Define what sentiment refers to. A review may praise the product while criticizing delivery. Document-level classification compresses those views into one label, while aspect-level analysis aims to differ the targets. Choose the granularity that supports the intended use. Labels depend on context and annotation rules. Sarcasm, polite complaints, negation, and domain-specific language can confuse a model trained on different material. A sentence containing a positive word is not necessarily positive overall. Evaluate using messages from the actual channel and language. Inspect disagreements and uncertainty rather than automatically forcing every message into a confident category. For an imbalanced dataset, compare per-class precision and remember in addition to overall accuracy. Treat the result as one input to analysis. Trends can be affected by who leaves feedback, changes in response rates, and the topics people choose to discuss. Avoid equating the average sentiment of a small vocal group with the views of all users. Tanga ingero zifatika kugira ngo umugenzuzi ashobore gusobanukirwa n'imiterere y'ikiremwamuntu.

The example shows why the target and granularity of a label matter more than a simplistic positive/negative count.
