Sentiment Analysis
Classifying the tone or opinion expressed in text, often as positive, negative, neutral, or topic-specific sentiment.
Last reviewed August 4, 2026What it means in practice
Sentiment helps summarize volume, but sarcasm, context, selection bias, and mixed opinions make it directional rather than definitive.
If this term cannot change a decision, sharpen the question or gather better evidence before doing more analysis.
A concrete example
Review sentiment worsens specifically around support after a competitor changes service tiers, while product sentiment remains stable.
What to watch
Large text volumes
A suspected perception shift
Need to compare themes over time
How to use it well
- Start with the decision.Write down who needs to decide what, and by when.
- Separate evidence from interpretation.Keep the source, date, and observable fact attached to every conclusion.
- Turn the finding into a move.Update the message, battlecard, roadmap question, or watchlist—or explicitly choose not to react.
Common mistakes
Collecting without a question. More information creates more work unless it is tied to a decision.
Treating one signal as a strategy. Look for corroborating evidence and patterns before making a large response.
Losing the source. Unsourced competitive claims become stale, risky, and impossible for sales to defend.
