Claim:
1. A method of pivoting from a graph of semantic similarity of documents to a derivative graph, the method comprising: obtaining a first graph comprising more than 1000 nodes and more than 2000 edges, each of the first-graph edges linking two of the first-graph nodes and denoting semantic similarity of unstructured text in documents corresponding to the two linked first-graph nodes, and the first graph being generated from natural language processing of a corpus of unstructured text documents; detecting, by one or more processors, more than 100 entities mentioned in the unstructured text documents; and generating, by one or more processors, a derivative graph comprising more than 100 nodes respectively corresponding to the detected entities mentioned in the unstructured text documents, wherein generating the derivative graph comprises, for each pair of the derivative-graph nodes:
