Creation of a Bottom-Up model learning AI

There are tons of websites that offer you the ability to create a personality and background for a A.I. Chatbot that you can talk with. Something to make the discussions more personal, and I know a majority of the learning A.I. that are being created are of the Top-Down variety. So my question is, hopefully to those that are in the industry of making A.I., is it possible to take one of those Chatbot models that you make and use that in the creation of an learning A.I. that is of the Bottom-Up variety?
