What is sentiment analysis?
Sentiment analysis assigns an emotional polarity to text — typically positive, negative, or neutral — so teams can quantify how audiences feel about a topic over time.
Rule-based vs. AI models
Keyword lists break on sarcasm and mixed-language posts. Modern social listening uses language models that read full mention context before scoring.
How echole uses it
Each mention batch is scored during analysis. Sentiment shifts trigger alerts. Copilot can explain trends using the same underlying analysis record — not a separate black box.
