This paper presents an overview of the Shared Task on detecting homophobia and transphobia in meme datasets across three languages: Hindi, English, and Chinese. With the rapid growth of internet users worldwide, memes have become a widely used medium for expressing humor, satire, and sarcasm on social media platforms. However, their increasing popularity has also facilitated the spread of hate, misinformation, and propaganda targeting specific communities. Hateful memes often attack individuals or groups based on attributes such as physical appearance, language, ethnicity, religion, or sexual orientation. Among those affected, the LGBTQ+ community is particularly vulnerable and frequently targeted on social media platforms. To address this issue, we organized a shared task that focuses on identifying homophobic and transphobic hate in memes. The task aims to encourage the development of automated systems capable of detecting such harmful content across multiple languages. Evaluation was conducted using Macro F1-score as the primary metric. The top performing system achieved a Macro F1-score of 0.8377 for English, 0.8081 for Hindi, and 0.7535 for Chinese, demonstrating promising results for multilingual hate detection in memes.

Political sentiment analysis aims to automatically identify opinions and attitudes expressed in political discourse on social media platforms. This paper presents an overview of the TamilPoliSent 2026 shared task on multiclass political sentiment analysis in Tamil, organized as part of DravidianLangTech@ACL 2026. The task focuses on categorizing Tamil comments from X (formerly Twitter) into seven sentiment classes: Substantiated, Sarcastic, Opinionated, Positive, Negative, Neutral, and None of the above. The dataset consists of 5,440 annotated Tamil tweets collected from political discussions on social media. Participants were provided with labeled training and development datasets, while the test set was used for final evaluation.A total of 22 teams participated in the shared task and explored a wide range of modeling approaches including classical machine learning methods, transformer-based architectures, hybrid lexical–contextual models, and ensemble frameworks. System performance was evaluated using Macro F1-score to ensure balanced evaluation across all sentiment categories. The best-performing system achieved a Macro F1-score of 0.3935.The results highlight several challenges in Tamil political sentiment analysis, including class imbalance, sarcasm, informal writing styles, and semantic overlap between sentiment categories. The shared task demonstrates that transformer-based models combined with class-balanced learning and hybrid representations are effective for handling fine-grained political sentiment classification in low-resource languages. These findings contribute to advancing research in political discourse analysis and natural language processing for Tamil and other under-resourced languages.

The rise and the intensity of harassment and hate speech in social media platforms against LGBTQ+ communities is a growing concern. This work is an initiative to address this problem by conducting a shared task focused on the detection of homophobic and transphobic content in multilingual settings. The task comprises two subtasks: (1) multi-class classification of content into Homophobia, Transphobia, or Non-anti-LGBT+ categories across eight languages and (2) span-level detection to identify specific toxic segments within comments in English, Tamil, and Marathi. This initiative helps the development of explainable and socially re- sponsible AI tools for combating identity-based harm in digital spaces. Multiple teams registered for the task, however only two teams submitted their results, and the results were evaluated using the macro F1 score.

Political multiclass detection is the task of identifying the predefined seven political classes. In this paper, we report an overview of the findings on the “Political Multiclass Sentiment Analysis of Tamil X(Twitter) Comments” shared task conducted at the workshop on DravidianLangTech@NAACL 2025. The participants were provided with annotated Twitter comments, which are split into training, development, and unlabelled test datasets. A total of 139 participants registered for this shared task, and 25 teams finally submitted their results. The performance of the submitted systems was evaluated and ranked in terms of the macro-F1 score.

This overview paper presents the findings of the Shared Task on Abusive Tamil and Malayalam Text Targeting Women on Social Media, organized as part of DravidianLangTech@NAACL 2025. The task aimed to encourage the development of robust systems to detectabusive content targeting women in Tamil and Malayalam, two low-resource Dravidian languages. Participants were provided with annotated datasets containing abusive and nonabusive text curated from YouTube comments. We present an overview of the approaches and analyse the results of the shared task submissions. We believe the findings presented in this paper will be useful to researchers working in Dravidian language technology.

This paper provides a comprehensive summary of the “Homophobia and Transphobia Detection in Social Media Comments” shared task, which was held at the LT-EDI@EACL 2024. The objective of this task was to develop systems capable of identifying instances of homophobia and transphobia within social media comments. This challenge was extended across ten languages: English, Tamil, Malayalam, Telugu, Kannada, Gujarati, Hindi, Marathi, Spanish, and Tulu. Each comment in the dataset was annotated into three categories. The shared task attracted significant interest, with over 60 teams participating through the CodaLab platform. The submission of prediction from the participants was evaluated with the macro F1 score.

Hope serves as a powerful driving force that encourages individuals to persevere in the face of the unpredictable nature of human existence. It instills motivation within us to remain steadfast in our pursuit of important goals, regardless of the uncertainties that lie ahead. In today’s digital age, platforms such as Facebook, Twitter, Instagram, and YouTube have emerged as prominent social media outlets where people freely express their views and opinions. These platforms have also become crucial for marginalized individuals seeking online assistance and support[1][2][3]. The outbreak of the pandemic has exacerbated people’s fears around the world, as they grapple with the possibility of losing loved ones and the lack of access to essential services such as schools, hospitals, and mental health facilities.

Our research aims to address the task of detecting homophobia and transphobia in social media code-mixed comments written in Spanish. Code-mixed text in social media often violates strict grammar rules and incorporates non-native scripts, posing challenges for identification. To tackle this problem, we perform pre-processing by removing unnecessary content and establishing a baseline for detecting homophobia and transphobia. Furthermore, we explore the effectiveness of various traditional machine-learning models with feature extraction and pre-trained transformer model techniques. Our best configurations achieve macro F1 scores of 0.84 on the test set and 0.82 on the development set for Spanish, demonstrating promising results in detecting instances of homophobia and transphobia in code-mixed comments.

We participated in the Sentiment Analysis in Tamil and Tulu - DravidianLangTech 2023-RANLP 2023 task in the team name of VEL. This research focuses on addressing the challenge of detecting sentiment analysis in social media code-mixed comments written in Tamil and Tulu languages. Code-mixed text in social media often deviates from strict grammar rules and incorporates non-native scripts, making sentiment identification a complex task. To tackle this issue, we employ pre-processing techniques to remove unnecessary content and develop a model specifically designed for sentiment analysis detection. Additionally, we explore the effectiveness of traditional machine-learning models combined with feature extraction techniques. Our best model logistic regression configurations achieve impressive macro F1 scores of 0.43 on the Tamil test set and 0.51 on the Tulu test set, indicating promising results in accurately detecting instances of sentiment in code-mixed comments.
