Clusters of documents can be summarized by finding the top terms (words) for the documents in the cluster, e.g., by taking the most frequent k terms, where k is a constant, say 10, or by taking all terms that occur more fre- quently than a specified threshold. Suppose that K-means is used to find clusters of both documents and words for a document data set.
(a) How might a set of term clusters defined by the top terms in a document cluster differ from the word clusters found by clustering the terms with K-means? (b) How could term clustering be used to define clusters of documents?
