Figure 2.

Illustration of context-based dissimilarity and hierarchical context-based dissimilarity. The two proteins xi and xj, on which the dissimilarity is to be measured, are in the first row. The nearest neighbors of these two proteins are listed below them as the context, respectively. (a) The traditional context <a onClick="popup('http://www.biomedcentral.com/1471-2105/13/S7/S2/mathml/M65','MathML',630,470);return false;" target="_blank" href="http://www.biomedcentral.com/1471-2105/13/S7/S2/mathml/M65">View MathML</a>; (b) The proposed hierarchical context <a onClick="popup('http://www.biomedcentral.com/1471-2105/13/S7/S2/mathml/M66','MathML',630,470);return false;" target="_blank" href="http://www.biomedcentral.com/1471-2105/13/S7/S2/mathml/M66">View MathML</a>, p = {1, 2, 3}.
