a statistic measure for identifying collocations. It expresses the typicality of the co-occurence of the node and the collocate. It is used in the word sketch feature and also when computing collocations from a concordance.
It is only based on the frequency of the node and the collocate and the frequency of the whole collocation. logDice is not affected by the size of the corpus and, therefore, can be used to compare the scores between different corpora. logDice is the preferred option when working with large corpora.
