English(EN) Listwise Explanation of Embedding-Based Rankings via Semantic Chunk Grouping

新方法增强了密集嵌入排序器的可解释性

研究人员开发了一种名为ChunkGroupSHAP的新方法,以提高信息检索中使用的密集嵌入排序器的可解释性。该技术跨文档对语义相关的文本块进行聚类以创建共享特征,解决了词级别解释与密集表示之间的不匹配问题。在MS MARCO和FinQA等数据集上的实验表明,最佳解释粒度取决于排序器和语料库,这表明需要与表示粒度和语料库结构都保持一致的特征单元。 AI

影响 提高了检索系统的可解释性,可能有助于调试和增强AI驱动的搜索和推荐引擎的信任度。
