ONTOLOGIAS DE DOMÍNIO: ESTUDO DAS RELAÇÕES CONCEITUAIS E SUA APLICAÇÃO

摘要

Lack of theoretical bases and sound methodologies are problems that arise when building Ontologies. These constitute hindrance to the creation of inference rules for machine understanding. The study proposes systematization of relations found in the literature from Information Science, Terminology, Computer Science and Bioinformatics. Fundamental Categories in Information Science provide a domain representation model, but not the relation among them. In Computer Science relations are revealed, but not the context in which they occur. The systematization proposed aims at linking couple of categories (categorical relations) with relations properly (formal relations). A sample of definitions from Gene Ontology was analyzedudto identify relations already mentioned in the literature and/or new ones. Despite the models for definition in Gene Ontology not always relations could be easily identified. It is concluded that different relations may arise in different domains and that systematic definitions are fundamental for the establishment of formal relations.
