McCOWAN et al.: The appropriate use of Zipf’s law in animal communication studies. ANIMAL BEHAVIOUR, 2005, 69, F1–F7 (PDF; 167 kB) Then Zipf's law states that r * Prob(r) = A, where A is a constant which should empirically be determined from the data. In most cases A = 0.1. Zipf's law is not an exact law, but a statistical law and therefore does not hold exactly but only on average (for most words). Taking into account that Prob(r) = freq(r) / N we can rewrite Zipf's law as 2019-05-06 · This law applies to words in human or computer languages, operating system calls, colors in images, etc., and is the basis of many (if not, all!) compression approaches.

According to Zipf's law, the frequency of a given word is dependent on the inverse of it's rank. Zipf's law is one of the many important laws that plays a significant part in natural language processing, the other being Heaps' Law. According to Zipf's law, in a list of word forms ordered by the frequency of occurrence, the frequency of the rth word form obeys a power function of r (the value r is called the rank of the word form).
