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:

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!
