watson_developer_cloud.tone_analyzer_v3 module

The IBM Watson™ Tone Analyzer service uses linguistic analysis to detect emotional and language tones in written text. The service can analyze tone at both the document and sentence levels. You can use the service to understand how your written communications are perceived and then to improve the tone of your communications. Businesses can use the service to learn the tone of their customers’ communications and to respond to each customer appropriately, or to understand and improve their customer conversations. Note: Request logging is disabled for the Tone Analyzer service. Regardless of whether you set the X-Watson-Learning-Opt-Out request header, the service does not log or retain data from requests and responses.

The score for the tone in the range of 0.5 to 1. A score greater

than 0.75 indicates a high likelihood that the tone is perceived in the utterance. :attr str tone_id: The unique, non-localized identifier of the tone for the results.

Bases: object

ToneScore.

Attr float score

The score for the tone.

• `2017-09-21`: The score that is returned lies in the range of 0.5 to 1. A score

greater than 0.75 indicates a high likelihood that the tone is perceived in the content. * `2016-05-19`: The score that is returned lies in the range of 0 to 1. A score less than 0.5 indicates that the tone is unlikely to be perceived in the content; a score greater than 0.75 indicates a high likelihood that the tone is perceived. :attr str tone_id: The unique, non-localized identifier of the tone. * `2017-09-21`: The service can return results for the following tone IDs: anger, fear, joy, and sadness (emotional tones); analytical, confident, and tentative (language tones).
