E2Rank unifies text embedding and reranking for efficient search

研究人员开发了E2Rank,一个新颖的框架,它统一了文本嵌入和列表式重排,以实现更有效和高效的搜索。该方法通过将重排提示视为伪相关反馈查询,将单一文本嵌入模型扩展到执行检索和重排。E2Rank在BEIR基准测试上取得了最先进的结果,在BRIGHT上表现具有竞争力,并且延迟显著低于现有的基于LLM的重排器,同时还提高了MTEB上的嵌入性能。 AI

影响 这项研究通过结合嵌入和重排技术,有望带来更高效、更准确的搜索系统。

    E2Rank:统一文本嵌入和列表重排以实现高效搜索

    arXiv:2510.22733v3 Announce Type: replace Abstract: Text embedding models deliver competitive retrieval performance with high efficiency, but their ranking fidelity remains limited compared to LLM-based listwise rerankers, which capture fine-grained query-document and document-do…
