Introduction of ARCS
"Understanding Is Collocation"(Department of Cognitive Sciences , Berkeley)
In every language there are items that co-occur with high frequency, others that co-occur when need arises, and still others whose co-occurrence seems impossible.
With ARCS you can find the best collocation for your thought by looking at a screen that shows you all authentic and acceptable co-occurrences. In addition you can find examples for real usage. Synonyms and related words will enable you to replace the headword by an acceptably fitting word or phrase.
It is notable that collocation is used as a criterion both for topic and style.
The learner of English as a second or foreign language can hardly expect that collocations will have the same meaning cross-culturally. Secondly, there are items which are semantically compatible but are not associated habitually enough to be considered collocations by native speakers. "Even the extremely proficient foreign language speaker is still to be marked out as a non-native speaker if in his speech and writing he seems to avoid the collocations that would be characteristic of the native speaker." (D.A. Wilkins)
The headwords of ARCS are mainly adjectives, adverbs, verbs and combinations of parts of speech of more than one word. They co-occur at least once in a text corpus of three million words.
