2019-07-03 · Also known as Zipf's Law, Zipf's Principle of Least Effort, and the path of least resistance. The principle of least effort (PLE) was proposed in 1949 by Harvard linguist George Kingsley Zipf in Human Behavior and the Principle of Least Effort (see below).

Zipf’s Law In 1930-s, an American linguist George Kingsley Zipf was working on the distribution of words in natural languages when he noticed a curious phenomenon. Just over a hundred English words account for almost half of both spoken and written language.

Zipf's law states that in a corpus of a language, the frequency of a word is inversely proportional to its rank in the global list of words after sorting by decreasing frequency.

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 a statistical distribution in certain data sets, such as words in a linguistic corpus, in which the frequencies of certain words are inversely proportional to their ranks.

Zipf’s law is one of the empirical statistical regularities found within many natural systems, ranging from protein sequences of immune receptors in cells to the intensity of solar flares from the sun. Zipf’s Law is a statistical distribution in certain data sets, such as words in a linguistic corpus, in which the frequencies of certain words are inversely proportional to their ranks. Zipf’s Law describes one aspect of the statistical distribution in words in language: if you rank words by their frequency in a sufficiently large collection of texts and then plot the frequency against the rank, you get a logarithmic curve (or, if you graph on a log scale, you get a straight line).

Zipfs lag (uttalas zɪfs) är en empiriskt visad statistisk lag som säger att inom många tillämpningsområden inom såväl samhällsvetenskap som naturvetenskap gäller att vid stora mängder diskreta data är rankingfrekvensen (förekomsten av det vanligaste värdet, näst vanligaste värdet, osv) approximativt Zipffördelade.

Zipf's law. Zipf's law is an empirical law, formulated using mathematical statistics, named after the linguist George Kingsley Zipf, who first proposed it. Zipf's law states that given a large sample of words used, the frequency of any word is inversely proportional to its rank in the frequency table.

The last point in Zipf’s plot was eliminated since it is severely aected by the plateaux associated with the least, frequent words. "Zipfs lag är användbar som en grov beskrivning av frekvensfördelningen av ord på mänskliga språk: det finns några mycket vanliga ord, ett medelstort antal medelfrekventa ord och många lågfrekventa ord.
