Abstract

Introduction: This paper presents a study of ontologies based on the Discursive Semiotics theoretical framework. An ontology was developed based on this perspective, making it possible to analyze the advantages and disadvantages of this model. From the developed ontology, it was investigated how the concepts (classes) of an ontology are formed with regard to the bias of the developer, the ontologist, subject inserted in a given socio-historical-ideological reality. Objective: To understand, using Discursive Semiotics, how social, historical and ideological elements can be recognized and explained in the representation of a knowledge domain through an ontology. Methodology: A bibliographical and descriptive research was carried out in which, based on the studied theoretical framework, an ontology was elaborated based on Discursive Semiotics – called semiological ontology. This ontology, because of its theoretical foundation, was constructed in a different way from that used in “traditional” ontologies, specifically as regards the formation of the axioms that characterize the concepts. Results: Due to its differentiated structure, the semiological ontology allowed a way to explain the conditions of discursive production – socio-historicalideological conditions – present in the representation of a domain. Conclusions: It was concluded that although semiological ontology is not as efficient, considering the requirements that an ontology must meet, this type of ontology can help in the investigation of important issues for the representation of information and knowledge, especially regarding the discourse conveyed, even indirectly, by the Knowledge Organization Systems (KOS).
