The horizontal axis is the index k . 6 Mar 2017 In short, this law states that in natural languages, the frequency of a given words usage is inversely proportional to it's rank.

It says that the frequency of occurrence of an instance of a class is roughly inversely proportional to the rank of that class in the frequency list. "The weak version of Zipf's Law says that words are not evenly distributed across texts; instead, there are a few words that are very common and a very large number of words that are very rare. And Zipf’s law: The largest value of should obey an approximate power law, i.e. it should be approximately for the first few and some parameters. In many cases, is close to.

Zipfs law

This is the statement of Zipf’s law.4 3.

Let N be the number of elements, k be their rank, s be the value of the exponent characterizing the distribution. Zipf’s law predicts that out of a population of N elements, the frequency of elements of rank k, f(k;s;N), is: f(k;s;N) = 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 r * freq(r) = A * N To establish that Zip's law holds we need to compute freq(r), which involves computing the This phenomenon is commonly referred to as Zipf’s Law, after linguist George Zipf, who, in 1949, observed a similar pattern for word-usage frequency in several different languages.
