Modality-Corpus

This repository contains the data used to evaluate the event-based modality task proposed by Pyatkin et al. (2021).

We use the Georgetown Gradable Modal Expressions Corpus (GME) as described by Rubinstein et al. (2013). The corpus is available for search through the ANNIS interface (please contact Prof. Paul Portner at Paul.Portner@georgetown.edu for access).

The GME Corpus was obtained by expert annotation of the documents included in the MPQA Opinion Corpus (Wiebe et al., 2005). Prior to downloading our data, you are required to first obtain access to the MPQA Corpus at https://mpqa.cs.pitt.edu/corpora/mpqa_corpus/

Our experiments used a subset of the GME annotations (specifically: modal triggers, associated propositional spans, and modal senses), pre-processed into the CoNLL-formatted file provided in this repository.
