让chatbot(wit.ai)答复它没有正确答案 [英] Make chatbot (wit.ai) reply that it doesn't have a proper answer

问题描述

我正在将Wit.ai用于我的聊天机器人.问题是我的机器人总是试图回答一些问题.如果机器人真正理解了所要询问的内容，我只会做出回答.我知道这是有可能的，但是如果我的机器人没有多少回复，即使被问到完全不同的东西，它似乎总是会选择其中一个回复.

I am using Wit.ai for my chatbot. The problem is that my bot always tries to answer something. I will only make my bot answer if it actually understood what was being asked. I know it is possible, but if I have a bot with very few replies, it seems it always chooses one of the replies even though it is asked something completely different.

我想可以让它回复诸如对不起.我不知道您在问什么.我可以帮助您....."之类的东西.

I imagine it is possible to make it reply something like "I am sorry. I don't know what you are asking. I can help you with .....".

也许我应该使用可以检索的置信度值，并确保它在某个阈值之上?

Maybe I should use the confidence value that I can retrieve, and make sure it's above some threshold?

推荐答案

现在，解决此问题的最佳方法是使用范围外的请求创建一个或多个故事，并使用用户消息的策略特征"(更多详细信息，请此处) .

Right now the best way to deal with this problem is to create one or more stories with out-of-scope requests, and add a "catchall" entity with strategy "trait" to the user message (more details here).

在最简单的情况下，"catchall"实体将具有单个值.您可能有多个值，例如，如果您想要针对不同种类的范围外请求提供不同种类的答案，但是请记住，机器人越复杂，则需要编写的故事和数据就越多.它工作正常.

In the simplest case, your "catchall" entity will have a single value. You could have several values, for example if you want different kind of answers for different kind of out-of-scope requests, but keep in mind that the more complex your bot is, the more stories and data you will need to have to make it working correctly.
