Verification

Verification is the process of determining whether a claim, statement, or assertion is true or false by checking it against evidence, sources, or external facts. In the context of misinformation research, verification encompasses both automatic methods (fact-checking using NLP and information retrieval) and human-based verification workflows.

Scope

• Claim-level verification: Determining the truth value of individual claims extracted from text.
• Evidence retrieval and ranking: Finding relevant evidence documents to support or refute a claim.
• Evidence integration: Combining multiple sources of evidence to reach a conclusion about claim veracity.
• Verification protocols: Formal procedures and frameworks (like Publication Authority) that structure verification workflows.

Key papers

• Kekatos et al. (2026) — SoK: Formal Methods for Fact-Checking and Information Integrity — Systematic survey of formal verification methods applied to fact-checking; proposes five-level assurance stack and identifies which formal techniques (SMT, model checking, proof-producing methods) apply at each level; discusses gap between formal guarantees and deployed systems.
• Making AI-Assisted Claims Independently Challengeable: Publication Authority and a Protocol for Falsifiable Publication Records — formalizes how evidence, measurement, authorization, and lifecycle must be bound to ensure claims remain verifiable and challengeable
