Semaphore Classification Server Rulebase Reference

Gives a class value to a category rule. If a category rule scores above threshold then the class value is used to provide the value of the META added to the output.

NB due to historic usage a category has a class and name which are returned as a META name and value - whilst this is slightly confusing it would be even more confusing if the behaviour was altered due to the obvious confusion caused by what a name attribute actually means on a category rule.

Applies to

Values

  • “CLASS VALUE”

Example

<category class="VEHICLES" name="car">
    <any>
        <text data="car"/>
        <text data="automobile"/>
    </any>
</category>
<any category="1" class="VEHICLES" name="truck" >
    <text data="truck"/>
    <text data="4x4"/>
    <text data="semi"/>
    <text data="pickup"/>
</any>

In this case either of the category rules would fire with the class “VEHICLES” specified if any of the words were found in the classified document. Applied to the following:

We didn't know whether the wardrobe would fit in the car or if we would have to use Fred's pickup.

Both categories would fire giving:

...
<META name="VEHICLES" value="car" score="1.00" />
<META name="VEHICLES" value="truck" score="1.00" />
...
