How to identify the exact meaning of the user input?
We need to identify the exact meaning of the user input.
For example, if user inputs "I am never ever really ill", it should identify the person is "Healthy".
We tried by using NLU, actually, the sentence has a positive meaning that the user was never ill but the NLU API is returning Sentiment => Negative -0.81
Using which API (service) we can get this.
Rather than using Natural Language Understanding, you can train Intents in Watson Conversation or Natural Language Classifier.
NLU is pretty fine for what you intent... however, you need to create and associate a custom model where you can define that "Never ever really ill" and "Healthy" are the same type. This can be achieved using Knowledge Studio and then linking it to NLU.
