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 (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:

Semantic Resource and Its Application to Semantic Role Labeling

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!
