Information quality assessment

Evaluation of the credibility, accuracy, and trustworthiness of information sources and claims. Information quality assessment operates at multiple levels: source-level (Is this news outlet reliable?), claim-level (Is this statement true?), and network-level (What proportion of a user's information diet is from credible vs. questionable sources?). Methods include domain reputation scoring, semantic analysis of claims, and citation network analysis.
