Truth Discovery and Copying Detection in a Dynamic World

Summary: Dynamic, time-evolving data with copying; models source quality (coverage, exactness, freshness) and uses an HMM to infer copy relations and timing. Bayesian aggregation yields true values and their evolution; demonstrates accuracy and scalability on real and synthetic data. (summarized by gpt-5-nano on Feb 09 2026)
