Consequently, given two suffixes x and y, our method posits xy as a composite suffix if xy and x are similar in terms of the words to which they attach.
we consider xy and x to be similar if their similarity value as computed by the formula below is greater than 0.6: where |W ¢ | is the number of distinct words that combine with both xy and x, and |W| is the number of distinct words that combine with xy.
