Challenge: lexical simplification is the task of reducing lexically and/or structural complexity of texts.
Approach: They propose to collect manual simplifications for 1,100 original sentences using a sentence-level corpus from the Public Administration domain.
Outcome: The proposed corpus contains 1,100 original sentences with manual simplifications collected through a two-stage process.
