Similarly, preferential attachment intuitively, “the rich get richer” or “success breeds success” that results lsy the Yule—Simon distribution has been shown to fit word frequency versus rank in language [16] and population versus city rank [17] better than Zipf’s law. In every case Belevitch obtained the remarkable result that a first-order truncation of the series resulted in Zipf’s law.

This can markedly improve the fit over a simple power-law relationship. Discrete distributions Computational linguistics Power laws Statistical laws Empirical laws Tails of probability distributions Quantitative linguistics Bibliometrics Corpus linguistics introductions.

Human Behavior and the Principle of Least Effort. He then expanded each expression into a Taylor series.

Zipf’s Law — from Wolfram MathWorld

Retrieved 8 July SIAM Review, 51 4— From Wikipedia, the free encyclopedia. The Lej distribution is sometimes called the discrete Pareto distribution [18] because it is analogous to the continuous Pareto distribution in the same way that the discrete uniform distribution is analogous to the continuous uniform distribution. See Terms of Use for details.


The appearance of the distribution in rankings of cities by population was first noticed by Felix Auerbach in Degenerate Dirac delta function Singular Cantor. This page was last edited on 30 Ziptat This page was last changed on 19 Octoberat Vespignani Explaining the uneven distribution of numbers in nature: The psychology of language. It has been argued that Benford’s law is a special bounded case of Zipf’s law, [19] with the connection between these two laws being explained by their both originating from scale invariant functional relations from statistical physics zi;f critical phenomena.

Lfy appearance of the distribution in rankings of cities by population was first noticed by Felix Auerbach in In other projects Wikimedia Commons. Archived PDF from the original on The connecting lines do not indicate continuity.

In human languages, word frequencies have a very heavy-tailed distribution, and can therefore be modeled reasonably well by a Zipf distribution with an s close to 1. Zopf Li has shown that in a document in which each character has been chosen randomly from a uniform distribution of all letters plus a space characterthe “words” follow the general trend of Zipf’s law appearing approximately linear on log-log plot.

Zipf’s Law

Retrieved from ” https: The “constant” is the reciprocal of the Hurwitz zeta lsy evaluated at s. The same relationship occurs in many other rankings unrelated to language, such as the population ranks of cities in various countries, corporation sizes, income rankings, ranks of number of people watching the same TV channel, [5] and so on.


Zipf’s law is most easily observed by plotting the data on a log-log graph, with the axes being log rank order and log frequency. In other projects Wikimedia Commons.

He took a large class of zupf statistical distributions not only the normal distribution and expressed them in terms of rank. From Wikipedia, the free encyclopedia. It is also possible to plot reciprocal rank against frequency or reciprocal frequency or interword interval against rank. Indeed, Zipf’s law is sometimes synonymous with “zeta distribution,” since probability distributions are sometimes called “laws”. Power-Law Distributions in Empirical Data.

Thus the most frequent word will occur about twice as often as the second most frequent word, three times as often as the third most frequent word, etc.
