Resumen de Facebook's biggest secret
For Karrie Karahalios and Cedric Langbort at the University of Illinois and Christian Sandvig at the University of Michigan, Facebook's influence is out of balance with one's understanding of how its algorithm works. So they are carrying out what they call a collaborative audit looking at the Facebook experiences of thousands of people to work out the underlying algorithmic rules. To do this they have created an app called FeedVis, which creates a stream of everything that one's friends are posting. In their first small study using FeedVis, the team found that most people--62%--didn't know that the News Feed is automatically curated, People were shocked that they weren't seeing everything their network posted. In cases where posts of close friends or family were excluded, many became upset. The work was presented at the Berkman Center at Harvard University last week.
