Passage-specific Prompt Tuning for Passage Reranking in Question Answering with Large Language Models

no code implementations31 May 2024 Xuyang Wu, Zhiyuan Peng, Sravanthi Rajanala, Hsin-Tai Wu, Yi Fang

In this paper, we propose passage-specific prompt tuning for reranking in open-domain question answering (PSPT): a parameter-efficient method that fine-tunes learnable passage-specific soft prompts, incorporating passage-specific knowledge from a limited set of question-passage relevance pairs.

Do Large Language Models Rank Fairly? An Empirical Study on the Fairness of LLMs as Rankers

no code implementations4 Apr 2024 YuAn Wang, Xuyang Wu, Hsin-Tai Wu, Zhiqiang Tao, Yi Fang

The integration of Large Language Models (LLMs) in information retrieval has raised a critical reevaluation of fairness in the text-ranking models.
