I am playing with a large dataset of hotel reviews, which contains both positive and negative reviews (the reviews are labeled). I want to use this dataset to perform textual style transfer - given a positive review, output a negative review which address the same thing. For example, if the positive review mentioned how spacious the rooms are, I want the output to be a review that complains about the small and claustrophobic rooms.
However, I don't have positive review-negative review pairs for the training. I was thinking that maybe I could create those pairs myself, but I'm not sure what is the best way to do that. Simple heuristics like jaccard index and such didn't give the desired results.
