Information Diffusion Model Based on Opportunity, Trust and Motivation

Abstract

Building an accurate information diffusion model around universal social factors has started to post its popularity on social network researches, which benefits a lot from its evolution simulation for identifying the messages with better prices, promoting news online quickly, and controlling public opinions. This paper constructs a novel model with respect to combine three factors: Opportunity, Social Trust and Game Selection Motivation. Firstly, the interest similarity between two users is convenient for measuring the opportunity to receive a message. Secondly, the threshold of social trust is calculated by coupling users network influence and content contribution. Thirdly, game selection with a rule to compute the best benefits has recognized as the motivation of users to spread a message. Finally, this paper presents an improved page rank algorithm to build a model by the idea of the game selection based on opportunity and social trust. Experimental result shows that social trust can accelerate the spread of information in Microblog social network by considering both the network topology and information content simultaneously.
