Automatic lexical simplification is a task to substitute lexical items that
may be unfamiliar and difficult to understand with easier and more common
words. This paper presents MultiLS-SP/CA, a novel dataset for lexical
simplification in Spanish and Catalan. This dataset represents the first of its
kind in Catalan and a substantial addition to the sparse data on automatic
lexical simplification which is available for Spanish. Specifically, MultiLS-SP
is the first dataset for Spanish which includes scalar ratings of the
understanding difficulty of lexical items. In addition, we describe experiments
with this dataset, which can serve as a baseline for future work on the same
data.
