The Zipfian Challenge: Learning the statistical fingerprint of natural languages

Christian Bentz


Abstract
Human languages are often claimed to fundamentally differ from other communication systems. But what is it exactly that unites them as a separate category? This article proposes to approach this problem – here termed the Zipfian Challenge – as a standard classification task. A corpus with textual material from diverse writing systems and languages, as well as other symbolic and non-symbolic systems, is provided. These are subsequently used to train and test binary classification algorithms, assigning labels “writing” and “non-writing” to character strings of the test sets. The performance is generally high, reaching 98% accuracy for the best algorithms. Human languages emerge to have a statistical fingerprint: large unit inventories, high entropy, and few repetitions of adjacent units. This fingerprint can be used to tease them apart from other symbolic and non-symbolic systems.
