Reviews: Paraphrase Generation with Latent Bag of Words

The paper proposes a two-stage model for sentence-level paraphrase generation, trained end-to-end. The first stage is content planning (specifically predicting a'latent' bag of keywords). The second one is the surface realization stage (forming a sentence relying on the keywords). The model is interesting and novel. The evaluation is sufficiently convincing (the author response, I believe, addressed initial concerns of the reviewer 1).
