Features that are independent of any particular sense of the keyword, on the other hand, have no such restriction, and are just as likely to appear in the context of one sense as any other.
a low count for the co-occurrence of two potential features over a large corpus of documents for keyword k is a reliable indicator that the two features are part of the glosses of two distinct senses of k. GLOSSY's collocation detector begins by indexing the corpus and counting the frequency of each vocabulary word.
