Sentiment value is the positive, negative, neutral, or unknown sentiment for a post. Occasionally, the algorithm identifies positive and negative parts of a sentence and rates the post as neutral, because the amount of positive or negative text cancel each other out. You can edit and confirm sentiment values for individual posts to benefit from adaptive learning for your organization's sentiment algorithm. An unknown sentiment value indicates that the language isn’t supported by the sentiment algorithm. For more information on supported languages, download the Microsoft Social Engagement Translation Guide.

The sentiment index is calculated from the sentiment value of posts and normalized to a value between -10 and 10. All your active filters and parameters are considered to define the data set that the sentiment index calculates.

  • A sentiment index of 10 means that there are no negative posts in your data set.

  • A sentiment index of 0 means that there are equal amounts of positive and negative posts in your data set.

  • A sentiment index of -10 means that there are no positive posts in your data set.

Formula:

Sentiment index = (Positive posts – Negative posts)/(Positive posts + Negative posts) * 10
