VerbAtlas is now out!
VerbAtlas 1.0 is now available for download at verbatlas.org
We are proud to announce that VerbAtlas 1.0 (http://verbatlas.org) is finally available for download. Developed at the Sapienza NLP group, the multilingual Natural Language Processing group at the Sapienza University of Rome, VerbAtlas is a novel large-scale manually-crafted semantic resource for wide-coverage, intelligible and scalable Semantic Role Labeling. The goal of VerbAtlas is to manually cluster WordNet synsets that share similar semantics into a set of semantically-coherent frames.The main features are:
- Full coverage of WordNet 3.0 verb synsets (13,000+).
- Complete linkage to BabelNet 4.0, which supports 280+ languages.
- Manual mapping to PropBank of all CoNLL-2009 and CoNLL-2012 dataset occurrences (5000+ mappings).
- 467 semantically-coherent frames using 26 cross-frame semantic roles for their argument structure.
- Selectional preferences: the superconcept most probably associated with a semantic role in a frame (e.g. food for the patient role of the EAT frame).
- Default/Shadow arguments: arguments logically implied or already incorporated in a verb.
- Implicit arguments: arguments that are implicit in the argument structure of a verb.
And much more! Please check out our EMNLP 2019 paper “VerbAtlas: a Novel Large-Scale Verbal Semantic Resource and Its Application to Semantic Role Labeling” or http://verbatlas.org for more details!
A state-of-the-art span-based SRL system which uses VerbAtlas and PropBank jointly is also available from the same website.
Kind regards, The Sapienza NLP group
