COLLOCATIONS STUDY BASED ON THE TEXT CORPORA

The problem of extracting and studying collocations on the basis of linguistic corpora is considered. Such concepts of corpus linguistics as representativeness and the corpus volume, corpus manager (Concordance) and text corpora peculiarities are studied. The examples of definitions of collocations are given from the point of view of traditional and corpus linguistics. The definition of collocation as statistically stable combinations of lexical units is especially underlined. Different approaches to the definition of context as a base of studying collocation are examined. Such advantages of using text corpora in the linguistic studies as comprehensiveness and relevance of textual information are studied as well as the special statistic methods of processing information. This method is called MI (mutual information) and it compares dependent context-related frequencies with independent ones and allows single out all possible collocations. The examples of extracting collocation of the word time are set.
