10. What data mining is?

11. What „google” says?

12. What „google” says?
Data mining (the analysis step of the "Knowledge Discovery in
Databases" process, or KDD), an interdisciplinary subfield of computer
science,

13. What „google” says?
Data mining (the analysis step of the "Knowledge Discovery in
Databases" process, or KDD), an interdisciplinary subfield of computer
science, is the computational process of discovering patterns in large
data sets involving methods at the intersection of artificial intelligence,
machine learning, statistics.

18. What „google” says?
The overall goal of the data mining process is to extract information
from a data set and transform it into an understandable structure for
further use.

further use.

21. What „google” says?
Aside from the raw analysis step, it involves database and data
management aspects, data pre-processing, model and inference
considerations, interestingness metrics, complexity considerations,
post-processing of discovered structures, visualization, and online
updating.
