Configuring sentiment score range


Only available versions of this content are shown in the dropdown

You can define a sentiment score range to specify the type of sentiment feedback that you receive: positive, negative, or neutral.

You define neutral sentiment within the available score range ( -1 to 1 ). Sentiments with a higher score than the neutral range are positive and with the lower score are negative. This setting is helpful when you need to comply with your business requirements and precisely adjust the sentiment ranges. For example, narrowing the negative score range helps to identify the most critical text-based content such as news feeds, emails, and postings on social media streams.
  1. In the Records panel, click Decision Text Analyzer .

  2. Click the Advanced tab.

  3. In the Sentiment settings section, enter the minimum and maximum score to define the score range for the neutral sentiment, or keep the default values -0.25 and 0.25.

    Do not define the neutral sentiment score range as -1 to 0 or 0 to 1 because these ranges interfere with sentiment analysis of input texts. The first score range excludes negative sentiment from sentiment analysis; the second score range excludes positive sentiment.

To understand this configuration, analyze the following text with the default sentiment score values: Your company provides very good service. Still, the prices are too high. I have a neutral opinion about you.

The first sentence has positive sentiment, the second negative, the last one neutral. The overall sentiment for the whole text is neutral because the sentiment score equals 0.03, which belongs to the neutral sentiment score range ( -0.25 to 0.25 ).
