Where do facebook intelligent lists come from?

On September 19th 2011, Facebook introduced "Intelligent Lists" which are Friends Lists (FL) automatically created and pre-filled based on users' and their contacts' profiles information (education, work, city of living, kin, etc.). In early 2011, we conducted a study on contact management in Facebook in order to understand users' real needs. Outcomes from this study suggest several recommendations, some of which can be found today in the Facebook Intelligent Lists. This paper provides explanations on the recent evolution in Facebook contact management. The user study involved 148 participants. From their Facebook accounts, we retrieved 340 Friends Lists and 347 family ties. In the overall, the study has led to numerous interesting outocomes. In this paper, we focus on those related to Friends Lists and, particularly, on recommendations that have not yet been implemented in Facebook.
