Definition¶

<action name="action_name">

The grammar entry of an action. Defines how the system and the user can speak about and request actions.

Children¶

• <one-of>
  • <item>
    • <slot>
    • <vp>
      • <infinitive>
      • <imperative>
      • <ing-form>

Behaviour¶

The <action> element in the grammar defines the way in which the system and users can speak about a given action. The attribute name indicates which action in the ontology the grammar entry is for.

An action entry in the grammar should cover the different ways a user could speak about the action, such as different expressions and word choices. These options are given using the <one-of> tag, where each alternative expression is an <item>. <item> tags can contain <vp> or <slot> tags.

Examples¶

Action entry for setting an alarm with three different expressions:¶

<action name="set_alarm">
  <one-of>
    <item>set the alarm</item>
    <item>set alarm</item>
    <item>alarm</item>
  </one-of>
</action>

Action entry containing expression with <slot> tag:¶

<action name="set_alarm">
  <one-of>
    <item>set the alarm</item>
    <item>set alarm</item>
    <item>set the alarm to <slot predicate="time_to_set" type="individual"/></item>
  </one-of>
</action>
