Abstract: A community discovery method is provided. The community discover method includes partitioning nodes in a social network into community nodes partitioned into n first communities, each of the n first communities being associated with a corresponding community label, the corresponding label of each of the community nodes initially indicating a first community from among the n first communities to which the community node belongs, and n being an integer greater than or equal to 2; updating the corresponding label of each community node comprised in the n first communities; and partitioning the community nodes into m second communities, each of the community nodes in each of the m second communities having a same label, and m being a positive integer less than n.

Abstract: An initial weight is configured for each kind of basic age data, an age weight of the user in different basic age data is obtained according to the initial weight and age similarity of the user in different kinds of basic age data, and the age with the largest age weight is determined as the age of the user.

Abstract: A method, apparatus and system for updating location information of an IP address are disclosed. The method includes: receiving an incoming call; searching a pre-stored location database for a location corresponding to the incoming call; searching a pre-stored log database for an IP address corresponding to the incoming call; and updating location information of the IP address stored in an IP database by the location searched out. The present disclosure may be applied when a service provider updates the location information of the IP address in the IP database. Thus, the problem that the location information in the IP database cannot be updated accurately in the prior art is solved.

Abstract: A method and a system for determining age of a user based on mass data are provided. The method includes: obtaining basic age data of the user, configuring an initial weight for the basic age data; obtaining an age weight of the user in different kinds of basic age data according to the initial weight and an age similarity of the user in the different kinds of basic age data; and searching the basic age data for an age with a largest age weight, determining the age with the largest age weight as an estimated age of the user. The method and system for determining age of the user based on mass data is able to improve accuracy of the determination of the age of the user.
