Rule Editor Help

In ZEUS, a rulebase refers to a collection of precondition-action rules. This editor can be used to add individual rules to a rulebase, and editing existing rules, the latter activity typically involving the following steps:

Enter a new rules
Enter the rule's trigger conditions
Enter the rule's action consequences

Entering a New Rule

To add a new rule click the

button - this inserts a new entry into the table, which can be renamed to reflect the function of this rule. If the rule is the selected entry in the rule table its conditions and actions can then be edited.

Entering a Rule Condition

Rules are triggered in response to the detection of particular facts or variables. A rule can have one or more conditions, which are entered as separate lines into the Conditions panel of the Rulebase editor. The easiest way to enter a fact is to choose its name from the fact tree shown in the Ontology panel on the bottom right-hand corner, then click on the Insert Fact or Insert with ID buttons.

Entering a Rule Action

A rule's actions occur when the all the rule's conditions are satisfied, the applicable actions can be chosen from the list on the right-hand side of the editor and inserted by pressing the Insert Action button. The syntax and effects of the actions are explained in the ZEUS Realisation Guide.
