The Liar's Chatroom
Uncover the Deceiver in a 48-Hour AI & NLP Kaggle Challenge! About the Event Step into The Liar's Chatroom , a fast-paced 48-hour online Kaggle competition where NLP meets digital forensics! Participants will build an AI model to analyze fictional group-chat conversations, examine verified evidence, and identify which character is lying. Each conversation features four characters ( A, B, C, and D ), with exactly one character making a statement that contradicts the facts. Using a custom synthetic dataset, your mission is to train a model that spots contradictions with high accuracy. ️ Event Format & Dataset Dataset: Participants receive a custom synthetic dataset containing labeled training data and unlabeled test data. ️ Approach: You may use any Machine Learning or NLP approach—including custom architectures, pretrained models, LLMs, fine-tuning, or rule-based heuristics. Platform: Hosted externally on Kaggle . Rules & Regulations Team Size: Compete individually or in teams of up to 4 members . Submission Limit: Maximum of 5 submissions per team per day on Kaggle. Submission Format: Predictions must be uploaded in the prescribed CSV format before the deadline. Fair Play: Manual labeling of the test dataset and sharing predictions/code between competing teams are strictly prohibited . Code & Methodology Submission: Top-performing teams on th…
