Application ID: 15091967

Base Claim:
1. A computer-implemented method of generating an issue network from a document corpus, the method comprising: searching, using a computer, the document corpus for a set of documents discussing a starting issue, wherein the starting issue is one of a plurality of normalized issues defined by the document corpus; determining a set of normalized issues discussed by the set of documents discussing the starting issue, wherein the set of normalized issues also includes the starting issue; determining instances of co-occurrences of individual normalized issues of the set of normalized issues within individual cases of the set of documents; linking individual normalized issues of the set of normalized issues based on their co-occurrences within the set of documents, wherein the linked individual normalized issues at least in part define the issue network; and storing the linked individual normalized issues in a non-transitory computer-readable medium.

Claim 8:
8. The computer-implemented method of claim 1 , further comprising creating at least one issues-by-case metadata file, wherein the searching of the document corpus for the set of documents discussing the starting issue, the determining of the set of normalized issues discussed by the set of documents discussing the starting issue, and the determining of the instances of co-occurrences of individual normalized issues of the set of normalized issues within individual cases of the set of documents comprises searching the at least one issues-by-case metadata file.
