Still Loading@DravidianLangTech 2026: Telugu Prompt-Style Recovery using Multilingual Transformers
Summary
The "Still-Loading" team developed a system for the Telugu Prompt-Style Recovery shared task at DravidianLangTech@ACL 2026, aiming to categorize Telugu transcript passages into one of nine communicative styles: Formal, Informal, Optimistic, Pessimistic, Humorous, Serious, Inspiring, Authoritative, and Persuasive. Their approach involved comparing several multilingual Transformer-based models, specifically MuRIL, XLM-RoBERTa-Large, mBERT, and IndicBERTv2. The system incorporated a "Turbo Sandwich" preprocessing strategy, designed to emphasize lexical deltas, alongside Focal Loss. Ultimately, their MuRIL-based system secured 7th place on the official leaderboard, achieving a Macro-F1 rating of 0.1703. The source code for their experiments is publicly available.
Key takeaway
For NLP Engineers developing text classification systems for low-resource languages like Telugu, consider evaluating multilingual Transformer models such as MuRIL. Your approach should integrate specialized preprocessing, like the "Turbo Sandwich" strategy, to highlight crucial lexical features. Additionally, applying Focal Loss can enhance model performance, especially when dealing with imbalanced style categories. This strategy offers a practical pathway for improving prompt-style recovery in similar linguistic contexts.
Key insights
Multilingual Transformers, combined with specific preprocessing, can classify Telugu communicative styles.
Principles
- Multilingual Transformers are viable for low-resource languages.
- Lexical deltas can be emphasized for style classification.
- Focal Loss can improve classification performance.
Method
The method involved comparing MuRIL, XLM-RoBERTa-Large, mBERT, and IndicBERTv2, applying a "Turbo Sandwich" preprocessing strategy to highlight lexical deltas, and using Focal Loss for training.
In practice
- Use MuRIL for Telugu text classification tasks.
- Implement "Turbo Sandwich" for lexical emphasis.
- Apply Focal Loss in imbalanced classification.
