Technical FAQ

How is topic/post data processed? How are scores assigned?

  • Sentiment 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… ). It compares the number of posts classified as either positive or negative. These are calculated when positive or negative scores > the set threshold score.

When Sentiment is enabled, does it go through all previous posts or just new ones?

  • A backfill task must be initiated to go through all previous posts.

Are there any plans to add support for other languages?

  • 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.

Caveats

  • Posts classified as neutral (neither positive or negative) are not shown
  • Private messages (PMs) are excluded from calculations
