PFN-PT: a Framenet annotator for Portuguese ; Anotação semântica automática: um novo Framenet para o português
In: Domínios de Lingu@gem; Ahead of Print ; 1980-5799 (2022)
Abstract: This article presents PFN-PT, a robust system for the automatic semantic annotation of Portuguese, consisting of a new, parsing-oriented framenet and a rule-based frame- and role-tagger. The framenet provides almost 13,000 valency frames covering 7,300 verb lemmas with 10,700 senses. Frame and role tagging is achieved by iterated matching of syntactic structures and semantic noun types with slot-filler conditions in the framenet. We discuss design principles and present frame and role statistics. In an evaluation run on news data, the system achieved an overall F-score of 92.2% for frame senses. ; Este artigo apresenta o PFN-PT, um sistema robusto para a anotação semântica automática de Português, consistindo numa nova framenet com foco em parsing, e um tagger para frames e papéis semânticos baseado em regras. A framenet contêm cerca de 13.000 padrões sintáticos cobrindo 7.300 lemas verbais com 10.700 sentidos. A etiquetagem é realizada por meio de um alinhamento iterativo de estruturas sintáticas e classe semântica de substantivos com as condições listadas no framenet para argumentos sintáticos. Discutimos princípios de desenho e apresentamos estatísticas de distribuição de categorias. Numa avaliação realizada com base em textos jornalísticos, o sistema alcançou 92,2% sentidos/frames corretos para verbos.
