Identification of a broker-type leader in a social network

摘要

Techniques for identification of a broker-type leader in a social network based on network topology are described. According to various embodiments, an electronic sociograph is accessed, the electronic sociograph depicting a plurality of actors of an online social network service as nodes in the sociograph, and the sociograph including edges between the nodes representing relationships between the respective actors. Thereafter, a particular node in the sociograph corresponding to an information connector node between at least two distinct groups of the nodes in the sociograph is identified. A particular actor of the plurality of actors associated with the particular node is then classified as an information connector between at least two sub-networks of the actors of the online social network service.

主权项

1. A method comprising:
accessing an electronic sociograph depicting each actor from a plurality of actors of an online social network service as a respective node in the electronic sociograph, the electronic sociograph including at least one edge extending between a respective node pair, wherein an edge represents a relationship between respective actors that correspond with a given node pair; identifying, by a machine including a memory and at least one processor and based on a network topology of the electronic sociograph, a particular node in the electronic sociograph corresponding to an information connector node, the information connector node between at least two distinct groups of nodes in the electronic sociography, the at least two distinct groups of nodes comprises a first group of nodes and a second group of nodes; classifying a particular actor that corresponds with the particular node as an information connector between at least two sub-networks of the actors of the online social network service, the at least two sub-networks based on the at least two distinct groups of nodes identifying a content item associated with a social interaction signal from the information connector, wherein a source of the content item is one of the actors that corresponds to a node in the first group of nodes; displaying information describing the content item and the social interaction signal in a content feed viewable by at least one actor that corresponds to a respective node in the second group of nodes; and determining that the content item has been disseminated throughout the online social network service by at least a predetermined number of actors that correspond to respective nodes in the second group of nodes.
