Construction of a taxonomy for medieval Portuguese history: problems and challenges

Our main goal was to design and build a taxonomy of medieval Portuguese history using an interdisciplinary approach based on doctoral research. First, the criteria used for the selection of the vocabulary and its formal and semantic normalization were determined. Then species were listed, followed by the characterization of categories and their respective subclasses. As conclusions we highlight the successful application of the selected terms, as well as the fact that the taxonomy's categories are being continuously updated and expanded, both in their global extension and in the depth of their thematic representation. In addition we offer proposals for continuing the ontological development of this taxonomy.
