Fusing Data with Correlations

Summary: Models correlations among sources beyond simple copying (positive/negative, cross-domain, extractor rules) to improve truth discovery in web-harvested data. Evaluated on three real/synthetic datasets, it outperforms state-of-the-art methods by robustly fusing noisy, conflicting web data. (summarized by gpt-5-nano on Feb 09 2026)
