k nearest neighbor pattern match queries over spatio-temporal label trajectories

Spatio-temporal label trajectories extended traditional spatio-temporal trajectories with semantic labels.k nearest neighbor pattern match was proposed to return the k nearest trajectories that fulfilled the temporal pattern condition.The Label R-Tree (LR-Tree for short) was proposed,which appending...
