title: Is there any way to get a "type" of text from dialogflow
body: <p>In our chatbot we have a fallback intent but it would be great if I could know if the user was</p>
  <ol>
  <li>asking a question</li>
  <li>just saying arbitrary things like &quot;cool&quot;, &quot;ok&quot;, &quot;got it&quot;</li>
  <li>complaining (derogatory texts)</li>
  </ol>
  <p>I think (3) can be achieved with sentiment analysis, but is there a tool or an additional API that can guess this sort level of categorisation.</p>
  <p>These are chat texts so they are super short.</p>
