两篇新论文探讨了交换距离最小化原则作为影响人类语言词序的一个因素。研究表明，即使在没有主导SOV或SVO结构的语言中，主语、宾语和动词顺序的变化也可以用该原则来解释。其中一篇论文引入了一个数学框架来衡量词语顺序和手势顺序的最优性，发现跨语言的手势最优性至少为77%。 AI
影响 引入了一个分析语言结构的新数学框架，可能影响未来的NLP研究。
排序理由 arXiv上发表了两篇学术论文，介绍了一种新的语言学理论。

arXiv:2604.26726v1 Announce Type: new Abstract: Languages of the world vary concerning the order of subject, object and verb. The most frequent dominant orders are SOV and SVO, and researchers have tailored models to this fact. However, there are still languages whose dominant or…
Languages of the world vary concerning the order of subject, object and verb. The most frequent dominant orders are SOV and SVO, and researchers have tailored models to this fact. However, there are still languages whose dominant order does not conform to these expectations or ev…
arXiv:2604.01938v4 Announce Type: replace Abstract: The structure of all the permutations of a sequence can be represented as a permutohedron, a graph where vertices are permutations and two vertices are linked if a swap of adjacent elements in the permutation of one of the verti…
