基于空间语义轨迹的GPS航迹行为特征检测研究

摘要

针对 GPS 航海定位系统轨迹检测缺乏语义的特点，提出一种基于空间语义轨迹的 GPS 航迹行为特征检测方法。该方法使用 OWL 形式描述 GPS 航迹行为特征，构建本体行为特征库以及提取航迹行为之间的数据依赖关系，在此基础上运用启发式的搜索算法生成关于 Stop 序列集的语义轨迹。然后，通过基于语义描述 ALC-Tableau 的逻辑推理，将 Stop 实例集与行为特征库相匹配。最后，通过实验分析验证该方法的有效性。%The paper proposes a spatial-semantic trajectory based GPS tracking behavior signature detection method to remedy the lacking of semantics of GPS navigation positioning system trajectory detection.The proposed method describes GPS tracking behavior characteristics in OWL format,builds ontology behavior characteristics library and extracts data dependencies among tracking behaviors.On the above foundation it generates the semantic trajectory of Stop sequence set by heuristic search algorithm.Then it matches the Stop sequence set with behavior characteristic library by semantics-based description of ALC-Tableau reasoning.Finally a experiment analysis validates the effectiveness of the proposed method.
