English WordNet 2020: Improving and Extending a WordNet for English using an Open-Source Methodology
John Philip McCrae | Alexandre Rademaker | Ewa Rudnicka | Francis Bond
Proceedings of the LREC 2020 Workshop on Multimodal Wordnets (MMW2020)

WordNet, while one of the most widely used resources for NLP, has not been updated for a long time, and as such a new project English WordNet has arisen to continue the development of the model under an open-source paradigm. In this paper, we detail the second release of this resource entitled “English WordNet 2020”. The work has focused firstly, on the introduction of new synsets and senses and developing guidelines for this and secondly, on the integration of contributions from other projects. We present the changes in this edition, which total over 15,000 changes over the previous release.

Inclusion of Lithological terms (rocks and minerals) in The Open Wordnet for English
Alexandre Tessarollo | Alexandre Rademaker
Proceedings of the LREC 2020 Workshop on Multimodal Wordnets (MMW2020)

We extend the Open WordNet for English (OWN-EN) with rock-related and other lithological terms using the authoritative source of GBA’s Thesaurus. Our aim is to improve WordNet to better function within Oil & Gas domain, particularly geoscience texts. We use a three step approach: a proof of concept-level extension of WordNet, a major extension on which we evaluate the impact with positive results and a full extension encompassing all GBA’s lithological terms. We also build a mapping to GBA which also links to several other resources: WikiData, British Geological Survey, Inspire, GeoSciML and DBpedia.

Semantic Links for Portuguese
Fabricio Chalub | Livy Real | Alexandre Rademaker | Valeria de Paiva
Proceedings of the Tenth International Conference on Language Resources and Evaluation (LREC'16)

This paper describes work on incorporating Princenton’s WordNet morphosemantics links to the fabric of the Portuguese OpenWordNet-PT. Morphosemantic links are relations between verbs and derivationally related nouns that are semantically typed (such as for tune-tuner ― in Portuguese “afinar-afinador” – linked through an “agent” link). Morphosemantic links have been discussed for Princeton’s WordNet for a while, but have not been added to the official database. These links are very useful, they help us to improve our Portuguese WordNet. Thus we discuss the integration of these links in our base and the issues we encountered with the integration.

NomLex-PT: A Lexicon of Portuguese Nominalizations
Valeria de Paiva | Livy Real | Alexandre Rademaker | Gerard de Melo
Proceedings of the Ninth International Conference on Language Resources and Evaluation (LREC'14)

This paper presents NomLex-PT, a lexical resource describing Portuguese nominalizations. NomLex-PT connects verbs to their nominalizations, thereby enabling NLP systems to observe the potential semantic relationships between the two words when analysing a text. NomLex-PT is freely available and encoded in RDF for easy integration with other resources. Most notably, we have integrated NomLex-PT with OpenWordNet-PT, an open Portuguese Wordnet.
