Método de avaliação de ontologias através de alinhamento semiautomático baseado em visualização de informação

Abstract

The present work has as a major goal to develop an evaluation method based on ontology alignment and information visualization. This method aims to assist the correct construction of an ontology, based on the evaluation of its interoperability with a well established ontology in the field added to visual analysis of its structures and descriptions. In order to achieve this goal, some assessment and alignment processes and their technological support were developed. The processes are based on the high probability in which two ontologies possessing the same base and domain are inter-connecting, ie, there must be interoperability between them. These processes weredivided into three pillars: treatment, system, and evaluation, each representing an aspect of the evaluation method. The first is the process of treatment and evaluation, the second represents thetechnological support and the third represents the union of the first two pillars. An alignment and visualization system of ontologies modeled by OWL (Web Ontology Language), which is the second part of the evaluation method, was developed to support the evaluation method and ontology visualization. It is through the system that the analysis of structures, descriptions and alignment were done. This allows the consolidation of processes to occur by applying the third developed pillar. In conclusion, a presentation with the created processes and systems are shown, as well as a case study to investigate the methods applicability, and advantages.
