Study Finds Affixal Negation Cues Improve Language Model Negation Understanding
A new arXiv paper argues that research on negation in language models has focused too narrowly on a few common single-word cues such as "not" and "never". The authors examine a wider range of negation signals and report that affixal negations, formed through prefixes and suffixes, lead to better negation understanding than the cues usually studied. The work points to broader cue coverage as a way to address a persistent weakness in both LMs and LLMs.
