reformulation

在信息查询/对话系统语境中，指用户（通常在系统未能理解后）改写或重构自己的提问，使其更接近系统能理解的措辞或意图。

English Definition

"In information seeking and dialog systems, the act of a user restating or restructuring a query (often in response to system failure) to better match the system's understood intent or vocabulary."

用法说明 · 针对中文母语者

常出现在 search/IR、HCI 对话研究中。是评估对话系统易用性的关键指标——用户需要多少次 reformulation 才能成功？

常见错误

·误以为是用户主动改写——很多情况下是被系统'逼'出来的
·与 paraphrase（释义）混用——reformulation 强调在交互失败后的调整行为
