Efficient Computation of Top-k Frequent Terms over Spatio-temporal Ranges
Summary: Top-k Frequent Spatio-Temporal Terms (kFST) queries over geotagged posts return exact keywords and frequencies within a spatiotemporal region. An R-tree augmented with top-k sorted term lists (STLs) balances index size and query speed, with theory-guided STL length and extensive real-data experiments against baselines on disk-resident data.
