a modified frequency of a word form which prevents words with high frequency only in one part of a corpus (e.g. in one document) from high ranking in frequency lists (e.g. two words with the same frequency in the corpus, but first one is only in three documents in contrast to second one appearing in the whole corpus). For more details, see the ARF definition.
Adam Kilgarriff Prize
Adam Kilgariff (1960-2015) was a British corpus linguist and founder of Lexical Computing, the company behind Sketch Engine. Adam devoted his whole life to research at the intersection of corpus linguistic, computational linguistics and lexicography.
To honour our brilliant and much-loved colleague, we established the Adam Kilgarriff Prize for outstanding work in the fields to which Adam contributed so much: corpus linguistics, computational linguistics, and lexicography.
