Evaluating Text Summaries Generated by Large Language Models Using OpenAI's GPT

Central Theme

This research evaluates OpenAI's GPT models as evaluators of summaries from six transformer-based models (DistilBART, BERT, ProphetNet, T5, BART, and PEGASUS) using metrics like ROUGE, LSA, and GPT's own assessment. GPT demonstrates strong correlations, particularly in relevance and coherence, suggesting its potential as a valuable tool for evaluating text summaries. The study assesses models' performance on the CNN/Daily Mail dataset, with a focus on conciseness, relevance, coherence, and readability. Findings highlight the need for integrating AI-driven evaluations like GPT to refine assessments in natural language processing tasks and suggest future research directions, including expanding to diverse NLP tasks and understanding human perception of AI-generated evaluations.
