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). WebI f you select a high threshold, you increase the specificity of the test, but lose sensitivity. If you make the threshold low, you increase the test's sensitivity but lose specificity. Prism displays these results in two forms. The table labeled "ROC" curve is used to create the graph of 100%-Specificity% vs. Sensitivity%.
