FACEBOOK has revealed how its ‘Trending Topics’ feature works after a report in the tech blog Gizmodo claimed that the social media giant downplays conservative news subjects.

Last week, Facebook denied that report, which relied upon a single anonymous individual with self-described conservative leanings.

In its own blog post, the company said a series of checks and balances - involving both software formulas and humans - ensures that stories displayed in the “trending topics” section are not biased. The post linked to a 28-page internal document Facebook uses to determine trending topics.

Facebook’s list of 1,000 news outlets contains several popular conservative sites, including Fox, the Drudge Report, Glenn Beck’s site The Blaze, the Daily Caller and the Washington Times.

Justin Osofsky, Facebook’s vice president of global operations, said the guidelines ensure that stories in trending topics represent “the most important popular stories, regardless of where they fall on the ideological spectrum.

The guidelines do not permit reviewers to add or suppress political perspectives.”

Mark Zuckerberg, co-founder and chief executive of the social media site, took to Facebook to say he plans to talk with leading conservatives in coming weeks. “I want to have a direct conversation about what Facebook stands for and how we can be sure our platform stays as open as possible,” he said in a statement.

Facebook has not said how many people are responsible for the trending topics team, although a report in the UK daily The Guardian said the team was as few as 12 people.

Trending topics were introduced in 2014 and appear in a separate section to the right of the Facebook newsfeed.

According to Facebook, potential trending topics are first determined by a software formula, or algorithm, that identifies topics that have spiked in popularity on the site.

Next, a team of trending topic staffers review potential topics and confirm the topic is tied to a current news event; write a topic description with information corroborated by at least three of 1,000 news outlets ; apply a category label to the topic; and check to see whether the topic is covered by most or all of ten major media outlets.

Stories covered by those outlets gain an importance level that may make them more likely to be seen.

Each Facebook user’s trending topics are then personalised via an algorithm that relies on information about the user such as “Likes” and their location.
