Multilingual Lexical Simplification Pipeline (MLSP)

Multilingual Lexical Simplification Pipeline (MLSP)

Lexical simplification is the process of identifying complex words and replacing them with simpler alternatives. Previous shared tasks such as SemEval-2021 Task 1 Lexical Complexity Prediction (LCP) and TSAR-2022 considered sub-tasks such as complex word identification and lexical substitution in isolation. To fill this gap, we propose the Multilingual Lexical Simplification Pipeline (MLSP) shared task which will include multiple sub-tasks of the pipeline in a single shared task.

The Multilingual Lexical Simplification Pipeline (MLSP) shared task hosted at BEA 2024 provides participants with new annotated datasets in various languages.
