Edge Weighted


Definition

Edge weight EW(u,v) use the following commonly used measures for evaluating the relationship between two proteins, whose nodes are connected by an edge in a PPI network and defined as:

EW(u,v) = NTE(u,v) * PCC(u,v) * GE(u,v)

where GE is GO functional similarity, PCC is co-expression levels among genes and NTE is the number of times that a PPI pair involved in PPI triangles.
