before it's published to the site
machine learning models analyze a
multitude of proprietary data points
including behavioral and purchasing
patterns the timing and frequency of
reviews alongside relationships to
reviewers customers submitted reports of
abuse and more large language models or
llms are leveraged alongside natural
language processing techniques to
analyze anomalies in this data that
might indicate that a review was
incentivized say with a gift card free
or some other form of reimbursement we
also use deep graph neural networks or
GNN which are able to analyze and
understand complex relationships and

beyond surface level information to
uncover hidden differences between
authentic and fake reviews the majority
of reviews pass Amazon's High bar for

we might inspect the product in our

at first glance any set of customer
reviews may appear similar with no
distinct features that would flag one as
more suspicious than the other they
might share similar attributes like
ratings length and even sentiment
showing that the customer was satisfied
with their purchase this is where we
often see external parties get fake
review detection wrong they have to make
a lot of assumptions about what's
leading to review Behavior without
having access to the rich data at Amazon
it's always day one this means we
continue to invent new ways to stop fake
reviews from entering our store and hold
Bad actors accountable to protect our
