Abstract: Network groups arc a virtual gathering but real group phenomenon with the rapid expansion of Internet users. Because of the Internet privacy and freedom, the Internet community can more really represent their own point of view aiming at a thing phenomenon. Psychological hrcnds Network is a comprehensive psychology, cloud computing, information retrieval,natural language processing,statistical theory and methods such as multi-disciplinary design of the intelligent model. Constructed the program flow at the core of the network group model of intelligent analysis of psychological trend in architecture, breaking the data stream programs to address the cloud computing model software hottleneck. Further researched the design and realization of the core module in intelligent analysis model structure. And the college students Internet Group's 30000 texts were used to test the model, the test showed that the model can efficiently realize the psychological trend of population characteristics of the network, give the user a real feelings through the cloud and the structural equation model.
