<p>The Tone Analyzer service uses linguistic analysis to detect emotional tones, social propensities, and writing styles in written communication.</p>
63+
<p>The text to analyze should be passed in on <b>msg.payload</b>.</p>
64+
<p>The service response will be returned on <b>msg.response</b>.</p>
65+
<p>Usng the node editor dialog users can filter the results by tone (emotion, writing or social) and whether to include sentence-level analysis.</p>
66+
<p>For more information about the Tone Analyzer service, read the <a href="https://www.ibm.com/smarterplanet/us/en/ibmwatson/developercloud/tone-analyzer.html">documentation</a>.</p>
