TAMILGOODBADTXT@DravidianLangTech 2026:A Multilingual Transformer-Based Approach for Abusive Language Identification in Tamil Social Media
Summary
Varalakshmi K and Bharathi B, in their 2026 paper "TAMILGOODBADTXT@DravidianLangTech 2026:A Multilingual Transformer-Based Approach for Abusive Language Identification in Tamil Social Media," introduce a multilingual transformer-based method for identifying abusive language in Tamil social media. Detecting such content is challenging in low-resource languages like Tamil due to prevalent spelling errors, informal expressions, and code-mixing. Their proposed general pipeline utilizes a pretrained XLM-RoBERTa model to extract contextual and semantic representations from input text, followed by preprocessing, tokenization, and binary classification into abusive or non-abusive categories. Experiments conducted on Tamil social media datasets demonstrated that this approach achieved an F1-score of 78.64%, highlighting the effectiveness of cross-lingual pretrained models for abusive language detection in low-resource linguistic contexts.
Key takeaway
For NLP Engineers developing content moderation systems for low-resource languages, this research suggests adopting multilingual transformer models. Your efforts to detect abusive language in contexts like Tamil social media can benefit significantly from pretrained models such as XLM-RoBERTa, which achieved an F1-score of 78.64%. Consider integrating a preprocessing, tokenization, and binary classification pipeline to address challenges like code-mixing and informal expressions effectively.
Key insights
Multilingual transformers effectively identify abusive language in low-resource social media, overcoming linguistic complexities.
