Re: DM: Datamining Definition.

Hi all :

Well, coming myself from a background of Statistics and Operations 
Research, I could agree.
However, it depends on how wide or narrow you understand "statistics".

A bit wider would be :

" So I choose to define data mining as the application of any formal method 
around
decision theory to huge, messy data sets to maximize profits."

Formal method would comprise Statistics, Operations Research,AI/ML-methods 
and maybe future concepts from Mathematics.

Since I very seldom have experienced that the results of decision theory go 
to decisions without human interaction of some kind of management guy, I 
could return to "decision support" and suggest :

" So I choose to define data mining as any type of decision support in all 
cases of huge, messy data sets to maximize profits."

Of course decision support methods would mainly come from  Statistics, 
Operations Research,AI/ML-methods and maybe future concepts from Mathematics.


But :  A sales argument needs no definition.
But :  A strong movement will find it's way on campus, attached to 
CS-dept., Stats-dept., OR-dept.  or between existing disciplines. If strong 
and persistent enough it will create an own existence.

So let's wait and see how strong and persistent  DM  will be when the sales 
people move on !!
