Design, Evaluation, and Production of a VOC Tagging System for Taobao User Experience

Taobao’s Technical Industry Data team designed a four‑level VOC tagging hierarchy to unify fragmented user‑feedback sources, evaluated label similarity with vector‑based distance matrices, optimized tag groups via entropy‑driven re‑grouping, built a stacking ensemble of FastText and TextCNN achieving over 90% accuracy, and deployed an automated production pipeline that generates tags, maintains ODPS tables, and provides APIs for rapid experimentation.

User Experience Analysis of Taobao Detail Page Using User Journey and VOC Data

The article, the second in a ten‑part Taobao APP UX series, explains how module‑level user‑journey metrics and Voice‑of‑Customer chat data are collected, labeled with a BIO‑CRF taxonomy, clustered via DBSCAN, and correlated to identify size and quality concerns on the men’s‑clothing detail page, prompting module redesigns, A/B tests, and resulting in higher conversion rates and reduced dwell time.
