Researchers have investigated the geometric representation of semantic relations within the vector spaces of language models. Their study explored whether words related to a target word occupy similar regions and if these regions are distinct for different relations. The findings indicate that relata in asymmetric relations tend to cluster together more clearly than in symmetric ones, and the models partially encode properties like symmetry and transitivity. The research also highlighted that causal language models rely more on lexical information, while masked and diffusion models prioritize contextual information for relation geometry. AI
