Integration of multiple data sources using the SAMBA framework. In the SAMBA framework (Tanay et al, 2004), different gene characteristics are represented by properties (A). Quantitative characteristics, such as gene expression levels, are discretized first. The genes and the properties are represented by nodes in a bipartite graph (B), where edges connect genes with the properties they have. The SAMBA algorithm seeks modules consisting of a subset of genes and a subset of properties, such that these subsets are densely connected in the graph.
