OpenWordNet-PT: A project report

This paper presents OpenWordNet-PT, a freely available open-source wordnet for Portuguese, with its latest developments and practical uses. We provide a detailed description of the RDF representation developed for OpenWordnet-PT. We highlight our efforts to extend the coverage of our resource and add nominalization relations connecting nouns and verbs. Finally, we present several real-world applications where OpenWordnet-PT was put to use, including a large-scale high-throughput sentiment analysis system.
