“…So far, density-based clustering ( Adamcsek et al, 2006 ;Altaf-Ul-Amin et al, 2006 ;Bader and Hogue, 2003 ), hierarchical clustering ( Ahn et al, 2010 ;Arnau et al, 2005 ), partition-based clustering ( BJ and D., 2007 ;King et al, 2004 ), flow simulation-based clustering ( Enright et al, 2002 ;Pereira-Leal et al, 2004 ;Cho et al, 2007 ) and other methods ( Hwang et al, 2008 ;Inoue et al, 2010 ;Lecca and Re , 2015 ;Nepusz et al, 2012 ;Wu et al, 2009 ;Yu et al, 2015a ;Liu et al, 2017 ;Maddi and Eslahchi, 2017 ) have been proposed to detect protein clusters based on the PPI data. In addition, the source of necessary biological information has been used to locate protein complexes in PPI networks ( Andreopoulos et al, 2009 ;Lakizadeh et al, 2015 ) effectively. There is a common problem among these methods, in that way the node is just one dimensional vertex in the network without considering other biological information hidden in the node (protein).…”
