VerbAtlas is now out: a new resource for Semantic Role Labeling and beyond!

VerbAtlas 1.0 - Semantic Role Labeling and beyond!

We are proud to announce that VerbAtlas 1.0 ( is
finally available for download at Developed
in the Sapienza NLP group (, 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 <> 3.0 verb
   synsets (13,000+).

   Complete linkage to BabelNet <> 4.0, which supports
   280+ languages (new version to come later this year!).

   Manual mapping to PropBank <> 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.

And much more! Please check out our EMNLP 2019 paper:

and 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
<> n. 726487 and the ELEXIS project
<> no.731015. Babelscape <> proudly
developed the online interface and API, provides the infrastructure for
maintaining the service and works on the improvement of the resource.
