© 2018 Sociedad Española para el Procesamiento del Lenguaje Natural. The main aim of this project is to create a tool for the automatic annotation of factuality expressed in Spanish texts. We intend the representation to be very rich, so it will be carried out from three different perspectives: multilevel, multidimensional and multitextual. The multilevel analysis gives account of the various linguistic markers that express the degree of certainty of an event at the morphological and syntactic, as well as discourse, levels. The multidimensional analysis accounts for the varied number of voices that assess an event. Finally, the multitextual analysis will take into account the various texts about the same event, which is one of the most innovative aspects of our proposal.
