ideographic. The use of letter frequencies and frequency analysis plays a fundamental role in cryptograms and several word puzzle games, including hangman...

concept when introducing his Keyword-in-Context automatic indexing process. The phrase "stop word", which is not in Luhn's 1959 presentation, and the associated...

TFIDF, TF–IDF, or Tf–idf), short for term frequency–inverse document frequency, is a measure of importance of a word to a document in a collection or corpus...

interval. The label K comes from the German word Kennziffer meaning "characteristic digit". The K-index was introduced by Julius Bartels in 1939. The...

inverted index: This index can only determine whether a word exists within a particular document, since it stores no information regarding the frequency and...

and frequency-based sorting are employed in other languages as well, though often at word level, not at character or letter level. A Chinese word consist...

to the frequency table of words in a text or corpus of natural language: word frequency ∝ 1 word rank . {\displaystyle {\text{word frequency}}\propto...

methods of document classification where, for example, the (frequency of) occurrence of each word is used as a feature for training a classifier. It has also...

by most people. The frequency with which words are in normal use affects the readability of text. Until the 1980s, the fog index was calculated differently...

automated techniques where word frequencies are calculated and those with a frequency over a pre-determined threshold are used as index terms. A stop-list containing...

In statistics, the frequency or absolute frequency of an event i {\displaystyle i} is the number n i {\displaystyle n_{i}} of times the observation has...

such as latent semantic indexing have been proposed as a means of automatically identifying linguistic information based on word context. A bilingual concordance...

output a frequency control value at each clock sample. A phase-to-amplitude converter (PAC), which uses the phase accumulator output word (phase word) usually...

incremental (memory-efficient) algorithms for term frequency-inverse document frequency, Latent Semantic Indexing, Random Projections and Latent Dirichlet Allocation...

the moment at which the word is spoken; and here indexically refers to a locational frame including the place where the word is spoken. Linguistic expressions...

In marketing and advertising, frequency refers to the number of times a target audience is exposed to a particular message or advertisement within a given...

has high frequency components and selecting only the high frequency coefficients filters the text from the non-text regions in an image. In word recognition...

code frequency deviation is 1/1,540 times the carrier frequency deviation for L1 because the code frequency is 1/1,540 of the carrier frequency (see §...

reflection. Like negative-index materials, SNGs are innately dispersive, so their εr, μr and refraction index n, are a function of frequency. Hyperbolic metamaterials...
