Corpora The original 2015 QA-SRL dataset (He et al., 2015) was annotated by non-expert workers after completing a brief training procedure. In subsequent work, <cite>Fitzgerald et al. (2018)</cite> constructed a large-scale corpus and used it to train a <cite>parser</cite>. As both 2015 and <cite>2018 datasets</cite> use a single question generator, both struggle with maintaining coverage.
