Researchers audit Wikipedia data quality for low-resource NLP tasks

A new study has audited the quality of Wikipedia data for low-resource and multilingual Natural Language Processing (NLP) tasks. Researchers found significant quality issues, including script and language contamination, bot-generated content, and template articles, especially in non-English editions. Filtering this data improved language model performance in several scenarios, particularly for lower-quality language editions, suggesting a need for quality-aware best practices in NLP dataset curation.
