A quick guide to Amazon’s 30+ papers at NAACL 2024

Although work involving large language models predominates, classical and more-general techniques remain well represented.

In recent years, the fields of natural-language processing and computational linguistics, which were revolutionized a decade ago by deep learning, were revolutionized again by large language models (LLMs). Unsurprisingly, work involving LLMs, either as a subject of inquiry themselves or as tools for other natural-language-processing applications, predominates at this year’s meeting of the North American Chapter of the Association for Computational Linguistics (NAACL). This paper guide sorts Amazon’s NAACL papers into those that deal explicitly with LLMs and those that don’t — although in many cases, the ones that don’t present general techniques or datasets that could be used with either LLMs or more-traditional models.
