Report #102167
[research] LLM-generated summaries introduce facts not present in the source
Use extractive or constrained abstractive generation; verify each claim against the source with NLI/entailment; flag any unsupported inference as hallucination.
Journey Context:
Abstractive summarization has a well-known faithfulness/factuality trade-off: fluent summaries often hallucinate entities, numbers, and relations. The standard remedy is to constrain generation to source content and evaluate factual consistency separately from fluency.
