Interestingly, Zipf’s Law also applies to urban population sizes in nearly every developed country across the world and it works well when used for metropolitan areas, which are areas defined by the natural distribution and connectivity of populations rather than arbitrary political boundaries (e.g. counting Oakland and San Francisco as one metro area as opposed to two different cities).

In linguistics, brevity law (also called Zipf's law of abbreviation) is a linguistic law that qualitatively states that the more frequently a word is used, the shorter that word tends to be, and vice versa; the less frequently a word is used, the longer it tends to be.

By Zipf’s Law, there will only be around 0.1 * 0.07 * 196,095 = 1,372 training examples for the 10th most common word. The number of examples will continue to rapidly decrease by a factor of 10 Zipf’s Law. The observation of Zipf on the distribution of words in natural languages is called Zipf’s law. It desribes the word behaviour in an entire corpus and can be regarded as a roughly accurate characterization of certain empirical facts. Zipf’s law: when we draw log-rank against log-size, we get a straight line, with a slope, which we shall call z, that is very close3 to 1. In terms of the distribution, this means that the probability that the size of a city is greater than some S is proportional to 1/S: P(Size . S) 5a/Sz, with z . 1.

Zipf’s law is actually a really weird quirk of language that has helped shed light on some other really strange aspects of human society. It’s one of those coincidences-aren’t-coincidences-but-also-are-coincidences type deal. So, what is Zipf’s law, anyway? How does it work?

2016-11-13 · Zipf’s Law for Cities – A Simple Explanation for Urban Populations . A quick glance at the list of the most populous cities in the United States reveals a very interesting, though apparently random trend. Zipf's law also applies to celestial bodies in the solar system, because the process is very similar to the way companies are created and evolve, involving mergers and acquisitions.

If you rank the words by their frequency in a text corpus, rank times the frequency will be approximately constant. This is known as Zipf's law.

There is nothing surprising about this, we know that we use some of the words very frequently, such as “the”, “of”, etc, and we rarely use the words like “aardvark” (aardvark is an animal species native to Africa).

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
