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).
