SAUCE
A reference-free, fact-based evaluation method for dialogue summarization that uses textual entailment between the dialogue and the summary to verify each summary statement, thereby measuring both summary accuracy and factual coverage while supporting localization of hallucinations and omissions.

SAUCE stands for Summary Analysis Using Conversation Entailment, a reference-free, fact-based evaluation pipeline for dialogue summarization.
SAUCE simultaneously measures summary accuracy and factual coverage by judging whether the original dialogue supports the statements in the summary (entailment relations).
SAUCE is a reference-free method and does not require human-written reference summaries for comparison.
SAUCE decomposes the summary into atomic facts and performs entailment verification against the dialogue one by one, thereby breaking overall quality down into a traceable chain of evidence.
The study compared SAUCE with several popular summarization metrics, and the results show it is more effective at capturing information loss caused by transcription and translation errors and at identifying incomplete summaries.
Preliminary investigation shows that SAUCE is highly consistent with human judgment, but this conclusion remains preliminary in nature, and its stability awaits validation at larger scale and in more language scenarios.
SAUCE's interpretability lies in mapping summary scores to discrete, verifiable facts, allowing users to directly locate which specific sentence is a hallucination and which piece of information was omitted.
SAUCE's limitations include: entailment judgment depends on model capability, and the way facts are granularized affects results; moreover, open-source implementations and large-scale benchmark results have not yet been described in detail.
SAUCE is mainly aimed at cross-lingual conversational speech summarization, especially open-ended conversations that lack clear goals and contain considerable transcription and translation noise.
