Collocation and word association.

This paper studies the relationship between grammar and language use by comparing word association and collocation. Since word association reveals mental semantic knowledge, usage-based approaches expect word association to mirror the relation between words in use, namely collocation. The paragraph is a more apt unit for collocation than the sentence in mirroring word association. Among measures of collocation, (simple) log likelihood and t-score turn out to be more consistent with association, with log likelihood leading by a small margin over MI or MI3. Overall, word association and collocation are quite close, but not perfectly close because of differences in relevant resources and the characteristics of lexical/semantic relations.
