Catalogación de Recursos Educativos utilizando Vocabulario Controlado a partir de Ontologías

Resumo

This paper presents a document indexer system by using controlled vocabulary represented by ontologies. This cataloguer can assist the upload of educational resources in a repository, providing their keywords. In this first proposal, the domain of interest for the classification is Computer Science and ontologies were developed for three of its areas using Methontology methodology. The system architecture is presented and a prototype is implemented in Java, using a keyword extractor and an algorithm that searches for terms that are keywords and are within the ontology, using as parameters the weights of the term in the document and in the ontology. The functionality of this prototype is illustrated by a case study.
