Amazon to Improve Customer Reviews With Machine Learning

Amazon.com is rolling out a big change to its customer reviews system in the U.S., introducing a new machine-learning platform it developed in-house to surface newer and more helpful reviews. The change, which started Friday, will probably go unnoticed at first, as the e-commerce giant's new platform gradually starts altering the star ratings and top reviews on product pages. The new system will give more weight to newer reviews, reviews from verified Amazon purchasers and those that more customers vote up as being helpful.
