1. A computer-implemented method of generating review summaries, comprising:
receiving a plurality of user reviews describing a first product;
determining a first list of categories of user feedback;
determining a group latent variable representing semantic information for the plurality of user reviews;
determining a respective category latent variable for each category of the first list of categories using the group latent variable, each category latent variable representing category-specific information from the plurality of user reviews for a respective category of the first list of categories;
generating a first review latent variable for a first user review of the plurality of user reviews, the first review latent variable being generated using a first category latent variable of a first category of the first list of categories, the first review latent variable representing information of the first user review that is relevant to the first category;
generating, by a decoder, using the first review latent variable corresponding to the first category, a first summary of the first user review of the plurality of user reviews, the first summary being specific to the first category;
generating, by the decoder using a second review latent variable corresponding to a second category of the first list of categories, a second summary of the first user review of the plurality of user reviews, the second summary being specific to the second category; and
generating output data comprising the first summary and the second summary.
