  • TLDR:Cross-dataset analysis shows that semantic chunking improves extraction datasets with explicit relation cues, such as GM-CIHT and DDI, while fixed chunking remains competitive or stronger for dense biochemical extraction and binary classification settings such as ChemProt and ADE.

  • 标题中文:RAG 中面向生物医学信息抽取的可配置语义分块
  • TLDR中文:跨数据集分析表明,语义切分在具有显式关系线索的抽取数据集(如 GM-CIHT 和 DDI)上表现更优,而固定切分在密集生化抽取和二分类场景(如 ChemProt 和 ADE)下仍具竞争力甚至更强。
