社会媒体在国际政治活动与日常社会生活中的巨大作用日益凸显，并以其传播速度快、覆盖面广、影响力大、渗透力强等特点对网络信息传播的可控性提出了严峻挑战。面对动辄上亿用户规模的社会媒体动态复杂系统，如何揭示信息传播演化规律并建立调控引导机制，已成为学术界及产业界共同面对的世界级难题。本项目针对社会媒体信息传播演化中存在的问题，利用课题组已有的数据资源和工作积累，以计算科学、社会学及心理学相关理论为支撑，从社会媒体信息的社会化分析、社会媒体信息的传播与演化机理以及社会媒体信息的牵制与引导机制等三个层面的问题为主要内容，通过对信息与社会二元空间融合建模、时空域融合的信息传播演化、复杂传播网络的牵制引导等关键技术的研究，为社会媒体信息传播的分析与引导提供技术支撑。力争实现社会媒体信息传播基础理论的创新，推动我国在媒体科学、网络科学、计算社会学等相关新兴领域的发展。

Social media plays an increasing role in international politics and daily life, because of its fast spread, wide coverage and influence, strong infiltration and other characters, it has posed a severe challenge to control the dissemination of network information. In the face of the dynamic and complex systems of social media with the scale of hundreds of millions of users, how to reveal the rule of information evolution and dissemination and establish the regulation and guidance mechanism, has been a world-calss challenge for academic and industry. According to the problems in the dissemination and evolution of social media information (SMI), this project utilizes existing data resources and working accumulation, based on computing science, sociology, psychology and related theories, and the main research content contains three aspects, from the socialization analysis of SMI, the dissemination and evolution mechanism of SMI, to the containment and guidance policy of SMI. The solutions of the key problems such as the fusion modeling of information and social dual space, the dissemination and evolution of spatiotemporal information, the containment and guidance of complex dissemination network, provides technical support for the analysis and guidance to the dissemination of SMI. This project strive to achieve basal theory innovation of the dissemination of SMI, and to promote the development of media science, network science, computing sociology and other related emerging field of our country.
