Using Decision Rules (IF-THEN Rules)
If-then Rules, also called Decision Rules or Production Rules are a basic structure in data mining and expert systems. This method of knowledge representation is simple and easy to use for data analysis. Each rule defines a piece of overall knowledge. Rules can be edited, removed or added independently from each other.
The Rule cosists of condition and conclusion. In case if there are many conditions, they are separated by "and".
For example: IF condition1 and condition2 THEN conclusion
As a conclusion, ESTARD Data Miner represents so-called Classes - values, obtained from database or created manually by the user. During the rules creation, the progtam reveals all rules for classes, groups them and outputs.
For convenient viewing the, the conclusion (Class) is placed before the Rule.
