Search Query Embeddings via User-behavior-driven Contrastive Learning (2025.naacl-industry)

Copied to clipboard

Challenge: Existing approaches to embed search queries are limited due to shortness and surface-level variations.
Approach: They propose a user-behavior-driven contrastive learning approach which directly aligns query embeddings according to user intent.
Outcome: The proposed model outperforms state-of-the-art text embedding models on real-world QU tasks while minimizing lexical similarities.
