  2. Semantic Trajectory • Composes 2 patterns developed at GeoVoCampSB2012 • Point Of Interest (POI) • Motion/Path • Emerging term in the literature • Capture the semantics of motion as well as those of the geographic points • ZhixianYan. Towards Semantic Trajectory Data Analysis: A Conceptual and Computational Approach. VLDB 2009.
