A blog about the implications of the statistical properties of language Zipf’s law is a very powerful tool for those who want to know how to learn vocabulary fast. It frees up your hands and allows you to learn language the natural way. Obviously, you still can complete a deck of flashcards with 5000 most frequent French words, if you feel like doing so. Zipf's Law In the English language, the probability of encountering the th most common word is given roughly by for up to 1000 or so. The law breaks down for less frequent words, since the harmonic series diverges.

Zipfs law

388) should have included the following sentence at the end. If you remember, Zipf’s Law says that the probability P of encountering a word with ranking r is given by P(r) = 0.1/r. Guessing that there’s a similar distribution for punctuation marks, I played around with a variety of different values for the numerator of the fraction, eventually settling on 0.3 as a reasonable proposition. 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).

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. Named for George Kingsley Zipf.
