Abstract: Provided is a method, apparatus, device and storage medium for determining a center vertex in a social network. The method includes steps described below. Multiple first vertices with a target attribute in the social network are determined; multiple sub-social sets are determined, where each sub-social set comprises one first vertex; a connected branch set corresponding to the each sub-social set is determined, where the connected branch set corresponding to the each sub-social set is a set of connected branches in a graph formed by vertices associated with the each sub-social set and lacking the target attribute; centrality of the first vertex comprised in the each sub-social set is obtained according to the each sub-social set and the connected branch set corresponding to the each sub-social set; and a first vertex with centrality satisfying a preset centrality requirement from the multiple first vertices is selected as the center vertex.

Abstract: Discloses are an APP pushing method and a computer-readable storage medium. Information of address book of each of a plurality of user terminals installed with a preset APP is obtained. All identical communication numbers present in detected address books of the plurality of user terminals are obtained. An intimacy set between a friend user corresponding to each identical communication number and terminal users corresponding to the plurality of user terminals is obtained according to interaction data between the friend user and the terminal users. At least one intimacy set with a number of close relationships matching a predetermined relationship being greater than a threshold is extracted from all intimacy sets. At least one of the preset APP and related information of the preset APP is pushed to the corresponding user terminal of the friend user corresponding to each intimacy set in the extracted at least one intimacy set.
