摘要:

时空数据采掘(STDM)从空间和时间之间的动态相互作用中发现有用的模式。几个可用的调查捕捉STDM的进步,并报告了在这一领域的重要进展财富。然而,STDM的挑战和问题并没有在他们自己的文章中进行彻底的讨论和介绍。我们试图填补这一空白,提供一个全面的文献调查国家的最先进的进展,STDM。我们描述了具有挑战性的问题及其原因,以及多个STDM方向和方面的空白。具体来说,我们调查的挑战性问题,时空关系,跨学科,离散化和数据特性。此外,我们讨论了文献中的局限性和开放的研究问题,时空数据表示,建模和可视化,以及方法的全面性。我们解释了与分类,聚类,热点检测,关联和模式挖掘,离群值检测,可视化,可视化分析和计算机视觉任务的STDM任务相关的问题。我们还强调了与多种应用相关的STDM问题,包括犯罪和公共安全,交通和运输,地球和环境监测,流行病学,社交媒体和物联网。

英文摘要:

Spatiotemporal data mining (STDM) discovers useful patterns from the dynamic interplay between space and time. Several available surveys capture STDM advances and report a wealth of important progress in this field. However, STDM challenges and problems are not thoroughly discussed and presented in articles of their own. We attempt to fill this gap by providing a comprehensive literature survey on state-of-the-art advances in STDM. We describe the challenging issues and their causes and open gaps of multiple STDM directions and aspects. Specifically, we investigate the challenging issues in regards to spatiotemporal relationships, interdisciplinarity, discretisation, and data characteristics. Moreover, we discuss the limitations in the literature and open research problems related to spatiotemporal data representations, modelling and visualisation, and comprehensiveness of approaches. We explain issues related to STDM tasks of classification, clustering, hotspot detection, association and pattern mining, outlier detection, visualisation, visual analytics, and computer vision tasks. We also highlight STDM issues related to multiple applications including crime and public safety, traffic and transportation, earth and environment monitoring, epidemiology, social media, and Internet of Things.
