Graph-partitioning
WebGraph partitioning is a theoretical subject with applications in many areas, principally: numerical analysis, programs mapping onto parallel architectures, image segmentation, VLSI design. During the last 40 years, the literature has strongly increased and big improvements have been made. This book brings together the knowledge accumulated … WebAfter modeling two ontologies as a bipartite graph, we apply bipartite graph co-clustering technique to establish mappings between two ontologies. Co-clustering in a bipartite graph can be naturally formulated as a graph-partitioning problem, which aims at getting the vertex partition with minimum cut (Dhillon 2001; and Zha et al. 2001).
