Facebook makes changes to its Trending Topics team （375words）
By Hannah Kuchler in San Francisco
* * *
Facebook has made changes to how its Trending Topics team functions, in response to accusation that it has previously suppressed rightwing news and views that were popular on the platform.
In a letter responding to a Republican senator’s questions about Trending Topics, Facebook wrote that it would stop using a list of top-10 media outlets as a barometer for the importance of a story and would abandon a list of a thousand sources it relied upon to identify news.
After conducting an internal investigation, the social network also pledged to institute “additional controls and oversight” around the team that oversees the algorithm compiling the list of popular stories on the site.
Facebook said it had already updated the “terminology” in its guidelines, so it no longer talks about “injecting” or “boosting” topics, but instead says “topic correction”, for rewriting headlines, and “prominence”, for deciding if a story is national or major. It has provided refresher training for all topic reviewers.
“Our investigation has revealed no evidence of systematic political bias in the selection or prominence of stories included in the Trending Topics feature,” wrote Colin Stretch, Facebook’s general counsel in the letter to Republican senator John Thune.
“At the same time, as you would expect with an inquiry of this nature, our investigation could not exclude the possibility of isolated improper actions or unintentional bias in the implementation of our guidelines or policies.”
Facebook has come under pressure to explain how the Trending Topics team works after a report in technology blog Gizmodo claimed that reviewers, meant to be objectively overseeing an algorithm, were actually encouraged to exclude conservative topics from the list.
In the letter, Mr Stretch said that Ted Cruz had been featured in the list more than 160 times, Rand Paul more than 50 times and Mitt Romney more than 40 times. But he did not give comparative figures for people to the left of these politicians.
US conservatives were enraged by the story, with senator Thune writing to demand answers in his position as the chairman of the committee on commerce, science and transportation. Several rightwing commentators also criticised the site. Mark Zuckerberg, chief executive, last week invited several prominent conservatives to Facebook to explain how the feature works.
