NUEVO MODELO DE REPRESENTACIÓN DE TEXTOS: GRAFOS DE ASOCIACIÓN.

In this paper we present a new model, designated as association graph, to improve document representation, facilitating the ontological dimension. We explain how to create and use this kind of graph. Also, we analyze a document similarity measure based on this representation. A classical vector space model was used to evaluate this model and the similarity measure, investigating their strengths and weaknesses. The proposed model was found to give promising results.
