Real-time Product Matching and User Profiling System for Personalized Item Selection
The paper introduces a product‑matching and user‑profiling system that builds themed collections by comparing new items to cold‑start samples using a two‑stage similarity pipeline—exact edit‑distance and pHash checks followed by doc2vec and OCR‑based embeddings—and then profiles sellers with RFM and clustering to highlight attributes like recent C2C sales volume, achieving about 80 % precision in a license‑plate bidding scenario while outlining future fusion improvements.
