Abstract
Previous evaluations of large language models (LLMs) focused on the perspective of various tasks or abilities. In this paper, we propose to evaluate from a linguistic viewpoint and argue that morpheme, a potential linguistic feature that captures both word-formation and lexical semantics, is another suitable component for evaluation that remains largely unexplored. In light of this, we construct MorphEval, a morpheme-informed benchmark, including three datasets following the bottom-up levels of characters, words, and sentences in Chinese, and then evaluate representative LLMs with both zero- and few-shot settings under two metrics. From this perspective, we reveal three aspects of issues LLMs nowadays encounter: dysfunctions in morphology and syntax, challenges with the long-tailed distribution of semantics, and difficulties from cultural implications. In these scenarios, even a smaller Chinese-targeted model may outperform ChatGPT, highlighting the actual challenges LLMs face and the necessity of language-specific improvements when applied to non-English languages. This new approach could also help guide model enhancements as well as get extended to other languages.- Anthology ID:
