ALWAES: Automatic Location-Aware Correction System for Online Delivery Platforms
summary
ALWAES automatically detects and corrects merchant location errors by mining courier travel times from 10+ million orders, training a distance-estimation model, and cross-validating neighboring merchants instead of costly field surveys. The system integrates GPS, an ibeacon device and a software virtual beacon installed at merchants to reduce travel-time uncertainty, outperforms three baselines by 32–47%, and reports 3,846 hours saved across 35,005 orders while uncovering new erroneous locations (≈3% of merchants).
