Evaluating text summarization, especially when generated by Large Language Models (LLMs), presents challenges due to the complexity of summarization quality, which is often influenced by the summary's context and intended purpose. Traditional metrics like ROUGE, METEOR, and BLEU, which focus on N-gram overlap, fall short in capturing semantic meaning and context, highlighting the need for more robust methods like BERTScore and G-Eval that evaluate semantic similarity and coherence. Despite advancements, a gold standard for summarization evaluation remains elusive, and current metrics struggle with issues like factual consistency, logical flow, and critical information inclusion. The field is ripe for further research, particularly given the growing integration of LLMs into sectors like journalism and business intelligence, where accurate and reliable summarization is crucial.
