The IBM Watson™ Tone Analyzer Service uses linguistic analysis to detect three types of tones from written text: emotions, social tendencies, and writing style. Emotions identified include things like anger, fear, joy, sadness, and disgust. Identified social tendencies include things from the Big Five personality traits used by some psychologists. These include openness, conscientiousness, extraversion, agreeableness, and emotional range. Identified writing styles include confident, analytical, and tentative.
Input email and other written media into the Tone Analyzer service, and use the results to determine if your writing comes across with the emotional impact, social tone, and writing style that you want your intended audience to see.
If you are using Node-RED on Bluemix, in the Bluemix Dashboard select your Node-RED app and click on 'Connect new'. This will open a new window where you can select the Watson Tone Analyser service. Then you click on 'Create' a screen will show which asks for a restage, click on 'Restage' and wait a minute. When the application is started click on the Url to go to your Node-RED application.
Copy an inject node :
You must provide in Input of the Tone Analyser (msg.payload) either :
- a string
- a Node.js Buffer
The provided Flows file (see below) proposes you amongst 3 differents way to connect the Input of the Tone Analyser node:
- Function node : you directly specify the string in the msg.payload
- Drobox node : you use a Dropbox account that hold the text file you want to be processed
- Buffer : you can provide any text source in binary format, but it should be a Node.js Buffer. (ex : the HTTP REQUEST node using the binary mode)
Not in scope ## Connect a Dropbox node as input
To configure a Dropbox node please follow the Dropbox nodes setup procedure.
You can take a HTTP REQUEST node and configure it such :
- mode : GET
- URL : specify a valid URL where the text file is accessible
- Return : select Binary
Drag and drop a Tone Analyser node from the nodes palette, and wire it with your input node.
Add a Debug Node, and configure it to msg.response to see only the results data from the Tone Analyser node.
Now configure your Tone Analyser node by selecting in the dropdown list
- the Tones (All / Emotion / Social / Writing): by default All.
- the Sentences Flag (True / False) : by default the value is True
Availables options for Tones
Availables options for Sentences
- Tone Analyser Flow : illustrates all kind of inputs availables for the Tone Analyser node.
