A revised preprint on arXiv examines how the structure of a lexicon relates to the compositional way sentence meanings are built from word meanings. The author notes that much existing work on semantic universals assumes either fixed signal structures in lexicons or holistic composition that cannot be interpreted. The work frames these questions within evolutionary semantics.
A new arXiv paper examines how word meanings in Sinhala have shifted over long historical periods, focusing on a language with limited textual resources. The authors tackle obstacles such as sparse historical corpora and the drawbacks of static embedding alignment techniques when measuring semantic drift. The work contributes an evaluation approach for diachronic semantic change in low-resource NLP settings.
A new arXiv paper argues that an AI system's output should not be read as a description of a fact or world state, but as an engineered representation. The authors propose a semantic framework for describing such systems so their representations can be checked for correctness. The work is a conceptual contribution rather than a model release or benchmark.
