Just read this article at CNN

Raises the interesting topic as to how to use the pipelined data from reviews to find out they are “fraudulent/false” or “true/real” ?

An excerpt from the article raises interesting questions - How would a data scientist/analyst detect fake reviews ?

" An investigation earlier this year by UK consumer group Which? discovered a thriving industry of businesses making money by manipulating reviews on Amazon’s marketplace. One company had 62,000 reviewers globally — including 20,000 based in the United Kingdom — and would sell individual reviews for £13 ($18) or in bulk packages starting at £620 ($863) for 50 reviews."
