WebJan 2, 2024 · Collocations are expressions of multiple words which commonly co-occur. For example, the top ten bigram collocations in Genesis are listed below, as measured using Pointwise Mutual Information. While these words are highly collocated, the expressions are also very infrequent. Therefore it is useful to apply filters, such as ignoring all bigrams ... WebTrigrams are overlapping 3-char strings from a text, extracted by a couple of rules, and a trigram matching method may improve the probability of identifying synonym phrases or …
