Building a Hybrid Summary Evaluation Framework

Combining deterministic NLP with LLM-as-Judge for robust evaluation Summary Evaluation Challenges Summary evaluation metrics sometimes fall short in capturing the qualities most relevant to assessing summary quality. Traditional machine learning for natural language processing (NLP) has covered a lot of ground in this area. Widely used measures such as ROUGE focus on surface-level token overlap and n-gram matches. While effective for evaluating lexical similarity, these approaches offer limited insight into aspects such as factual accuracy or semantic completeness [1]. ...
