11.If you get your news from social media,you are faced with a daily number of hoaxes(惡搞),rumors,and misleading news.When it's all mixed in with reliable information from honest sources,the truth can be very hard to judge.In face,my research team's analysis of data from Columbia University's Emergent rumor tracker suggests this false information is just as likely as to spread crazily as reliable information.
Our research shows that in view of the structure of our social networks and our limited attention,it is unavoidable that some popular unconfirmed information will spread quickly,regardless of their quality.Even if individuals tend to share information of higher quality,the networks as a whole is not effective at telling the difference between reliable and fake information.This helps explain all the hoaxes we observe in the wild.Besides,our attention is limited.If we pay attention to a certain topic,more information on the topic will be produced.It's cheaper to fake information and pass it off as fact than it is to report actual truth.
We can make our fight against false news more efficiently if we better understand how false information spreads.If,for example,robots are responsible for many pieces of the false news,we can focus attention on detecting them.
To that end,our lab is building a platform called Hoaxy to track and monitor the spread of unreliable information on social media.That will give us real-world data,with which we can inform our imitated social networks.Then we can test possible approaches to fight false news.Hoaxy may also be able to show people how easy it is their opinion to be misrepresent by online information and how likely some of us are to share false news online.Hoaxy will join a set of tools in our Observatory on Social Media,which allows anyone to see how false information spread on the Internet…
It is necessary that we spend resources on the study of this phenomenon.We need all hands on decks:Computer scientists,social scientists,economists,journalists and industry partners must work together to flight against the spread of false information.
