Análise ontolológica aplicada ao desenvolvimento de Frames

Abstract

Frame semantics is a theory that aims to establish the semantics of a lexical item by the evocation of the associated conceptual scene related to it. FrameNet is a lexical-semantic database developed according to the frame semantics frames and is constituted of a set of frames related by semantics links. The methodology for the discovery and incorporation of frames is based on semi-formal criteria and incorporates some ontological criteria. This article seeks to deepen this ontological analysis in order allow greater formalization of the process. We analyzed sentences from the "Corpus do Português" corpus containing the lexeme "viagem" and aligned the frame elements types with top ontologies. We detected the prototypical sense presented in FrameNet. Moreover, we identified the metaphorical use of the lexeme and its use in the transportation sense based on the distinction of the ontological type of agent. Thus, from the ontological analysis was possible to find a new frame yet to be included in the FrameNet database. Such evidence suggests possible benefits of the proposed methodology and may facilitate, in the future, a formal link in distinct frames motivated by the lexeme polysemy. We believe that this may establish better relations among frames, which can facilitate the automatic textual inference and the actual network usage by people.
