Understanding the Comments Report: Sentiments and Themes

Quantum Workplace uses text analytics to assign themes and sentiments to every comment left on your survey.

This article applies to Engagement Survey analytics. Learn more about theme and sentiment analysis in our Pulse analytics here.

In this article: 


Our software classifies every comment on the survey as either negative, positive, or neutral/mixed. We color code sentiment in the following ways: 

  • Negative (Red): represents things that employees don’t like, think can be improved, or both.  
  • Positive (Blue): represents things that employees like, think are going well, or both. 
  • Mixed/Neutral (Gray): represents things that employees have either mixed or neutral feelings about. 
  • Unclear (White): represents a comment that can't be confidently identified.

How does Quantum Workplace calculate sentiment? 

Quantum Workplace's sentiment model is an artificial neural network that learns how people assign sentiments to comments so the model can accurately and automatically assign sentiments.

Can I change the sentiment associated with a comment? 

Yes, admin users can change sentiment by clicking on the colored circle to the left of the comment and selecting the new sentiment. Anyone who has access to the comments report will see the new, correct sentiment that you've updated.  


Themes are topics related to the workplace. As an example, the phrases ‘maternity leave,’ ‘childcare,’ and ‘work and home life’ all relate to the theme of Work-Life Balance.

How does Quantum Workplace calculate themes?

Quantum Workplace's theming model is composed of several artificial neural networks that are individually trained with data generated by users. These neural networks work together and by consensus, assign a tag to a comment. 

How are themes displayed in the Comments Report?

Comment themes appear as tags below each comment. 


A bubble chart on the Comments report shows the aggregate analysis of comment themes. 

In this bubble chart, themes are placed along an x-axis that indicates net sentiment. The size of each bubble indicates how often a theme is brought up in comments, the larger the bubble, the more frequently the theme is brought up. 

Clicking the icon in the top-right corner allows you to view the chart in a full-screen view or download the chart in various formats.
