Detection of Homophobia and Transphobia in social media comments serves as an important step in the overall development of Equality, Diversity and Inclusion (EDI). In this research, we describe the system we formulated while participating in the shared task of Homophobia/ Transphobia detection as a part of the Fourth Workshop On Language Technology For Equality, Diversity, Inclusion (LT-EDI- 2024) at EACL 2024. We used an ensemble of three state-of-the-art multilingual transformer models, namely Multilingual BERT (mBERT), Multilingual Representations for Indic Languages (MuRIL) and XLM-RoBERTa to detect the presence of Homophobia or Transphobia in YouTube comments. The task comprised of datasets in ten languages - Hindi, English, Telugu, Tamil, Malayalam, Kannada, Gujarati, Marathi, Spanish and Tulu. Our system achieved rank 1 for the Spanish and Tulu tasks, 2 for Telugu, 3 for Marathi and Gujarati, 4 for Tamil, 5 for Hindi and Kannada, 6 for English and 8 for Malayalam. These results speak for the efficacy of our ensemble model as well as the data augmentation strategy we adopted for the detection of anti-LGBT+ language in social media data.

Content and trigger warnings give information about the content of material prior to receiving it and are used by social media users to tag their content when discussing sensitive topics. Trigger warnings are known to yield benefits in terms of an increased individual agency to make an informed decision about engaging with content. At the same time, some studies contest the benefits of trigger warnings suggesting that they can induce anxiety and reinforce the traumatic experience of specific identities. Our study involves the analysis of the nature and implications of the usage of trigger warnings by social media users using empirical methods and machine learning. Further, we aim to study the community interactions associated with trigger warnings in online communities, precisely the diversity and content of responses and inter-user interactions. The domains of trigger warnings covered will include self-harm, drug abuse, suicide, and depression. The analysis of the above domains will assist in a better understanding of online behaviour associated with them and help in developing domain-specific datasets for further research

Event detection, specifically in the socio-political domain, has posed a long-standing challenge to researchers in the NLP domain. Therefore, the creation of automated techniques that perform classification of the large amounts of accessible data on the Internet becomes imperative. This paper is a summary of the efforts we made in participating in Task 1 of CASE 2022. We use state-of-art multilingual BERT (mBERT) with further fine-tuning to perform document classification in English, Portuguese, Spanish, Urdu, Hindi, Turkish and Mandarin. In the document classification subtask, we were able to achieve F1 scores of 0.8062, 0.6445, 0.7302, 0.5671, 0.6555, 0.7545 and 0.6702 in English, Spanish, Portuguese, Hindi, Urdu, Mandarin and Turkish respectively achieving a rank of 5 in English and 7 on the remaining language tasks.
