Compositionality and the lexicon in evolutionary semantics

Formal semantics has shown that sentence meanings arise by recursively composing lexical meanings, yet much of the literature on semantic universals models either lexicons with fixed signal structures or holistic composition without interpretable lexical parts. We introduce a framework that integrates this fundamental insight of formal semantics in evolutionary modeling, by allowing lexical meanings and a composition function to co-evolve under pressures for conceptual simplicity and communicative accuracy.

Factors Influencing the Emergence of Dependency Length Minimization in Neural Agent Simulations

The study explores how neural agents develop dependency length minimization (DLM) in artificial languages using a recurrent neural network framework. By manipulating processing constraints such as listening noise, speaker capacity, and incremental sentence processing, the researchers find that DLM emerges only under incremental processing pressure, while other factors produce varied word‑order preferences. These results suggest that human cognitive processing limits may influence the emergence of DLM in language.

Exposure is Optional: Learning Unlike Coordination in Language Models

Coordination, a fundamental linguistic structure, remains a subject of intense debate, and its exact nature continues to elude theoretical linguistics. A common view holds that only same-category constituents can be conjoined, which has been challenged by the many grammatical unlike coordinations found in natural language.
