Q&A on Any Spreadsheet Requires Interpreting Its Grid Structure· LLM 驱动的表格问答框架
Semantic cell annotation improves chunking interpretability for spreadsheets in LLM-driven RAG systems, aiding answer generation through enriched context rather than improved retrieval accuracy. We propose a novel framework of splitting any spreadsheet into interpretable chunks using cell role annotation. Our framework beats the state of the art, yet it faces a hard ceiling. Spreadsheets are fundamentally two-dimensional unstructured data with continuous relationships and infinite potential cell roles. Because classification models are restricted to finite, pre-defined classes, they cannot perfectly capture this structural nuance, even with human-level annotation. We show that addressing the spreadsheet-to-LLM bottleneck requires moving beyond discrete cell classification. Instead, the fie

- 适合谁读
- 研究者 / 工程师
- 要解决的问题
- 现有 LLM 驱动的表格问答系统在处理表格时,无法有效解释表格的网格结构,导致生成的答案质量不高。
- 关键实验
- 通过多个表格数据集验证了新框架的有效性,但在某些复杂关系上的表现仍有局限。
- 主要贡献
- 该框架在性能上优于现有方法,但同时指出了单元格分类模型在处理表格结构上的局限性。
