Zipf's law is most easily observed byplottingthe data on alog-loggraph, with the axes beinglog(rank order) and log (frequency). For example, the word "the" (as described above) would appear atx= log(1),y= log(69971). It is also possible to plot reciprocal rank against frequency or...
With Zipf’s law being originally and most famously observed for word frequency, it is surprisingly limited in its applicability to human language, holding over no more than three to four orders of magnitude before hitting a clear break in scaling. Here, building on the simple observation that ...
齐夫定律(英语:Zipf's law,IPA英语发音:/ˈzɪf/)是由哈佛大学的语言学家乔治·金斯利·齐夫(George Kingsley Zipf)于1949年发表的实验定律。 它可以表述为: 在自然语言的语料库里,一个单词出现的频率与它在频率表里的排名成反比。 所以,频率最高的单词出现的频率大约是出现频率第二位的单词的2倍, ...
"Zipf's law states that given some corpus of natural language utterances, the frequency of any word is inversely proportional to its rank in the frequency table. " 举个例子,在Brown Corpus中,‘the’的排名是最高的,第一位,而它的出现次数是69971。排名第二位的词是‘of’,出现的次数为36411。
Random-text models have been proposed as an explanation for the power law relationship between word frequency and rank, the so-called Zipf's law. They are generally regarded as null hypotheses rather than models in the strict sense. In this context, recent theories of language emergence and evo...

Zipf’s Law Let f(w) be the frequency of a word w in free text. Suppose that all the words of a text are ranked according to their frequency, with the most frequent word first. Zipf’s Law states that the frequency of a word type is inversely proportional to its rank (i.e., f...
