Besides the two well-known Open Source tools RapidMiner and Weka, are there any other good tools (either Open Source or Commercial), which you can recommend for data mining?
Thanks in advance!
My money is on R, see e.g. the Machine Learning task view.
How about the open source Orange data mining toolkit.
You can look at my project - Data Mining SDK.
According to the KDnuggets Poll 2011, RapidMiner once more is the most widely used data mining solution world-wide: http://www.kdnuggets.com/2011/05/tools-used-analytics-data-mining.html
If it is commercial software the following two are awesome
- SAS
- SPSS
Another very powerful opensource tool is Knime. In some respects it is better than RapidMiner. As for commercial here's what I've tried:
1.Polyanalyst 2.SPSS Clementine 3.Kxen 4.Statistica Data Miner 5.MATLAB
I like Polyanalyst the best. But it's just my opinion.
According to the yearly KDnuggets Polls 2007, 2008, and 2009, RapidMiner is the most widely used Open Source Data Mining Solution among data mining experts world-wide: KDnuggets Data Mining Tool Poll 2009
RapidMiner is open source and 100% Java, RapidMiner is much more flexible and offers significantly more functionality than Weka and KNIME.

The data mining tool I used(also machine learing tools):
Weka: classfication, clustering, association rule, decision tree......
Cluto: clustering
libsvm: classification
And from many posts, I find there still other famous tools which I haven't used:
Orange
R
RapidMiner
SAS
SPSS
There must be other useful tools that I'm not aware of.
