This document summarizes a presentation given by LoreMa Auvil of the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign on July 28, 2008 at the High-Performance Computing in the Humanities, Arts, and Social Science Workshop. The presentation discussed text mining and defined clustering as taking a set of documents and similarity measure among them and finding clusters where documents within a cluster are more similar to each other than documents in separate clusters, with the goal of finding the correct set of related documents.
