Results of 2007 Data Miner Survey

Results of 2nd Annual Rexer Analytics Data Miner Survey is out. There are few interesting findings in the survey, which include SPSS and not SAS still being the most widely used Data Mining tool.

Let me share the highlights at the survey here.
  • 27-item survey of data miners, conducted on-line in early 2007
  • 314 responses from individuals in 35 countries
  • Regression, decision trees and cluster analysis were the most commonly used algorithms (mean number of algorithms used: 6.8)
  • Top challenges data miners report are dirty data, data access, and explaining data mining to others
  • SPSS, SPSS Clementine, and SAS are the three most frequently utilized tools (mean number of tools used: 4.5)
  • There is increasing interest in the Oracle Data Mining tool, and decreasing interest in C4.5/C5.0/See5
  • The primary factors data miners consider when selecting an analytic tool are: 1) the dependability and stability of software, 2) the ability to handle large data sets, and 3) data manipulation capabilities
  • The findings vary somewhat depending on the domain in which the data miner works, the tools used, geography, and several other dimensions
For details, please contact folks from Rexer.

I am going for a 2 week trip to Nepal, my home country, starting today and am pretty much excited. Going after almost 2 years, so hoping to have great time with my family and friends. For that time I may be out of touch from this blog, after all family deserves equal attention and time, if not more. What say!!

Cheers !!
