Abstract: With the wide application of Internet and computer technology, online social networking service becomes one of the best means to keep contacts with old friends and to make new friends. However, there are still many shortages in Social Networking Services(SNS), such as user relationship deterioration and user loss. In order to solve these problems, this paper proposes a SNS website system based on “dormitory”. A module of user relationship mining is embedded to help users to get their potential friends in advance by weight and potential relationship updating. Experimental results show that this system achieves a good recommending accuracy.
