  This paper describes the IUST NLP Lab submission to the Prompting Large
Language Models as Explainable Metrics Shared Task at the Eval4NLP 2023
Workshop on Evaluation & Comparison of NLP Systems. We have proposed a
zero-shot prompt-based strategy for explainable evaluation of the summarization
task using Large Language Models (LLMs). The conducted experiments demonstrate
the promising potential of LLMs as evaluation metrics in Natural Language
Processing (NLP), particularly in the field of summarization. Both few-shot and
zero-shot approaches are employed in these experiments. The performance of our
best provided prompts achieved a Kendall correlation of 0.477 with human
evaluations in the text summarization task on the test data. Code and results
are publicly available on GitHub.
