标题: 关于Data Mining
[i:53f56]乐观的说法……Berry and Linoff (1997)[/i:53f56]

分析报告给你后见之明(hindsight)
统计分析给你先机(foresight)
Data Mining给你识见(insight)

这三者都是在既有的资料上做分析,在概念上应该并无轩轾,差别只是手上的资料大小与性质。所以,方法不同才有定义的不同。


[i:53f56]负面的定义……Friedman, J. (1997)[/i:53f56]

Data mining is a commercial enterprise that seeks to mine the miners.


[i:53f56]中肯的说法……Hand, D. J., Blunt, G., Kelly, M. G. and Adams, N. M. [/i:53f56]

Data mining is the process of seeking interesting or valuable information in large data bases.
