It seems like an old way to solve the problem. I would be quite surprised if it gave good results compared to recent advances such as the LSTM-based paper “A Neural Conversational Model” [0]. In fact, I doubt it is even competitive compared to Cleverbot.<p>It does try to compare itself with existing alternatives, but it does not characterize the pros and cons of each alternative and does not compare results.<p>(I am not an expert, but did take classes on the subject of pattern recognition and machine learning.)<p>[0]: <a href="http:&#x2F;&#x2F;arxiv.org&#x2F;pdf&#x2F;1506.05869v1.pdf" rel="nofollow">http:&#x2F;&#x2F;arxiv.org&#x2F;pdf&#x2F;1506.05869v1.pdf</a>
