How a chat bot can understand the emotion of the user?
How could I know whether the user is feeling low or angry by understanding the text converstation.
Please provide some tools libraries that will be useful for building up this kind of chat bot.
If you're looking for a js package then I would recommend this package named Sentiment . I have implemented it in a simple api.ai chat bot and it works great .
