8. The system of claim 7 , the graph generation component generates a Similarity Graph, prunes top E edges by edge weight for each node, and removes edges except edges that fall within at least one of the top E edges, where E is an integer from one to infinity.
7. The system of claim 6 , the graph generation component provides a noise filter for the Co-occurrence Graph that, at least in part, prunes edges that are less than a first given threshold and prunes nodes that have less than a second given threshold.
