Vipshop is a leading online discount retailer for brands in China. The company offers high quality and popular branded products to consumers throughout China at a significant discount from retail prices. To optimize the shopping experience for their customers, the company built a personalized search recommendation system based on user query keywords and user portraits. Milvus, an open-source vector database built by Zilliz, is used to power the personalized recommender system on Vipshop’s mobile apps.
Build an e-commerce search recommendation system is to retrieve suitable products from a large number of products and display them to users according to their search intent and preference.
"At present, Milvus-based vector search can be used steadily in recommendation system scenarios, and its high performance gives us more room to play in the dimensionality of model and algorithm selection."
