Optimizing Meituan Search Ranking with BERT: Methods and Practices

The Meituan Search team boosted ranking relevance by training a domain‑specific BERT, applying data augmentation, brand‑sample optimization, knowledge‑graph fusion, multi‑task and pairwise fine‑tuning, joint end‑to‑end training with LambdaLoss ranking models, and compressing the model for low‑latency inference, delivering up to +925 BP offline accuracy gains and measurable CTR and NDCG improvements in production.
