人与虚拟空间的时空交互过程形成了虚拟轨迹。虚拟轨迹为研究人与虚拟/物理空间的关系提供了新的视角。公共地图服务平台作为一种应用最为广泛的虚拟空间,其空间基准与物理空间一致,该空间下的虚拟轨迹蕴含了人的兴趣偏好,能够预示物理空间中潜在的空间交互倾向,是当前主流研究对象。然而,虚拟轨迹的概念特征和研究框架尚未确立,阻碍了虚拟轨迹研究的发展。本文定义了该空间下虚拟轨迹的基本概念,分析了虚拟轨迹的多尺度、不确定性特征,从表达建模和分析挖掘角度提出了虚拟轨迹研究框架。表达建模方法包括时序降噪、空间降维、空间分割的时空表达,基于目标点识别与筛选的路径还原,以及结合空间共现和语义匹配的语义还原。分析挖掘体系梳理了领域分类、主题聚类、动态演化等个体模式研究方向,以及时空分布规律、时空分布预测、虚实关联模式等群体模式研究现状。在理论基础、技术体系、空间语义、开源数据、应用场景方面探讨未来的研究方向,本文所构建的虚拟轨迹研究框架也将成为理解人在虚拟空间中空间活动规律的新范式。
