Using aspect extraction approaches to generate review summaries and user profiles
arXiv preprint arXiv:1804.08666, 2018•arxiv.org
Reviews of products or services on Internet marketplace websites contain a rich amount of
information. Users often wish to survey reviews or review snippets from the perspective of a
certain aspect, which has resulted in a large body of work on aspect identification and
extraction from such corpora. In this work, we evaluate a newly-proposed neural model for
aspect extraction on two practical tasks. The first is to extract canonical sentences of various
aspects from reviews, and is judged by human evaluators against alternatives. A $ k …

Reviews of products or services on Internet marketplace websites contain a rich amount of information. Users often wish to survey reviews or review snippets from the perspective of a certain aspect, which has resulted in a large body of work on aspect identification and extraction from such corpora. In this work, we evaluate a newly-proposed neural model for aspect extraction on two practical tasks. The first is to extract canonical sentences of various aspects from reviews, and is judged by human evaluators against alternatives. A -means baseline does remarkably well in this setting. The second experiment focuses on the suitability of the recovered aspect distributions to represent users by the reviews they have written. Through a set of review reranking experiments, we find that aspect-based profiles can largely capture notions of user preferences, by showing that divergent users generate markedly different review rankings.
