Journal ArticleDOI
Dynamic monitoring of optimal locations in road network databases
TL;DR: A unified framework is proposed that addresses three variants of OL queries that find important applications in practice, and it is extended to efficiently monitor the OLs when locations for facilities and/or clients have been updated.

A Survey of RDF Stores & SPARQL Engines for Querying Knowledge Graphs
TL;DR: This survey paper draws together developments of the SPARQL query language for RDF, providing a comprehensive review of the techniques, engines and benchmarks for querying RDF knowledge graphs.
Journal ArticleDOI
Level-aware collective spatial keyword queries
TL;DR: It is proved the LCSK query is NP-hard, and the exact algorithm as well as approximate algorithm with provable approximation bound to this problem are devised.
Journal ArticleDOI
Spatio-temporal top- k term search over sliding window
TL;DR: This paper develops a novel and efficient mechanism to solve the problem of searching for the top-k terms by considering term frequency, spatial proximity, and term freshness, including a quad-tree based indexing structure, indexing update technique, and a best-first based searching algorithm.
Proceedings ArticleDOI
Graph-Flashback Network for Next Location Recommendation
TL;DR: A novel User-POI Knowledge Graph with strong representation ability is constructed, called Spatial-Temporal Knowledge Graph (STKG), which is used to learn a weighted POI graph, which could reflect the transition patterns among POIs and show the importance of its different neighbors for each POI.
