ssn_diBERTsity@LT-EDI-EACL2021: Hope Speech Detection on multilingual YouTube comments via transformer based approach

摘要

In recent times, there exists an abundance of research to classify abusive and offensive texts focusing on negative comments but only minimal research using the positive reinforcement approach. The task was aimed at classifying texts into 'Hope_speech', 'Non_hope_speech', and 'Not in language'. The datasets were provided by the LT-EDI organisers in English, Tamil, and Malayalam languages with texts sourced from YouTube comments. We trained our data using transformer models, specifically mBERT for Tamil and Malayalam and BERT for English, and achieved weighted average F1-scores of 0.46, 0.81, 0.92 for Tamil, Malayalam, and English respectively. In the task results, our approach ranked second, fourth and fourteenth place in English, Malayalam and Tamil respectively.
