Thus, tuning k-mer length to the expected frequency of mismatches may result in application-adapted search sensitivity.

WebbThus, we see two more positive examples and we see our ﬁrst negative example. If X = B, there are again three neighbors, but only one pair of neighbors, A and C, has an edge. Thus, we have two more negative examples, and one positive example, for a total of seven positive and three negative. Finally, when X = D, there are four neighbors.

One obvious example is the "find-similar-document" query, on traditional text corpora or the World-Wide Web. More generally, a similarity measure can be used to cluster objects, such as for collaborative filtering in a recommender system, in which “similar” users and items are grouped based on the users’ preferences.
