Towards Generalizable Semantic Product Search by Text Similarity Pre-training on Search Click Logs. (arXiv:2204.05231v2 [cs.IR] UPDATED)
cs.LG updates on arXiv.org arxiv.org
Recently, semantic search has been successfully applied to e-commerce product
search and the learned semantic space(s) for query and product encoding are
expected to generalize to unseen queries or products. Yet, whether
generalization can conveniently emerge has not been thoroughly studied in the
domain thus far. In this paper, we examine several general-domain and
domain-specific pre-trained Roberta variants and discover that general-domain
fine-tuning does not help generalization, which aligns with the discovery of
prior art. Proper domain-specific fine-tuning with clickstream …
