  • Indexing objects moving on fixed networks  
  • by Elias Frentzos — 2003 — In Proc. of the 8th Intl. Symp. on Spatial and Temporal Databases (SSTD
  • …Abstract. The development of a spatiotemporal access method suitable for objects moving on fixed networks is a very attractive challenge due to the great number of real-world spatiotemporal database applications and fleet management systems dealing with this type of objects. In this work, a new inde…

  • THEODORIDIS Y.: Towards a Taxonomy of Location Based Services  
  • by Kostas Gratsias, Elias Frentzos, Vasilis Delis, Yannis Theodoridis — 2005 — W2GIS 2005, Lecture Notes in Computer Science
  • …Abstract. Location-based services (LBS) constitute an emerging application domain involving spatio-temporal databases. In this paper, i) we propose a classification of LBS, depending on whether the user (query object) and the data objects are moving or not and ii) we provide algorithms for the effic…

  • 1 Index-based Most Similar Trajectory Search  
  • by Elias Frentzos, Kostas Gratsias, Yannis Theodoridis, Elias Frentzos, Kostas Gratsias, Yannis Theodoridis — 2006
  • …The problem of trajectory similarity in moving object databases is a relatively new topic in the spatial and spatiotemporal database literature. Existing work focuses on the spatial notion of similarity ignoring the temporal dimension of trajectories and disregarding the presence of a general-purpos…

  • Nearest neighbor search on moving object trajectories  
  • by Elias Frentzos, Kostas Gratsias, Nikos Pelekis, Yannis Theodoridis — 2005 — In Proc. of the 9th Intl. Symp. on Spatial and Temporal Databases (SSTD
  • …Abstract. With the increasing number of Mobile Location Services (MLS), the need for effective k-NN query processing over historical trajectory data has become the vehicle for data analysis, thus improving existing or even proposing new services. In this paper, we investigate mechanisms to perform N…
