Hide Attributes In an Explanation

To hide attributes in an explanation, you use the silent and invisible parameters.

• The silent parameter is used to hide all attributes in the explanation below the attribute on which the parameter is used.
• The invisible parameter is used to hide the attribute on which the parameter is used in the explanation.

You can also use both parameters together to cut off an explanation above a particular attribute.

Show me an example

Consider these Word rules:

the customer is eligible for a loan if

the customer meets the minimum eligibility requirements and

the customer meets the loan serviceability tests and

the customer is able to offer sufficient security for the loan

the customer meets the loan serviceability tests if

the customer passes the employment tests and

the customer passes the credit history tests and

the customer’s earnings are sufficient to repay the loan

the customer passes the credit history tests if

the customer has not defaulted on a credit card and

the customer has not defaulted on a bank loan and

the customer has not been declared bankrupt

Without any silent or invisible parameters, the explanation when the customer has defaulted on a credit card would look like this:

With a silent parameter on the attribute 'the customer passes the credit history tests', the explanation when the customer has defaulted on a credit card would look like this:

With an invisible parameter on the attribute 'the customer passes the credit history tests', the explanation when the customer has defaulted on a credit card would look like this:

With both a silent and invisible parameter on the attribute 'the customer passes the credit history tests', the explanation when the customer has defaulted on a credit card would look like this:

Hide all attributes in an explanation below a particular attribute

To apply the silent parameter to an attribute, in Policy Modeling:

1. On the Data tab, double-click on the attribute in the attribute list.
2. In the Edit Attribute dialog, click the Explanation options button.
3. In the Explanation Options dialog, select the appropriate check boxes in the Silent section.
   • For Boolean attributes, you can mark the attribute as always silent, or silent only if the attribute is true, false or uncertain.
   • For non-Boolean attributes, you can mark the attribute as always silent, or silent only if it is certain or uncertain.

Hide a particular attribute in an explanation

To apply the invisible parameter to an attribute, in Policy Modeling:

1. On the Data tab, double-click on the attribute in the attribute list.
2. In the Edit Attribute dialog, click the Explanation options button.
3. In the Explanation Options dialog, select the appropriate check boxes in the Invisible section.
   • For Boolean attributes, you can mark the attribute as always invisible, or invisible only if the attribute is true, false or uncertain.
   • For non-Boolean attributes, you can mark the attribute as always invisible, or invisible only if the attribute is certain or uncertain.

Cut off an explanation above a particular attribute

Silent and invisible parameters can be used together so that both an intermediate attribute and any rules that prove that attribute are not included in the explanation. It may help to think of this as "chopping off" the explanation immediately above the attribute to which the pair of parameters is attached.
