REDWOOD CITY, Calif.--(BUSINESS WIRE)--Jun 26, 2023--

E-commerce giant Amazon has said it uses artificial intelligence systems to prevent fake reviews on the platform that can intentionally mislead customers. While the company already uses machine learning models to detect risks such as links to other accounts, sign-in activity, review history, and other indications of unusual behavior that point to fake reviews, the tech giant said on Tuesday that is further investing in sophisticated fraud-detection tools. Using several such methods, the company said it “proactively blocked over 200 million suspected fake reviews” from its stores in 2022. “We will continue to build sophisticated tools that protect customers, our selling partners, and our store from bad actors that attempt to profit by proliferating fake reviews globally,” Amazon said. In the new statement, the e-commerce giant warned of the emergence of an illicit industry of “fake review brokers,” who approach consumers via social media channels, and messaging services, soliciting them to write fake reviews in exchange for money or other incentives. These brokers, according to Amazon, portray themselves as legitimate businesses with networks of hundreds of employees stationed worldwide. So far, it has taken legal action against over 90 such bad actors around the world who facilitated fake reviews and sued more than 10,000 Facebook group administrators who attempted to put fake reviews. It also reported over 23,000 abusive social media groups, with over 46 million members and followers, that facilitated fake reviews in 2022, the company added. These high-volume fake review brokers a “global problem” impacting multiple industries, according to Amazon, which called on the private sector, consumer groups, and governments to work together to stop fake review brokers. “Through cross-industry sharing – including information on bad actors’ tactics and techniques, who they are targeting, the services they provide, and how they operate – we can more effectively shut down these schemes, thereby protecting more consumers across different industries,” the company said. In countries that already have laws against soliciting fake reviews, it said regulators could do more to use their authority to take action against fake review brokers. “We also support greater funding for law enforcement to build further technical expertise to investigate and take down these brokers,” the multibillion-dollar conglomerate said. “Amazon will continue to protect our stores from fake reviews by investing in proactive tools to detect and stop fake reviews from impacting a customer’s buying decision,” it added.

To the uninitiated, there isn’t much to water. Sure, the world’s oceans are filled with monsters, marvels and mysteries but, otherwise, they’re just vast, singular expanses of liquid. Right? Wrong. Far from being uniform everywhere, ocean water is a patchwork of interlinked layers and masses which mix and split apart thanks to currents, eddies, and changes in temperature or salinity. Indeed, beneath the surfaces of our great seas, there are waterfalls, rivers and even gigantic blobs, stretching thousands of miles, that somehow manage to evade detection. Now, scientists have discovered one of these massive blobs in the middle of the Atlantic Ocean; extending from the tip of Brazil to the Gulf of Guinea. Until the discovery of this water mass – which has been named the Atlantic Equatorial Water – experts had seen waters mixing along the equator in the Pacific and Indian oceans, but never in the Atlantic. "It seemed controversial that the equatorial water mass is present in the Pacific and Indian oceans but missing in the Atlantic Ocean because the equatorial circulation and mixing in all three oceans have common features," Viktor Zhurbas, a physicist and oceanologist at The Shirshov Institute of Oceanology in Moscow, told Live Science. "The identified new water mass has allowed us to complete (or at least more accurately describe) the phenomenological pattern of basic water masses of the World Ocean." As the name suggests, the Atlantic Equatorial Water is formed by the mixing of separate bodies of water by currents along the equator. To distinguish such masses from the water surrounding them, oceanographers analyse the relationship between temperature and salinity across the ocean — which determines the density of the seawater. Back in 1942, this charting of temperature-salinity led to the discovery of equatorial waters in the Pacific and Indian oceans, as Live Science notes. Because they are created by the mixing of waters to the north and south, the Indian and Pacific Equatorial waters share similar temperatures and salinities curving along lines of constant density, which make them easy to distinguish from the surrounding water. And yet, for years, no such relationship could be spotted in the Atlantic. However, thanks to data collected by the Argo programme – an international collection of robotic, self-submerging floats which have been installed across Earth’s oceans – the researchers spotted an unnoticed temperature-salinity curve located parallel to the North Atlantic and South Atlantic Central waters. This was that elusive Atlantic Equatorial Water. "It was easy to confuse the Atlantic Equatorial Water with the South Atlantic Central Water, and in order to distinguish them it was necessary to have a fairly dense network of vertical temperature and salinity profiles covering the entire Atlantic Ocean," Zhurbas explained in his email to Live Science. The discovery is significant because it offers experts a better understanding of how oceans mix, which is vital to how they transport heat, oxygen and nutrients around the world.
