The Ising Model for Changes in Word Ordering Rule in Natural Language

Abstract

The order of `noun and adposition' is the important parameter of word ordering rules in the world's languages. The seven parameters, `adverb and verb' and others, have a strong dependence on the `noun and adposition'. Japanese as well as Korean, Tamil and several other languages seem to have a stable structure of word ordering rules, as well as Thai and other languages which have the opposite word ordering rules to Japanese. It seems that each language in the world fluctuates between these two structures like the Ising model for finite lattice.
