CRISP-DM is the leading data mining methodology, according to 2007 KDnuggets Poll on Data Mining Methodology.

CRISP-DM was selected by 42% of respondents, which amazingly is the exactly the same percentage (42) as in 2004 KDnuggets Poll on Data Mining Methodology.

Among significant changes, percent who use their own methodology declined from 28% in 2004 to 19% in 2007, and percent who use SEMMA increased from 10 to 13.

Here are the full results of 2007 KDnuggets Poll on Data Mining Methodology.

Note: 42 is the Answer to Life, the Universe, and Everything, according to Douglas Adams, but the ultimate question is still in dispute. Amazingly, 42 is the answer to:

"What percentage of KDnuggets Readers use CRISP-DM as main data mining methodology?"

both in 2004 and 2007 Polls

Could this be just a coincidence or perhaps data mining methodology plays a role in the ultimate Answer to Life, the Universe, and Everything ?
