Method and system for predicting information popularity of social network

The invention belonging to the field of social network information analysis makes a request of protecting a method and system for predicting information popularity of a social network. The method comprises steps of data acquisition, attribute extraction, model construction and prediction analysis. An information dissemination network is refined by combining user relationships and node behavior data in a social network; attributes affecting the measure of propagation power are extracted by starting with an individual behavior dimension and a node interaction dimension and related definitions are provided; a dual-weighted social network is constructed again and a node propagating power in the network is measured based on an improved PageRank algorithm; and individual characteristics of an information publisher and forwarding characteristics of the information published within one hour are extracted by using the information as a center and training is carried out by using an LR classifierto obtain an information popularity prediction model. Therefore, the information popularity can be predicted effectively; and a network group event is found out timely and important propagation nodesin the information dissemination network are identified.

Modeling method of dynamic social network information propagation model

The invention provides a modeling method of a dynamic social network information propagation model. The modeling method of the dynamic social network information propagation model is characterized in that a network element dynamicity and a network structure dynamicity are introduced based on a static society network evolution game model; two kinds of the dynamicity are combined with a evolution game method for performing cooperative evolution game, thereby obtaining a final evolution stable state in information propagation and forming a dynamic social network cooperative evolution model. According to the modeling method, a special background in information propagation is combined. The modeling method is more similar with reality in social network evolution. Furthermore the network element dynamicity and the network structure dynamicity are combined so that the model is more reasonable. The modeling method has advantages of simple principle, clear flow and easy realization. The modeling method improves predication accuracy in network information propagation. Furthermore the modeling method supplies an effective model support in fields of public sentiment controlling, network group event predicating, enterprise advertisement input product propaganda strategy, etc.
