如何获得检测到的实体的置信度分数？

问题描述

当我调用 LUIS API 时，我会获得与我的意图相关的置信度分数。我也得到了一个实体列表，但我没有得到相应的置信度分数。我如何获得置信度分数？

解决方法

这在某种程度上取决于您调用 API 的方式（直接调用或使用某些连接器/识别器）。我的回答假设您是通过 URL 直接调用的。在这种情况下，您是否有信心将取决于实体的类型。像 Regex 或 List 实体这样的东西不会有信心，因为它们只有在 100% 匹配时才会被识别。如果您使用机器学习实体，您将获得置信度分数。不确定任何其他实体类型或功能。这是我的应用程序中的示例负载。你可以看到我有一个 orderNumberML 和一个 orderNumber 实体，前者是机器学习的，有一个置信度值，后者正则表达式没有。您必须进入 $instance 属性，因为顶级 json.prediction.entities 只会为您提供列表，而无需任何其他上下文。
