VerbAtlas 1.0 - Semantic Role Labeling and beyond! We are proud to announce that VerbAtlas 1.0 (http://verbatlas.org) is finally available for download at http://verbatlas.org/download. Developed in the Sapienza NLP group (http://nlp.uniroma1.it), the multilingual Natural Language Processing research team 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 sets of semantically-coherent frames. The main features are: - 466 semantically-coherent frames using 26 cross-frame VerbNet-inspired semantic roles for their argument structure. - Available both for download and via RESTful API. - Full coverage of WordNet <https://wordnet.princeton.edu/> 3.0 verb synsets (13,000+). - Complete linkage to BabelNet <https://babelnet.org> 4.0, which supports 280+ languages (new version to come later this year!). - Manual mapping to PropBank <https://propbank.github.io/> of all CoNLL-2009 and CoNLL-2012 dataset occurrences (5000+ mappings). - 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 into 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: A. Di Fabio, S. Conia, R. Navigli “VerbAtlas: a Novel Large-Scale Verbal Semantic Resource and Its Application to Semantic Role Labeling <https://www.aclweb.org/anthology/D19-1058/>”, EMNLP-IJCNLP 2019, pp. 627-637 and 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 (just type a sentence!). VerbAtlas is an output of the MOUSSE ERC Consolidator Grant <http://mousse-project.org/> n. 726487 and the ELEXIS project <https://elex.is> no.731015. Babelscape <http://babelscape.com> proudly developed the online interface and API, provides the infrastructure for maintaining the service and works on the improvement of the resource. Enjoy!
