Mining Worse and Better Opinions. Unsupervised and Agnostic Aggregation of Online Reviews
In this paper, we propose a novel approach for aggregating online reviews,

review content. We measure the adherence of a review content to the domain
terminology extracted from a review set. First, we demonstrate the
informativeness of the adherence metric with respect to the score associated
with a review. Then, we exploit the metric values to group reviews, according
to the opinions they express. Our experimental campaign has been carried out on
two large datasets collected from Booking and Amazon, respectively
