Multi-Stage Training for Abusive Comment Detection in Indic Languages
Summary
A research paper titled "Multi-Stage Training for Abusive Comment Detection in Indic Languages" (arXiv:2605.22380), authored by Pranshu Rastogi, Madhav Mathur, Ramaneswaran S, and Kshitij Mohan, introduces a novel pipeline for identifying abusive comments on social media. Submitted on May 21, 2026, this 4-page work specifically addresses content in Indic languages, where effective moderation is crucial given the widespread use of social platforms. The proposed system integrates language-based preprocessing with an ensemble of several machine learning models. Through extensive experimentation, the authors aim to minimize the false-positive rate, ensuring that non-abusive content is not incorrectly flagged. This approach seeks to balance effective abuse detection with the preservation of freedom of expression in online communication environments.
Key takeaway
For NLP Engineers developing content moderation systems for Indic languages, you should consider implementing a multi-stage training pipeline. This approach, combining language-based preprocessing with an ensemble of models, is shown to minimize false positives, which is critical for upholding freedom of expression. Prioritize rigorous evaluation of false positive rates to ensure your system effectively detects abuse without over-censoring.
