In corpus linguistics, collocation defines a sequence of words or terms that co-occur more often than would be expected by chance. In phraseology, collocation is a sub-type of phraseme. An example of a phraseological collocation (from Michael Halliday[1])is the expression strong tea. While the same meaning could be conveyed by the roughly equivalent *powerful tea, this expression is considered incorrect by English speakers. Conversely, the corresponding expression for computer, powerful computers is preferred over *strong computers. Phraseological collocations should not be confused with idioms, where meaning is derived, whereas collocations are mostly compositional. There are about six main types of collocation: adjective+noun, noun+noun, verb+noun, adverb+adjective, verbs+prepositional phrase, and verb+adverb. Collocation extraction is a task that extracts collocations automatically from a corpus, using computational linguistics. |
