PTLR Convergence Results

This page details the papers found in the automated convergence analysis of candidate core paper for the Patent Thicket Literature Review (PTLR). References from the input papers were matched against one another using a combination of n-gram and longest common subsequence fuzzy matching. The counts are approximate where indicated, as in these instances A <-> B and B<->C but due to the fuzzy matching constraints A did not match to C. Thus the raw results list provide a count for A of 1 and a count for B of 1, and a user then removed the (duplicate) B reference and incremented the A count by 1. This incrementation may be incorrect (biased down) when A and B both matched to incomplete subsets.
