Uma investigação sobre a avaliação de modelagem conceitual baseada em ontologias: estudo de caso de modelos para sistemas de informação desenvolvidos na Universidade Federal de Minas Gerais

Abstract

Information Systems (IS) play an important role in current companies, which are subjected to increasing competitiveness and the dynamism of the market. To meet the needs for which they were planned, the IS should be based on consistent representations of knowledge domain in the field that they will act. In this context, the activity of modeling and their language of representation have important role. Models constructed in ad-hoc manner can result in inadequate representation, difficulties of communication between the developers and difficulties of integrationbetween systems. This research presents a case study, whose object of study consists of a set of models developed at UFMG for real organizations of state administration. It uses a reference ontology as a standard, comparing the constructs of language of representation to the constructs of the ontology. It develops a mapping between theelements of language and elements of the reference ontology, creating new modeling diagrams. Finally, it gets models developed under the principles of ontology, decreasing intuitive solutions and implementation-driven solutions. The research hopes to contribute to the development of appropriate IS, in terms of representation of reality, and open new paths for professionals in Information Science.
