Can LLM Annotations Replace User Clicks for Learning to Rank?

Lulu Yu, Keping Bi, Jiafeng Guo +4

Large-scale supervised data is essential for training modern ranking models, but obtaining high-quality human annotations is costly. Click data has been widely used as a low-cost a…

Unbiased Learning to Rank with Query-Level Click Propensity Estimation: Beyond Pointwise Observation and Relevance

Lulu Yu, Keping Bi, Jiafeng Guo +3

Most existing unbiased learning-to-rank (ULTR) approaches are based on the user examination hypothesis, which assumes that users will click a result only if it is both relevant and…

Contextual Dual Learning Algorithm with Listwise Distillation for Unbiased Learning to Rank

Lulu Yu, Keping Bi, Shiyu Ni +1

Unbiased Learning to Rank (ULTR) aims to leverage biased implicit user feedback (e.g., click) to optimize an unbiased ranking model. The effectiveness of the existing ULTR methods…

Feature-Enhanced Network with Hybrid Debiasing Strategies for Unbiased Learning to Rank

Lulu Yu, Yiting Wang, Xiaojie Sun +2

Unbiased learning to rank (ULTR) aims to mitigate various biases existing in user clicks, such as position bias, trust bias, presentation bias, and learn an effective ranker. In th…
