KNOWLEDGE DISCOVERY DATABASE IN
THE FIELD OF LIBRARY SCIENCE
PRESENTED BY- MEGHA
GOYAL
The knowledge discovery database
• KDD is the automatic extraction of non-obvious,
hidden knowledge from large volumes of data.
• KDD in databases is the non-trivial process of
identifying valid, potentially useful and
ultimately understandable patterns in data
Why do we need KDD
• Data is the important tool to gain a competitive
edge by providing improved, cutomized services.
Knowledge discovery database
• KDD in databases is the non-trivial process of identifying valid,
potentially useful and ultimately understandable patterns in
data.
1. LIST OF STEPS OF KDD:-
2. Data Cleaning- in this step, the noise and inconsistent data is
removed
3. Data integration-in this step, multiple data sources are combined.
4. Data selection-in this step, data relevant to the analysis task are
retreived from the database.
5. Data transformation- in this step, data is transformed or
consolidated into forms appropriate for mining by performing
aggregation operations.
6. Data mining- intellingent methods are applied in order to extract
data patterms.
7. Pattern evaluation- data patterns are evaluated
8. Knowledge presentation- knoledge is represented.
KDD PROCESS-
List of steps
Knowledge discovery Process
GOALS
DATA SELECTION, ACQUISITION&INTEGRATION
DATA REDUCTION AND PROJECTION
MATCHING THE GOALS
EXPLORATORY DATA ANALYSIS
DATA MINING
INTREPRETATION AND TESTING
CONSOLIDATION AND USE
KDD System-in Library
• In libraries online databases use KDD system
• It can be used in searching, classification and
acquisition process of libraries.
• Developing an understanding of application
domain helps in relevant prior knowledge.
• Cleaning of processing of data
• Choosing data mining task of KDD process like
classification.
• Consolidating discovered knowledge
