Summary Consistency

Measure whether summaries stay faithful to the original text. Spot inconsistencies and improve alignment with source content.

Objective:

Summary Consistency evaluates the factual alignment between the generated summary and the source content. It checks if the summary maintains the same facts, figures, and core messages as the input without introducing any hallucinations or errors. This metric is crucial for ensuring that no factual distortions occur when compressing the information.
