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 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 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 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. 

Enjoy!

From above introduction to VerbAtlas:

"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!)."

Sentence: "Nurses wear certified personal protective equipment to care for patients with Coronavirus." in VerbAtlas 1.0
