I got interested in chatbot few months ago and looked at few open source implementations. so far, my findings are disappointing. the capabilities of those bots are very limited. I remember there was a post here saying they've built the first layer bot. I checked out. it turned out to be a menu system. for each question you ask, you have to select from few options by providing a number. sounds exactly like the auto phone support system. there are other deeplearning based ones I tried. but the replies they generated were very random...
