Evaluating Semantic Relation Knowledge through Bidirectional Relation Prediction from Gloss Pairs

A challenging task in which an LLM predicts the relation between two glosses (definitions of senses) presented in two different orders, suggesting limitations in current LLMs's semantic relation knowledge, both in identifying relations and in respecting asymmetry.

Cross-Lingual Representation Alignment by Token-Level Optimal Transport in a Language-Agnostic Space

This work proposes CAROT (Cross-Lingual Alignment of Representations in a Language-Agnostic Space via Optimal Transport), which consists of identifying language-specific representations in LLMs'internal states and aligning language-agnostic representations across languages at the token level by optimal transport, while...

Relation Geometry in Semantic Space of Language Models

The results empirically show that relation geometry is not equally well-represented for all relations in semantic space, suggesting that there is a difference in how well semantic relations might be learned from distributional information alone.
