structure of thesauri, because they have a semantic still considered weak, can be reused in the ontology. This is because ontologies require explicit relations between objects, properties, classes and individuals, as well as the declaration of axioms. In 2015, a work presents the semantic refinement of relationships in the structure of a thesaurus of the Agricultural area. (1) the results of the aforementioned work, (2) the literature on the conversion of thesauri into ontologies and (3) recommendations for the construction of thesauri and ontologies, this article explores the question about the reuse of structured knowledge In the structure of thesauri in the construction of ontologies. The results point out that the semantically refined relationships in the thesaurus structure can be better used in the creation of ontologies, but that there is no perfect correlation. In Information Science, this study contributes because it brings inputs to a greater understanding about the similarities and structural differences between thesauri and ontologies for reuse of knowledge.
