To compute these denotational similarities, we construct a denotation graph, i.e. a subsumption hierarchy over constituents and their denotations, based on a large corpus of 30K images and 150K descriptive captions.",

_DESCRIPTION = """\
SNLI-VE is the dataset proposed for the Visual Entailment (VE) task investigated in Visual Entailment Task for Visually-Grounded Language Learning accpeted to NeurIPS 2018 ViGIL workshop). 
SNLI-VE is built on top of SNLI and Flickr30K. The problem that VE is trying to solve is to reason about the relationship between an image premise Pimage and a text hypothesis Htext.

Specifically, given an image as premise, and a natural language sentence as hypothesis, three labels (entailment, neutral and contradiction) are assigned based on the relationship conveyed by the (Pimage, Htext)

entailment holds if there is enough evidence in Pimage to conclude that Htext is true.
contradiction holds if there is enough evidence in Pimage to conclude that Htext is false.
Otherwise, the relationship is neutral, implying the evidence in Pimage is insufficient to draw a conclusion about Htext.
