Evaluating Abstractive Summarization (Chunk 4)
While ROUGE and similar metrics, such as BLEU and METEOR, offer quantitative measures, they often fail to capture the true essence of a well-generated summary. They also correlate worse with human scores. Given the advancements in LLMs, which are adept at producing fluent and coherent summaries, traditional metrics like ROUGE may inadvertently penalize these models. This is especially true if the summaries are articulated differently but still encapsulate the core information accurately.
