English(EN) When the Text Is Silent: Memory Shortcuts and the Validity of LLM Annotation under Evidence Insufficiency

当文本证据缺失时，LLM的“记忆捷径”可能导致标注无效

作者 PulseAugur 编辑部 · [1 个来源] · 2026-11-04 05:00

一篇新的研究论文探讨了大型语言模型（LLM）在标注文本时出现的“记忆捷径”现象。研究发现，虽然LLM通常不会在现有知识与文本证据冲突时用现有知识替代文本证据，但它们在证据缺失时确实会表现出这种捷径。这可能导致标注在事实层面与主题相关，但却得不到所提供文本的支持，从而可能使研究无效。该论文建议，值得信赖的LLM标注需要进行审计，以测试证据缺失情况，考虑标注指令的激励因素，并评估缓解措施的权衡。 AI

影响强调了LLM辅助研究中潜在的方法论缺陷，并为可靠标注提出了新的审计技术。

当文本沉默时：证据不足情况下的记忆捷径与LLM标注的有效性

arXiv:2611.02273v1 Announce Type: cross Abstract: Large language models (LLMs) are increasingly used to annotate text for social science research, content moderation, and training data. Their broad knowledge of real-world entities raises a concern: when labeling a text, do they r…
