The problem

Customer feedback was scattered across social platforms, marketplaces and surveys, with no way to read it as one signal or act on it in product decisions.

What was built

A sentiment classification engine that aggregates every channel and reports it against product lines.

Technical approach

Aggregation
Social media, e-commerce platforms and survey responses collected into one pipeline.
Classification
Naive Bayes, SVM and BERT models trained on the client's own labelled feedback.

Measurement framework

Deployment evidence is drawn from the published engagement. The delivery and measurement plans are case-specific recommendations grounded in the documented solution and results.

Evidence status
The source documents a deployed feedback-intelligence capability spanning customer channels, supported by reported changes in satisfaction, product quality and complaint volume.
Indicative delivery plan
Connect feedback channels, agree the sentiment and issue taxonomy, validate labelled samples, route insights to product and service owners, then monitor corrective actions.
Recommended baseline
Recommended: a matched pre-deployment period for customer-satisfaction score, product-quality indicators and complaint volume across the same social, marketplace and survey channels.
Recommended measurement method
Use a phased rollout or matched-period comparison with stable category definitions. Audit a stratified sample for precision and recall, then link operational changes to dated product or service actions rather than model output alone.

Recommended items are not presented as the original study method. They should be replaced with the confirmed project methodology when the underlying records are approved for publication.
