• a means for selecting one or more sources that are associated with a signature and forming the selected sources into a community for each of the one or more signatures;
• and
• a means for constructing a graph representation of a plurality of communities, the graph representation including at least a plurality of vertices representing the plurality of communities respectively and one or more edges connecting the plurality of vertices, the one or more edges representing one or more input attributes, output attributes, or keywords or combination thereof that are shared between the communities represented in the connecting vertices.
