Examples¶

A parameter set designed to do incremental search for a person.¶

The question that is supposed to get an answer from a findout is the WH-question over the predicate "person". The parameter source is set to service, which means that a http service query will be used to find possible answers to the question. Incremental search is activated. The maximum number of hits that will be reported to the user is 10.

  <parameters question_type="wh_question" predicate="person" graphical_type="list"
              source="service" incremental="true" max_reported_hit_count="10">
    <ask_feature predicate="person_name"/>
    <ask_feature predicate="person_city" kpq="true"/>
    <ask_feature predicate="person_area"/>
  </parameters>

A parameter set designed to do be able to include parameters in an answer.¶

  <parameters predicate="ingredient_quantity">
    <background predicate="unit"/>
    <background predicate="selected_ingredient"/>
  </parameters>

A parameter set that includes a hint for answering a particular question.¶

If a user answers "I don't know" to a particular question, the hint defined using this element will be executed. The recommended child element of a hint is inform.

  <parameters predicate="ingredient_quantity">
    <hint>
        <inform>
            <proposition predicate="help_information_on_subject" value="hint_on_quantity"/>
        </inform>
    </hint>
  </parameters>

A parameter set that includes a hint for answering a particular yes/no question.¶

If a user answers "I don't know" to a particular yes/no question, the hint defined using this element will be executed. The recommended child element of a hint is inform.

  <parameters question_type="yn_question" predicate="add_sugar">
    <hint>
        <inform>
            <proposition predicate="help_information_on_subject" value="hint_on_adding_sugar"/>
        </inform>
    </hint>
  </parameters>

A Parameter Set that Indicates that Asking a Question about a Word Meaning is Always Relevant¶

  <parameters question_type="wh_question" predicate="word_meaning">
    <always_relevant/>
  </parameters>
