在线社会网络的网络结构和信息传播研究综述

随着在线社会网络的大规模应用和普及, 亟需对在线社会网络进行深入研究分析。在线社会网络的网络结构和信息传播研究是该领域中的两大研究热点和关键问题。网络结构包括关键节点、网络关系以及社团的挖掘, 通过对网络结构的分析可以掌握被分析网络中存在的社团、节点之间的关系以及关键节点等, 而这种分析对于国家及时掌握在线社会网络的舆情、公司广告在网络上投放策略的制定都具有极大的帮助。对在线社会网络信息传播的研究主要有信息传播动力模型、信息传播源和路径的发现与描绘、信息传播的最大化和最小化等, 通过对在线社会网络信息传播的研究, 人们可以对在线社会网络信息传播的影响进行预测和干预, 从而可以将信息传播的影响按照有利的方向引导。综述了在线社会网络的网络结构和信息传播的研究现状, 并对这两方面的主要研究方法及技术的优势和不足以及适用场合进行了对比分析。

Survey on network structure and infomation difussion of online social networks research

With the online social network is applied in large scale and popular, the deep researches on it are urgent needed. The network structure and information difussion are the hot topic in the field. Network structure research including key nodes, network relationships or communities detection, and the network structure can be analyzed to get the communities existing in the network, the relationship between nodes and key nodes, etc. , and which can provide the government information with the public opinion on online social networks, the company with network advertising strategy. Research on information difussion of the online social networks are mainly including dynamic information difussion model, source and path discovery of the information difussion, information dissemination to maximize and minimize, and through the research people can predict the impact of the information difussion and interfere it, so it can guide the information difussion in the way people hoped. This paper reviewed the researching on the network structure and information dissemination of online social network, and compared the advantage, disadvantage and the suitable area of the major research methods on the two aspects.
