Selection
DATA CLEANING
• Remove Noise and Inconsistent Data
DATA INTEGRATION
• Where multiple data sources may be combined
DATA SELECTION
• Where data relevant to the analysis task are
retrieved from the data base
DATA TRANSFORMATION
• Where data are transformed and consolidated
into forms appropriate for mining by
performing summary or aggregation operation
Data Mining
• An essential Process where intelligent
methods are applied to extract data patterns
PATTERN EVALUATION
• To identify the truly interesting patterns
representing knowledge based on
interestingness measures
KNOWLEDGE REPRESENTATION
• Where visualization and knowledge
representation techniques are used to present
mined knowledge to users
