A Grounded and Decomposed Framework for Relation-Level Hallucination Evaluation in Abstractive Summarization

Praveen Kumar Katwe, Rakesh Chandra Balabantaray, Kali Prasad Vittala +1

Abstractive text summarization systems frequently generate fluent yet unfaithful summaries by fabricating or distorting relationships between entities and events. Such relation-lev…

Abstractiveness Metrics for Evaluating Text Summarization: A Refined Formulation with Empirical Validation

Praveenkumar Katwe, Rakesh Chandra Balabantaray, Kali Prasad Vittala

Quantifying abstractiveness in generated summaries is essential for evaluating summarization models beyond surface-level metrics like ROUGE. We introduce Reference Abstraction (RA)…

Reducing Hallucinations in Summarization via Reinforcement Learning with Entity Hallucination Index

Praveenkumar Katwe, Rakesh Chandra, Balabantaray Kali +1

Reducing hallucinations in abstractive summarization remains a critical challenge for deploying language models (LMs) in real-world settings. In this work, we introduce a rewarddri…
