OpenWordNet-PT (de Paiva et al., 2012) abbreviated to OpenWN-PT, is a wordnet originally developed as a Portuguese projection of the Universal WordNet (UNW). Its long-term goal is to serve as the main lexicon for a NLP system focusing on deep logical reasoning with emphasis on representation of knowledge, exploring mappings to ontologies such as SUMO. OpenWN-PT has constantly been improved through linguistically motivated additions, either manually or from evidence in large corpora.
