Key concepts
What is data mining?
Data mining technique was first introduced and used in the
late 1980s. Significant developments were made in the 1990s
and continued through the 21st century (Hand, Mannila&
Smyth, 2001). Data mining is the process of discovering the
pattern of internal relation and structure of data (Berry &
Linoff, 2004). In fact, data mining discovers the interesting,
unexpected and valuable constructions from inside of large
data and is an activity corresponding to statistics and analysis
of data (Hand et al., 2001).
