We tend to read the news feed every time when we login our Facebook, but have we ever wonder that how Facebook determines them? Social networking site have actually devised different algorithms to it. Apart from the other things like where you live and the pages you follow. The Facebook primarily looks for two broader signals- Topics that are being mentioned a lot and the topics that suddenly increased, reposted.
For instance Kim Kardashian, an American Model who is often mentioned in the Facebook. The total volume of mentions are always high and is not a good indicator of whether or not he is part of a trending topic. So, Facebook would look for a hike in mentions relative to the normal prattle around Kim Kardashian.
According to the reports “the things that trend are not just the most highly mentioned people or topics, instead they have to be tied to some kind of relevant event”. Once a topic is identified as trending, it is approved by a human controller, who edits and rewrites the description. These people don’t get to pick what Facebook adds to the trending section. This is done automatically by the algorithm. They just have to pick the headline.
