Are There Data Mining Tool Comparisons?

I maintain a comprehensive list of data mining tools / software at www.kdnuggets.com/software/.

I have been running annual polls on Data Mining Software Usage, which, while not perfect, offer some measure of tool popularity. Here are some recent KDnuggets polls on Data Mining Tools:

• Data Mining Tools Used, May 10 - 24, 2009.
• What data mining tools have you used for a real project in the past 6 months?, May 2008.
• Data Mining (Analytic) tools you used in 2007, May 2007.
• Data mining/analytic tools you used in 2006.

• Magic Quadrant for Customer Data Mining, July 2008
• Magic Quadrant for Customer Data Mining, 1Q06.
