About

VerbAtlas is a hand-crafted lexical-semantic resource whose goal is to bring together all verbal synsets from BabelNet into semantically-coherent frames. The frames define a common, prototypical argument structure while at the same time providing new concept-specific information. VerbAtlas comes with an explicit, cross-frame set of semantic roles linked to selectional preferences expressed in terms of BabelNet synsets, and is the first resource enriched with semantic information about implicit, shadow, and default arguments.

This website provides:

• a web interface for looking up terms and Prototypical Argument Structures (with hyperlinks pointing to BabelNet);
• statistics, a bibliography and a download section.

IMPLICIT ARGUMENTS

Arguments implicit in the argument structure of the verb but not always syntactically expressed. Consider the synset {overleap, vault} in our JUMP frame: since its gloss is "Jump across or leap over (an obstacle)", we know that the Patient of this verb can be a hyponym of {obstacle}, therefore implying a selectional preference on the role with the {obstacle} synset.

SHADOW ARGUMENTS

Arguments incorporated in the meaning of the verb but not syntactically expressed. An example from the EAT-BITE frame is {eat in, dine in} ("Eat at home"). This synset is tagged with the shadow argument Location = {home}, since the latter is not expressed syntactically.
