Case Definition
Index Definition
Modification/Preprocess Definition
Global Adapting Rule Definition
See examples

2. Case Definition
Build case model, all the cases can be instantiated from this model
Build domain ontologies
Define features which can represent domain knowledge
Keywords: case definition is , type is , field
Keywords: weight is (important features)
See examples

3. Index Definition To identify/specify index features
To facilitate building discrimination feature network
To facilitate index searching algorithm
Keyword: index definition is , index on
See examples

4. Modification/Preprocessing Definition
Preprocessing: rules used to alter “use abnormal case”
Modification:
Specify similar symbols or numbers
Specify symbols as abstractions of others
Keywords: modification definition is , abstraction is , similar range …to … , field
Keywords: preprocess rule definition is
See examples

5. Global Adapting Rule Definition
Build adapting rules to modify solution retrieved from case-base to fit current problem
Rules are derived from domain knowledge, formula and constraints among design parameters
Keywords: repair rule definition is , repair rule , when , then , repair
See examples

6. Case Instance Definition
Represent design experiences which form Case-Base
Define local rules to adjust between problem definition and solution
Keywords: case instance , solution is , local field definition , local repair rule definition , repair rule
See examples

7. Global Adapt Rule Definition
Delete sample document icons and replace with working document icons as follows:
From Insert Menu, select Object...
Click “Create from File”
Locate File name in “File” box
Make sure “Display as Icon” is checked
Click OK
Select icon
From Slide Show Menu, Select “Action Settings”
Click “Object Action” and select “Edit”
