社会性网络服务社区中人际节点空间关系研究

Interpersonal relationships are related to social infrastructure, organizational structure, and regions interconnections, and will significantly impact on the spread of politics and culture. In recent years, Internet-based social network services (SNS) have been formed. New SNN-based communities, which represent new types of interpersonal relationships, have been unexpected developed. These communities play more and more important roles in various social activities and can even directly influence the development direction of some events. This project addresses this very hot topic. It aims to develop an innovative SNS-based interpersonal network analysis model based on our preliminary study and fundamental research in Human Dynamics、Concentric Zone Theory、Geographical Theory. It will collect SNS data and conduct huge data-based case studies through identifying four types of interpersonal relationships. The outcomes of this study include two important rules: One is the coexistence of dispersion and concentration in spatial distribution，and another is complicated overlap of virtual group and reality layers in population structure. This project will prove that in the age of Web2.0, traditional Concentric Zone Theory and Geographical Theory need to improve, and can be improved in new dynamic environments. These outcomes will indirectly contribute to the social and economic development as well as community-based culture..Innovation:①The proposed SNS-based interpersonal network analysis model will be the first to integrate SNS study into geography research through applying advanced information technology such as graphic theory, and will therefore drive groundbreaking theoretical research in virtual-realistic geography. The analysis model will provide a completely new perspective of connecting groups and a new methodology for study of the spatial relationship of interpersonal nodes on SNS. The novelty of the proposed model not only provides the appropriate means to analyze a spatial relationship of interpersonal nodes on topic-based SNS, but also presents a new research technique for the superimposition of virtual group and reality layers..②The two important rules, which will be revealed in this project, are based on new techniques of pattern measure, concept drift and dynamic changing in SNS. The methodology to prove the two rules are therefore innovative breakthrough. No other researcher has use pattern and concept drift to describe SNS as proposed here. The idea is that the patterns of social networks are keeping change, and the interpersonal are keeping change too. We need to measure the changes of patterns to discover knowledge and predict objectives, so that to work out how to improve two rules..③This project will use data mining methods and will develop data-driving models to conduct spatial analysis of interpersonal nodes on SNS. These will help to discover rules, and provide dynamic expression, which is a new exploration in our research area.

人际关系与社会组织结构、区域间相互作用紧密相关，对政治与文化传播具有极大影响。近年来，基于社会性网络服务（SNS）社区建立起来的人际节点关系正产生着意想不到的效果，"受众"力量的推动甚至能决定事态的发展。其中，人际节点空间关系在其整个系统中不容小觑。可是SNS社区中人际节点空间关系的存在形态是怎样的，与以往相比发生了哪些变化以及实际意义如何，尚未得到充分的解释。本项目基于丰富而实时的SNS信息资源，以前期研究中已证明较具支撑力的人类动力学、圈层结构理论、地缘论为基点，开发一组社交网络中人际节点空间分析模型，以4个机缘关系的数万成员、几万至十几万好友、数百话题的人际节点空间关系为案例，揭示两个基本规律：空间分布上分散与集聚的并存规律，人群结构上虚拟群组与现实圈层的复杂叠合规律。本项目将证明传统地理圈层理论和地缘论在Web2.0时代的存在与变化并弥补其不足，间接应用于社会、经济、文化空间扩散。

与Web2.0时代紧密结合，选择传统地理学的“空间”这一经典论题为视角，确立了SNS社区广泛应用背景下人际节点空间关系的复杂新特征。研究方向是“信息社会的地理学”和“信息经济地理”。本项目已发表论文11篇，其中SCI检索论文1篇、核心期刊论文7篇、国际会议论文2篇。主要研究内容包括人际节点认知体系和应用体系两个领域。前者有：SNS社区人际节点等级特征研究；SNS社区人际节点空间关系的中心性研究；基于模糊社会网络中心性模型的SNS社区人际节点空间关系研究。后者有：教育主题SNS社区人际节点空间交流特征研究；体验性网络团购对城市商业空间组织的影响研究；城市节点间互联网信息联系通达性研究和其他相关领域的研究。取得的重要结果有：划分出SNS社区人际节点的等级，确定了节点等级特征及其影响因素；解释了不同类型SNS社区人际节点空间关系的中心性特征；给出了一个基于模糊图论的由“点分布”、“点间联系强度”和“点群凝聚与集聚”组成的模糊社会网络中心性模型，并验证了其有效性；得出教育主题SNS社区人际节点的空间交流特征；揭示了电子商业模式作用下的商业网点空间分布规律；计算出城市节点间互联网信息联系通达性水平；从人际节点空间关系研究出发，拓展了一个新的研究领域——信息通信技术基础上的空域资源有效使用与协同管理。本项目理论上构建了一系列关于SNS社区人际节点空间关系的数理模型，较完善地论证了SNS社区人际节点空间关系的等级特征、中心性复杂性特征，总结了SNS社区人际节点空间关系的基本规律，初步弥补了国内地理学对Web2.0时代传统地理学重要理论延伸性的研究欠缺。从理论上发展了地理空间关系原理，实现了半现实—半虚拟空间关系研究的一些新突破，为推动经济地理学的研究从有限空间类型向地理网络空间类型迈进提供了理论依据；从实践上为合理组织现实中人的空间流动和信息社会网络空间均衡发展提供了依据；从技术上为相关网站开发及新型商业模式建立提供了支持，扩大了信息经济地理学的影响。
