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
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
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.

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.
