“…Moving objects were usually abstracted as points (Ranu et al, 2015), single continuous polynomials (Ni and Ravishankar, 2007), or non-regulated sequences of roads in transportation networks (Sandu Popa et al, 2011). Then, these objects were indexed by the tree's derivatives, for example, B + -trees (Sandu Popa et al, 2011), R-trees (Yue et al, 2018), 3D R-trees (Xu et al, 2018), FN (fixed network) R-trees , PA-trees (Ni and Ravishankar, 2007), and grid trees (Yan et al, 2015). These tree-based indices could facilitate efficient queries on moving objects.…”

“…Moving object-oriented operators (i.e., range queries, nearestneighbor queries) were derived to support the analysis of moving objects' relationships. The first common operator is range queries, which specify a value of moving objects to fall within a lower and upper boundary Zhan et al, 2015;Xu et al, 2018;Yue et al, 2018), e.g., finding all the objects of a specific traveler between 7 am and 9 am. Filtering and refining are two important steps of range queries.…”

“…For example, the geo-textual objects in trajectories are associated with the location name, the point category (i.e., restaurants, museums) and etc. We unify the semantics 2 as the attributes of the trajectories into the form of a collection of textual keywords. The trajectories including the locations, timestamps, and descriptive attributers are called multi-attributes trajectories.…”
