DataBuddy 如何用本体与语义层回答企业 AI 语义架构问题

一句话里，藏着两个层级的问题某公司的周会上，运营总监问了 AI 助手一句话：「上个月华东区客户的 DAU 是多少？」一句话，十二个字，听上去没什么刁难的意思，每个词你都觉得不会有歧义。按账号去重——一个人两个账号，算两个按**设备**去重——一人多端就算多个}]},{"type":"paragraph","attrs":{"id":"955d059f-1257-4726-9079-ad0c8074d2b1","textAlign":"inherit","indent":0,"color":null,"background":null,"isHoverDragHandle":false},"content":[{"type":"text","marks":[{"type":"textStyle","attrs":{"color":"","background":""}}],"text":"每换一种，数字都不一样。而三种都有正在跑的报表在用。"}]},{"type":"paragraph","attrs":{"id":"a233ce18-4655-49dd-8a7a-8f657f862f3b","textAlign":"inherit","indent":0,"color":null,"background":null,"isHoverDragHandle":false},"content":[{"type":"text","marks":[{"type":"textStyle","attrs":{"color":"","background":""}}],"text":"口径就是答案本身。同一个问题，换个算法就是另一个结论。"}]},{"type":"paragraph","attrs":{"id":"bc42b0c3-e731-43dd-bf1a-eac653b2d734","textAlign":"inherit","indent":0,"color":null,"background":null,"isHoverDragHandle":false},"content":[{"type":"text","marks":[{"type":"textStyle","attrs":{"color":"","background":""}}],"text":"这类问题问的其实是「这个数到底怎么算出来的」。这是语义模型该管的事：把「DAU」这个词钉成唯一一段计算逻辑，可预览、可验算、能追到血缘。"}]},{"type":"heading","attrs":{"id":"76244981-6ea1-481a-9063-8a73326fef12","textAlign":"inherit","indent":0,"level":2,"isHoverDragHandle":false},"content":[{"type":"text","marks":[{"type":"textStyle","attrs":{"color":"rgb(0,
