Keyword (linguistics)

From Wikipedia, the free encyclopedia

In corpus linguistics a keyword is a word which occurs in a text more often than we would expect to occur by chance alone. Keywords are calculated by carrying out a statistical test (e.g., loglinear) which compares the word frequencies in a text against their expected frequencies derived in a much larger corpus, which acts as a reference for general language use. AntConc is a freely available text analysis tool capable of calculating keywords.
