Designing Reward Signals for Portable Query Generation: A Case Study in Industrial Semantic Job Search

Ping Liu, Qianqi Shen, Jianqiang Shen +11

Job-search platforms rely on low-bandwidth query interfaces that often fail to capture the high-dimensional complexity of candidate profiles. We present an end-to-end RLAIF (Reinfo…

Policy-Grounded Dynamic Facet Suggestions for Job Search

Dan Xu, Baofen Zheng, Qianqi Shen +11

Job seekers often initiate search with short, underspecified queries. At LinkedIn, over 80% of job-related queries contain three or fewer keywords, making accurate user intent infe…

Semantic Search At LinkedIn

Fedor Borisyuk, Sriram Vasudevan, Muchen Wu +71

Semantic search with large language models (LLMs) enables retrieval by meaning rather than keyword overlap, but scaling it requires major inference efficiency advances. We present…

Powering Job Search at Scale: LLM-Enhanced Query Understanding in Job Matching Systems

Ping Liu, Jianqiang Shen, Qianqi Shen +9

Query understanding is essential in modern relevance systems, where user queries are often short, ambiguous, and highly context-dependent. Traditional approaches often rely on mult…
