Evaluating GPT-3.5 and GPT-4 on Grammatical Error Correction for Brazilian Portuguese (2306.15788v2)

Abstract: We investigate the effectiveness of GPT-3.5 and GPT-4, two LLMs, as Grammatical Error Correction (GEC) tools for Brazilian Portuguese and compare their performance against Microsoft Word and Google Docs. We introduce a GEC dataset for Brazilian Portuguese with four categories: Grammar, Spelling, Internet, and Fast typing. Our results show that while GPT-4 has higher recall than other methods, LLMs tend to have lower precision, leading to overcorrection. This study demonstrates the potential of LLMs as practical GEC tools for Brazilian Portuguese and encourages further exploration of LLMs for non-English languages and other educational settings.
