Factgrounded

Factgrounded is a term used in information grounding and natural language processing to describe the property of a statement, claim, or generated output being anchored to verifiable facts drawn from an admissible source, dataset, or document. In practice, a factgrounded system either retrieves relevant facts before producing text or checks generated content against trusted sources to ensure consistency with evidence. The concept sits within broader efforts to improve verifiability and reduce hallucinations in AI.

Origins and usage have grown with the rise of retrieval-augmented generation and knowledge-grounded dialogue systems. Factgrounded approaches emphasize transparent linkage between claims and supporting evidence, enabling users to trace conclusions to sources. This contrasts with purely generative models that may produce fluent but unsupported statements.

Common methods include retrieval-augmented generation, where a model accesses a knowledge base during response construction, and post-hoc fact-checking, where outputs are evaluated against external sources after generation. Some systems also attach explicit citations or evidence fragments to statements, supporting traceability and accountability.

Applications span customer support, research assistants, journalism tools, and educational chatbots, where reliability and traceability are critical. Challenges include source quality and coverage, latency from retrieval, handling conflicting evidence, and maintaining up-to-date information. Assessing grounding quality involves metrics for citation accuracy, source reliability, and the tractability of presenting verifiable evidence.

Factgrounded remains an evolving concept at the intersection of AI, information retrieval, and fact-checking, reflecting a general move toward more transparent and evidence-based automated text generation.
