Protein overlapping patterns of output sets of modules. The average overlapping rate of proteins with respect to the number of modules in each output set. The flow-based algorithm using semantic similarity and semantic interactivity generated ten different output sets of modules by varying parameter values. Each output set has different number of modules in the range between 50 and 250. The average overlapping rate represents the average number of occurrence of proteins in the modules. The identified modules have a similar overlapping pattern to the MIPS functional categories.
