This theory is proposed by Robin Dunbar [1], who is an anthropologist in Oxford University of UK. It is derived according to ape\u2019s intelligence and social networks. Dunbar\u2019s number ranges from 100 to 150, defining the size of the group in which every member knows each other. It is determined by human\u2019s mind capability. As the available capital of human\u2019s mind is a constant [2], the number of close relationships is limited. In fact, people will let weaker relationships dissipate and spend efforts to maintain a core group of fewer than 150 or so. [3] In order to maintain a close relationship, considerable investments are required in both emotion and psychology. <\/p>\n<p><strong>Statistics from Facebook<\/strong><br \/>\nFacebook\u2019s own statistics suggests that the average number of user\u2019s friends is about 130 [4], which is a fact that proves the theory of Dunbar\u2019s number. Although the number of friends of different Facebook\u2019s users is quite different (for example, some Facebook\u2019s users have more than 500 friends), actually, in personal lists of friends, the number of friends that users contact with frequently is quite small and relatively stable. The more actively and closely friends contact with others, the less and more stable the number of such a group is.  <\/p>\n<p><strong>Relevance to Our Project<\/strong><br \/>\nOur social networking application based on mobile contacts aims to strength the interactions and relationships with user\u2019s closest friends by ranking user\u2019s social networks\u2019 information. How to define user\u2019s closest friends? Dunbar\u2019s number tells us that most friends on our social networks are not people that we know and actually interact with most in real life. The closest friends are whom we care about and interact with in our daily lives and they are just in our contacts. Our project\u2019s main idea is to calculate the relationship degrees between user and user\u2019s contacts to quantify the relationships between user and contacts.<\/p>\n<p><strong> References:<\/strong><br \/>\n[1] R.
