ASSET: ASSET (Alva-Manchego et al., 2020) is multi-reference dataset
for the evaluation of sentence simplification in English. The dataset
uses the same 2,359 sentences from TurkCorpus (Xu et al., 2016)
and each sentence is associated with 10 crowdsourced simplifications.
Unlike previous simplification datasets, which contain a single
transformation (e.g., lexical paraphrasing in TurkCorpus or sentence
splitting in HSplit), the simplifications in ASSET encompass a variety
of rewriting transformations.

TurkCorpus: TURKCorpus is a multi-reference dataset for the evaluation of
sentence simplification in English. The dataset consists of 2,359 sentences
from the Parallel Wikipedia Simplification (PWKP) corpus. Each sentence is
associated with 8 crowdsourced simplifications that focus on only lexical
paraphrasing (no sentence splitting or deletion).
