Term Frequency–Inverse Document Frequency: The Nerdy Way Facebook Sorts Graph Searches

(Before It's News)

In SoMeIT (Social Media Information Technology), we are fully dedicated to satisfying all of your web needs, integrating your business to social networks.

Ask Facebook Graph Search for “books liked by founders” and you won’t see The Da Vinci Code or The Bible first, though they’re amongst the most Liked books. Instead you’ll see books disproportionately Liked by founders compared to the general population thanks to “Term Frequency–Inverse Document Frequency”. Surfacing The Tipping Point, and Design For Hackers shows how smart Graph Search is.
