Thought many of you would find of interest my piece this morning mapping the geography of Facebook's list of the 1,000 media outlets it uses for its Trending Topics. The map on the second page may be of especial interest. Its striking to see the heavy absence of even English language African and Middle Eastern news outlets, even outlets like AllAfrica, as well as its reliance on RSS feeds, which have largely been depreciated in the online news space: http://www.forbes.com/sites/kalevleetaru/2016/05/13/is-facebooks-trending-to... Facebook confirmed to me by email that the list of news outlets they use was provided as-is by comScore, which claims to cover only 44 countries with that media product and I've reached out to them for comment on why their coverage of the region is so poor in the list they provided Facebook. But, thought many of you would find of great interest. To me all of the conversation about conservative/liberal bias masks what I see as the even greater issue, which is the Western bias in the information streams that are increasingly filtering the world around us. As well as how Silicon Valley companies build services like Trending Topics on top of various datasets without deeply understanding their biases and limitations or at least being transparent about the inputs and filters they are using. Those of you using large teams of human reviewers might also like my previous piece, which looks at the unconscious bias and the apparently lack of inter/intracoder reliability assessment in Facebook's operations: http://www.forbes.com/sites/kalevleetaru/2016/05/12/does-facebook-suffer-fro... ~K http://kalevleetaru.com/ http://blog.gdeltproject.org/
