| 英文摘要 | In the pan geographic information age, with the development of the SoLoMo (social, local and mobile) modes in the mobile internet industry, how to effectively manage massive location-based data, social network and geospatial data has become a major challenge in the moving object databases field of research. In this paper, a spatial-temporal integrated data model for moving object trajectories and social relationships, called the Geo-Social-Moving (GSM) model, is proposed to manage both moving object geographical locations, trajectories and social relationships in an integrated framework. We define a series of common operations including interception, extension, projection and multi-dimensional projection. Then, the GSM model is implemented based on a graph database system. We conducted detailed experiments with two free location-based social network datasets from Brightkite and Gowalla to verified the effectiveness of the GSM model. Results show that the proposed GSM model can avoid query inefficiency caused by relational database table joins with the efficiency and stability to provide support for location-based social network applications. |
