ELSE

The ELSE rule is an alias for the COMBINE rule which is only used as an optional 3rd child of an if rule.

Parent

• IF
• note: it is an error for this rule to have any other parent than an if

Score calculation

Scores as a COMBINE rule

Evidence calculation

The evidence is the union of all its children’s evidence if it is selected by the if rule

Attribute information

• any attribute

Children restrictions

Any rule other than those restricted to a specific parent

Example

<if stem="1" >
    <condition>
        <text data="cat" />
    </condition>
    <then weight="80" >
        <text data="cat" />
    </then>
    <else weight="40" >
         <text data="dog" />
    </else>
</if>

This document mentions both cats and dogs

The else rule will be discarded - so even though it will score 0.4 and have evidence “dogs” this will not be passed up to the parent if rule

The parent if will have a score of “0.80” and 1 evidence phrase (“cats”)

Whilst on

This document only mentions dogs

The else rule will be used as the score and evidence for the if rule
