Figure 2

Illustration of context-based dissimilarity and hierarchical context-based dissimilarity. The two proteins x _i and x _j , 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 $\mathcal{N}\left(i\right)$; (b) The proposed hierarchical context ${\mathcal{N}}_p\left(i\right)$, p = {1, 2, 3}.
