Portais do conhecimento de universidades: proposta de um quadro referencial para estabelecimento do potencial semântico

Abstract

The accumulation of documents available on the Web makes it difficult to information retrieve and efficient knowledge management. Traditional models of information retrieval are inadequate for effective and quick search, and the results are often numerous and irrelevant. With the advent of the Semantic Web it was possible the use of formal ontology as a model of web information retrieval that improves the quality of the information retrieved. Semantic portals are a Knowledge Management tool that offers greater capacity and speed of access to information relevant results. In this trend, the goal of the this research is propose minimum conditions necessary for the establishment potential of semantic portals, by mapping the use of ontology as a model of information retrieval. The research's locus included the portals of federal public universities in southern Brazil, starting from a comparative study between the Semantic Web features and the tools and technologies used in the institutions surveyed. The field research was instrumentalized by a pool, collecting data from the technical team responsible for portals. The main results were presented a diagnosis of ontology in the structuring of respondents university portals and a framework of minimum conditions for semantic potential property portals.
