This topic covers the configuration of the sentiment analysis feature of the Discourse AI plugin.
Required user level: Administrator
Sentiment Analysis helps you keep tabs on your community by analyzing posts and providing sentiment and emotional scores to give you an overall sense of your community for any period of time. These insights can be helpful in determining the type of users posting within your community and interacting with one another.
To access the sentiment analysis for your community, go to Admin > Dashboard > Sentiment
Sentiment Analysis metrics can also be accessed through Data Explorer queries.

FAQs
Q: How is topic/post data processed? How are scores assigned?
A: Sentiment analysis has a “per post” fidelity. For each post we are able to tell sentiment and then cut that data in many shapes (per tag / category / time etc… )
Q: When Sentiment Analysis is enabled, does it go through all previous posts or just new ones?
A: A backfill task must be initiated to go through all previous posts
Q: Are there any plans to add support for other languages?
A: In the future Yes! both by adding multilingual simple Machine Learning (ML) models and by using multilingual Large Language Models (LLMs) to classify the data instead of dedicated models
Note that sentiment analysis is an area of experimentation and is changing rapidly as we add new UI elements and improve the feature based on feedback.
