This paper serves as a solution for multi-label emotion classification and intensity for text, developed for SemEval-2025 Task 11. The method uses a fine-tuned RoBERTa-Large transformer model. The system represents a multi-label classification approach to identifying multiple emotions, and uses regression models to estimate emotion strength. The model performed with ranks of 31st and 17th place in the corresponding tracks. The findings show impressive performance and it remains possible to improve the performance of ambiguous or low-frequency emotion recognition using the state-of-the-art contextual embeddings and threshold optimization techniques.

The ACL shared task of DravidianLangTech-2022 for Troll Meme classification is a binary classification task that involves identifying Tamil memes as troll or not-troll. Classification of memes is a challenging task since memes express humour and sarcasm in an implicit way. Team SSN_MLRG1 tested and compared results obtained by using three models namely BERT, ALBERT and XLNET. The XLNet model outperformed the other two models in terms of various performance metrics. The proposed XLNet model obtained the 3rd rank in the shared task with a weighted F1-score of 0.558.

DepSign-LT-EDI@ACL-2022 aims to ascer-tain the signs of depression of a person fromtheir messages and posts on social mediawherein people share their feelings and emo-tions. Given social media postings in English,the system should classify the signs of depres-sion into three labels namely “not depressed”,“moderately depressed”, and “severely de-pressed”. To achieve this objective, we haveadopted a fine-tuned BERT model. This solu-tion from team SSN_MLRG1 achieves 58.5%accuracy on the DepSign-LT-EDI@ACL-2022test set.
