Online reviews can have a substantial impact on the consumer decision-making process. That makes them crucial to firms and online marketplaces. Some sellers are sometimes tempted to manipulate ratings to give their products fake, positive reviews. As a result, it’s important for such marketplaces, like Amazon, to eliminate fake reviews. Some methods use metadata, review characteristics, text or images to remove such reviews. This may also flag legitimate ones, however. Researchers in this study found a method using the network structure of reviews to reveal fakes without wrongly targeting authentic ones.
