METHOD AND SYSTEM FOR EXCAVATING TOPIC CORE CIRCLE IN SOCIAL NETWORK

摘要

The embodiments of the present invention are applied to the field of social networks, and provided are a method and system for excavating a topic core circle in a social network. The method comprises: constructing a social network diagram, the social network diagram containing a plurality of nodes which are connected to each other; selecting one node from the social network diagram as a first node of the core circle, plotting into the core circle a second node most connected to the first node, plotting into the core circle a third node outside the core circle which is most connected to the nodes in the core circle, and so on until the Nth node outside the core circle is plotted into the core circle, N being the preset number of nodes contained in the core circle; and conducting topic aggregation on the core circle containing N nodes, and obtaining a topic concerned by each node in the core circle containing N nodes. The embodiments of the present invention can be applied to effectively excavate core circles which have similar topics and close contact in a social network.
