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). 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 fr...

Zipf's law is a statistical phenomenon observed in many natural languages, where the frequency of a word is inversely proportional to its rank in its frequency distribution. In other words, the most frequently occurring word appears approximately twice as often as the second most frequent word, ...
forα ≈ 1 (Zipf,1936,1949).Footnote1In this equation,ris called thefrequency rankof a word, andf(r) is its frequency in a natural corpus. Since the actual observed frequency will depend on the size of the corpus examined, this law states frequencies proportionally: The most frequent ...
"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。

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 ...
Zipf's law是一个经验观察,它指出一个词或术语的频率与它的排名成反比。 关于Zipf's law的定量信息分析的途径: 界定研究目标:是对研究特定语料库中的词频感兴趣,还是探索Zipf定律在不同领域的适用性? 2. 收集数据:识别并获得一个合适的数据集进行分析。这可以是一个文本语料库、一个词频数据库,或来自另一个...

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...
