Unleashing the Power of LLMs in Dense Retrieval with Query Likelihood Modeling

no code implementations7 Apr 2025 Hengran Zhang, Keping Bi, Jiafeng Guo, Xiaojie Sun, Shihao Liu, Daiting Shi, Dawei Yin, Xueqi Cheng

Inspired by the classical word-based language modeling approach for IR, i. e., the query likelihood (QL) model, we seek to sufficiently utilize LLMs' generative ability by QL maximization.

Leveraging LLMs for Utility-Focused Annotation: Reducing Manual Effort for Retrieval and RAG

no code implementations7 Apr 2025 Hengran Zhang, Minghao Tang, Keping Bi, Jiafeng Guo, Shihao Liu, Daiting Shi, Dawei Yin, Xueqi Cheng

Therefore, we investigate utility-focused annotation via LLMs for large-scale retriever training data across both in-domain and out-of-domain settings on the retrieval and RAG tasks.

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

1 code implementation17 Feb 2025 Lulu Yu, Keping Bi, Jiafeng Guo, Shihao Liu, Dawei Yin

Motivated by this, we propose a query-level click propensity model to capture the probability that users will click on different result lists, allowing for non-zero probabilities that users may not click on an observed relevant result.

Generative Retrieval for Book search

no code implementations19 Jan 2025 Yubao Tang, Ruqing Zhang, Jiafeng Guo, Maarten de Rijke, Shihao Liu, Shuaiqing Wang, Dawei Yin, Xueqi Cheng

Directly applying GR to book search is a challenge due to the unique characteristics of book search: The model needs to retain the complex, multi-faceted information of the book, which increases the demand for labeled data.
