English(EN) Mine and Refine: Optimizing Graded Relevance in E-commerce Semantic Search Retrieval

新框架提升电商语义搜索相关性

一篇新的研究论文介绍了一个名为“Mine and Refine”的两阶段对比学习训练框架,旨在改进电子商务中的语义搜索检索。该方法解决了诸如参与信号嘈杂、挖掘困难负样本的挑战以及不同相关性级别之间不稳定的相似度分数分离等问题。该框架利用轻量级LLM进行可扩展的标注,并采用标签感知监督对比学习和Circle Loss的多级扩展。在生产环境的电子商务搜索中部署该方法后,在用户参与度、总订单价值和整体相关性指标方面均显示出显著的改进。 AI

影响 该框架通过优化检索准确性,有望显著提高电子商务搜索系统的有效性和用户参与度。
