In terms of the presentation, mathematical details of how the embeddings are computed are not sufficiently clear. While the authors have done an extensive evaluation, they haven't actually compared the system with an RL-based dialogue manager which is current state-of-the-art in goal-oriented systems. Finally, it is not clear how this approach scales to more complex problems. The authors say that the KB is 3K, but actually what the agent operates is about 10 (judging from Table 6).
- General Discussion: Overall, I think this is a good paper. Had the theoretical aspects of the paper been better presented I would give this paper an accept.
