Publisher summary· verbatim

arXiv:2610.41855v1 Announce Type: new Abstract: While sentence embeddings are primarily designed for semantic generalization, their latent geometry implicitly encodes surface-level lexical properties, a relationship that remains poorly understood. Shallow pooling methods discard word order, while de
