Challenge: Existing approaches to multilingual text detoxification are hampered by the scarcity of parallel multilingual datasets.
Approach: They propose a pipeline for the generation of multilingual parallel detoxification data and a dataset for SynthDetoxM which is manually generated and rewritten with open-source LLMs.
Outcome: The proposed pipeline outperforms human-annotated datasets even in data limited setting.
