    • Cold. Revisiting hub labels on the database for large-scale graphs 

      Efentakis, Alexandros; Efstathiades, Christodoulos; Pfoser, Dieter (2015-01-01)
      Shortest-path computation is a well-studied problem in algorithmic theory. An aspect that has only recently attracted attention is the use of databases in combination with graph algorithms to compute distance queries on ...
    • Efficient processing of relevant nearest-neighbor queries 

      Efstathiades, Christodoulos; Efentakis, Alexandros; Pfoser, Dieter (2016-09-01)
      Novel Web technologies and resulting applications have led to a participatory data ecosystem that, when utilized properly, will lead to more rewarding services. In this work, we investigate the case of Location-Based ...
    • Hub Labels on the database for large-scale graphs with the COLD framework 

      Efentakis, Alexandros; Efstathiades, Christodoulos; Pfoser, Dieter (2017-10-01)
      Shortest-path computation on graphs is one of the most well-studied problems in algorithmic theory. An aspect that has only recently attracted attention is the use of databases in combination with graph algorithms, so-called ...
