Research about rumors spreading on web is a hot topic in internet public opinions research area. The main purpose to study rumors spreading on web in group polarization condition is to discuss the disorder change of social system and to reveal the micro-dynamics of rumor spreading in group polarization, because group polarization is one of typical characters of the rumors spreading process on web, one of typical netizens’behaviors those affected by rumors and the main reason why web rumors are able to seriously damage the public order.In this paper, the social origins of group polarization were analyzed and a Double-Engine model for group polarization was established. The model could describe the process of group polarization in real world reasonably and reveal that the essence of group polarization was a node’s attitude incremental positive feedback mechanism which generated by the synergy from information collaborative filtering and the Spiral of Silence. This research proved that, in group polarization, the initial condition could be decisive to the result of system working. This paper was made an improvement based on exist centralization indexes by establishing an Opinion Leader’s relative influential factor (OLRIF). The result of simulation proved that to clarify in time and to clarify on a popular media platform could be quite important to prevent group polarization and rumors spreading. Information entropy was been used to evaluate the disorder of system during rumors spreading in group polarization. This paper discussed the influence on social system disorder and senses of netizens from group polarization, simulated the damage to the social order from rumors spreading in group polarization, and proved that efficiency of clarification and to trace and clarify rumors in time could be positive to restrain rumors spreading.In this paper, a Double-Engine model for group polarization was established. The model enhanced the theory of rumors spreading by setting up attitude factor, describing quantificationally the theories of information collaborative filtering and Spiral of Silence and deducing the principle of node’s attitude incremental positive feedback mechanism. According to the insufficient of exist influence indexes to describe rumors spreading in group polarization, an OLRIF was established and the evaluating algorithm was given to improve evaluation of node’s influence in rumors spreading web. An information entropy based rumors spreading model was established by using information entropy to evaluate system disorder. This paper improved traditional rumors spreading models for discussing the influence on group polarization from system disorder, adding an external minus attitude increment input for simulating official clarification.To Chinese government, to manage rumors on web efficiently could be an inevitable challenge during the process of constructing the harmonious socialist society in China. The management policies of making the Internet public opinion supervision system better, using unofficial clarification platform, making the mainstream media play a primordial role in clarification, improve the government information disclosure and strengthen netizens’information literacy began to be paid more attention to by the government and the researchers. The mechanism of rumors on web would be constantly improved to ensure social atmosphere harmonious and to promote constructing spiritual civilization effectively.
