利用位置的虚拟社交网络地理骨干网提取

Extracting the Geographic Backbone of Location-based Social Network

  • 摘要: 目的 基于海量的中国大型社交网络新浪微博人际社交关系数据,利用用户的地理位置信息对人-人(人际)社交关系进行虚拟网络空间到物理空间的映射,形成地-地关系。以城市为尺度,对个体间的社交关系链进行聚合,构建城市-城市(城际)社交关系网。根据网络的全局异构和局部异构等拓扑特征以及城市空间的相互作用,提出了一种融合重力模型和信息熵技术的地理骨干网提取方法。该研究有助于揭示虚拟网络环境下的城市体系结构、城市辐射力、城市吸引力和开放程度等问题。

     

    Abstract: Objective Based on the massive amount of users social relationship and location information data col-lected from the largest social network website in China-SINA micro-blog,an inter-city geographic so-cial network was built from the aggregated inter-person linkages mapped from virtual space onto thephysical space.Considering about the topological characteristics such as the global and local heteroge-neity,and the spatial interactions among cities,a hybrid geographic backbone extraction approach isproposed which is drawn from the gravity model and information entropy theories.This research canincrease understanding of the structure of urban systems,radiant ability,attractiveness and opennessof cities in the virtual web society.
