CuriousVectors@LT-EDI 2026: Detection of Homophobic and Transphobic Memes on Social Media Using a Hybrid Multimodal Approach

· Source: Paper Index on ACL Anthology · Field: Technology & Digital — Artificial Intelligence & Machine Learning, Data Science & Analytics · Depth: Expert, medium

Summary

The paper "CuriousVectors@LT-EDI 2026" introduces a hybrid multimodal approach designed to detect homophobic and transphobic memes circulating on social media platforms. This method directly addresses the growing issue of abusive and harmful content, specifically targeting the LGBT+ community through visual and textual meme formats. The proposed technique integrates both image and text information processing. To mitigate the challenge of limited data within the LT-EDI 2026 challenge dataset, the models underwent pre-fine-tuning on a similar external dataset named PrideMM. This multimodal strategy achieved notable results in the shared task, securing the 8th rank for English language memes with a Macro F1-score of 0.24, and the 6th rank for Chinese language memes, yielding a Macro F1-score of 0.57.

Key takeaway

For NLP Engineers and AI Scientists developing hate speech detection systems for social media, you should prioritize multimodal approaches, especially when dealing with meme content. Your models will benefit significantly from pre-fine-tuning on similar, larger datasets like PrideMM to address data scarcity challenges. This strategy can improve detection accuracy for nuanced content like homophobic and transphobic memes, enabling more effective content moderation.

Key insights

Hybrid multimodal AI detects homophobic/transphobic memes by pre-fine-tuning on similar datasets to overcome data scarcity.
