论文摘要
手机服务支持者不断收集呼叫详细记录（CDR），作为包含电话用户时空痕迹的使用日志。我们为大型时空数据集提出了一个多层分层分析模型，并将其应用于CDR的社会特征，例如社交活动，人际关系和团体，从CDR进行逐步探索。这种方法利用CDR作为初始层的初步输入，并将连续层的分析结果添加到知识库中，以在后续层中使用，以探索更详细的社交特征。随后的每个层都使用以前层中的结果，从而促进了仅使用RAW CDR的单层方法发现更深入的社交特征。该模型始于探索社会特征的综合概述，并逐渐关注社会关系和群体的全面细节，这促进了一种新颖的方法，用于调查CDR数据集，以逐步探索人口稠密的城市中社会特征的逐步探索。
Cellphone service-providers continuously collect Call Detail Records (CDR) as a usage log containing spatio-temporal traces of phone users. We proposed a multi-layered hierarchical analytical model for large spatio-temporal datasets and applied that for the progressive exploration of social features of a city, e.g., social activities, relationships, and groups, from CDR. This approach utilizes CDR as the preliminary input for the initial layer, and analytical results from consecutive layers are added to the knowledge-base to be used in the subsequent layers to explore more detailed social features. Each subsequent layer uses the results from previous layers, facilitating the discovery of more in-depth social features not predictable in a single-layered approach using only raw CDR. This model starts with exploring aggregated overviews of the social features and gradually focuses on comprehensive details of social relationships and groups, which facilitates a novel approach for investigating CDR datasets for the progressive exploration of social features in a densely-populated city.
