Information propagation model based on online social network and propagation method thereof

Abstract

The invention requests the protection for a information propagation model based on online social network and propagation method thereof, and belongs to the field of online social network analysis. The information propagation model is composed of accessing to the data source, building dimensional attribute driving mechanism and building dynamic evolution strategy, building hot topic propagation model. The first step, the data source is accessed. The second step, dimensional attribute driving mechanism is built, user attributes is extracted from two aspects of network structure and user history, and the effects the two factors have to the driver of the user's participation in the topic are stated quantitatively through utilizing multiple linear regression methods. The third step, dynamic evolution strategy is built, income matrix is defined and popularity is perceived, and according to evolutionary game theory, building dynamic evolution strategy. The fourth step, hot topic propagation model is built. The user multidimensional attribute model, dynamic evolution strategy and traditional SIR model build a novel hot topic propagation model. The invention has the advantages of being effective to describe the spread of trend hot information in social networks and reveal the influence of different driving factors on information dissemination.

Description

technical field [0001] The invention relates to the field of social network analysis, relates to the modeling of online social network information dissemination, and reveals the influence of different driving factors on information dissemination. Background technique [0002] The rapid development of Internet technology has prompted the emergence of various types of online social media, and has gradually become an important tool for people to obtain and share information, profoundly affecting and changing the way people live. Social networks provide people with a wide range of information sources, and the data left by users on the network has become an important data source for researchers. The problem of information dissemination in social networks has become a potential research direction and has attracted the attention of many researchers. The research on the information dissemination mode of social network can solve many practical problems, such as marketing, shopping w...

Problems solved by technology

Although many models describing the state of the group have been proposed, most of them ignore the influence of the dynamic point of view interaction behavior and the process of changing strategies among users in the process of information dissemination, as well as the multi-source problem of information dissemination.
