  In this project we outline a modularized, scalable system for comparing
Amazon products in an interactive and informative way using efficient latent
variable models and dynamic visualization. We demonstrate how our system can
build on the structure and rich review information of Amazon products in order
to provide a fast, multifaceted, and intuitive comparison. By providing a
condensed per-topic comparison visualization to the user, we are able to
display aggregate information from the entire set of reviews while providing an
interface that is at least as compact as the "most helpful reviews" currently
displayed by Amazon, yet far more informative.
