My manager recently asked me to create a chat bot for the company that helps end users solve their queries related to the product. However, as far as I know, the company has some already made word documents which contain info related to how various functionalities in the product work. There are multiple word documents. So I think I will have to use these documents as my data to train the chat bot. So my question is, does anyone have any idea how to approach this problem? Or is there any step by step guide available to tackle this in NLP? Please suggest something.
