CUET-2567@DravidianLangTech-ACL 2026: Multimodal Stance and Target Identification in Dravidian Political Memes
Summary
A multilevel multimodal framework for political meme classification in Tamil and Malayalam was proposed as part of the Multi Level Political Meme ClassificationDravidianLangTech@ACL 2026 shared task. This framework addresses two classification levels: Level 1 identifies meme stance as either Troll/Oppose or Support/Praise, while Level 2 determines the specific target category, such as Individual, Party, or Intersection. Researchers evaluated both unimodal and multimodal architectures, confirming the superior effectiveness of combining image and text features for meme understanding. The mBERT+ViT architecture demonstrated the best overall performance across both languages and classification levels. In the shared task, the framework achieved an average F1 score of 0.72, securing 2nd rank in Malayalam, and an F1 score of 0.76, securing 6th rank in Tamil. However, their own experimental evaluation yielded F1 scores of 0.62 for Tamil and 0.49 for Malayalam, with challenges attributed to dataset size, class imbalance, and noisy text extraction.
Key takeaway
For NLP engineers developing sentiment or stance analysis systems for low-resource languages, you should prioritize multimodal architectures. Your models, especially those using mBERT+ViT, will achieve better performance in classifying complex political memes by integrating both visual and textual cues. Be prepared to address challenges like dataset size and class imbalance to improve real-world F1 scores beyond initial benchmarks.
Key insights
Multimodal approaches combining text and image are crucial for accurate political meme classification in Dravidian languages.
Principles
- Multimodal analysis outperforms unimodal for meme understanding.
- Stance and target identification require multi-level classification.
- Dataset limitations impact model performance.
Method
A multilevel multimodal framework classifies political memes in Tamil and Malayalam. Level 1 identifies stance (Troll/Oppose, Support/Praise), and Level 2 determines target (Individual, Party, Intersection) using mBERT+ViT.
In practice
- Combine mBERT and ViT for multimodal meme analysis.
- Address class imbalance in meme datasets.
- Improve text extraction from noisy meme images.
