Semantic-Eval : A Semantic Comprehension Evaluation Framework for Large Language Models Generation without Training

ACL 2025long

With the increasing prominence of large language models (LLMs), evaluating their text-generation capabilities has become an essential research challenge. Although LLM-based evaluation methods exhibit robust performance, the inherent stochastic nature of the LLM generation process introduces a degree…
