Thank you Mr Bhavya,

But what i meant is that i want the bot to answer the user bye this querry :

-hi user_name

even if i didn’t mention the name of the user the training set … the bot should be able to respond

Hi, @hamzaghannem2 I would recommend taking a look this blog post it covers generalizing entity recognition including names.
