Text Analytics
Use the Text Analytics action to provide an advanced natural language processing over raw text that includes the following types of analysis:
• Language detection
• Sentiment analysis
• Key phrase extraction
• Entity recognition
For more information, see
Azure Text Analytics.
Complete the following steps to use the Text Analytics action in your workflow:
1. Drag the
Text Analytics action under
Azure to the canvas, place the pointer on the action, and then click
or double-click the action. The Text Analytics window opens.
2. Edit the Label, if needed. By default, the label name is the same as the action name.
If you previously added a connector type, select the appropriate Connector Type, and under Connector Name, select the connector.
4. Click TEST to validate the connector.
5. Click
MAP CONNECTOR to execute the action using a connector that is different from the one that you are using to populate the input fields. In the
Runtime Connector field, provide a valid Azure connector name. For more information about

If you selected Connector Type as None, the MAP CONNECTOR option is not available.

◦ Get Key Phrases—Detects the key phrases in the input text.
◦ Sentiment Analysis—Detects the sentiment of the text with a numeric score between 0 and 1. A score closer to 1 indicates a positive sentiment, and a score closer to 0 indicates a negative sentiment.
