Rapid Prototyping with Mathematica

January 6th, 2011

In a previous post we mentioned that Tim Hitchcock and Bill Turkel are using Mathematica to create prototypes of various text mining and visualization tools.  One advantage of using Mathematica is that it is very easy to build dynamic prototypes that can be shared with colleagues to get their feedback.  We have put one of these online at the Wolfram Demonstrations Project: “Term Weighting with TF-IDF.”  The TF-IDF is a common information retrieval measure that indicates which terms in a document (in this case a legal trial) should be weighted most heavily when trying to understand what the document is about.
