Knowledge-Based Trust: Estimating the Trustworthiness of Web Sources

Summary: Introduces Knowledge-Based Trust (KBT), a trust score for web sources based on factual correctness rather than link structure. Employs a multi-layer probabilistic model to jointly distinguish extraction errors from source-level errors, scaling to 2.8B facts over 119M pages with manual validation.
