  • Generalized Vicinity Query Algorithm in Road Network Distance 
    Ohsawa, Yutaka; Htoo, Htoo; Sein, Myint Myint (Fourteenth International Conference On Computer Applications (ICCA 2016), 2016-02-25)
    Vicinity queries include set k nearest neighbor (SetkNN) query, ordered k nearest neighbor (OrderkNN) query, bi-chromatic reverse nearest neighbor (BRkNN) query and distance range query. In existing approaches, each ...
  • Light Materialized Path View for Location Based Services 
    Ohsawa, Yutaka; Hlaing, Aye Thida (Twelfth International Conference On Computer Application (ICCA 2014), 2014-02-17)
    This paper proposes a shortest path search algorithm based on materialized-path-view constructed only on partitioned subgraphs, and its three variations referring different levels of distance materialization. A road ...
  • Reverse kNN Query Algorithm on Road Network Distance 
    Win, Tin Nilar; Htoo, Htoo; Ohsawa, Yutaka (Thirteenth International Conferences on Computer Applications(ICCA 2015), 2015-02-05)
    This paper proposed a reverse k nearest neighbor (RkNN) query algorithm in road network distance by using the simple materialization path view (SMPV) data structure.When a set of interest objects P and a query point q ...
  • Skyline Trip Planning Queries 
    Htoo, Htoo; Ohsawa, Yutaka (Sixteenth International Conferences on Computer Applications(ICCA 2018), 2018-02-22)
    Given a current point and a final destination, and visiting data point categories on a trip, a sequenced route query finds the shortest route which meets the specific query condition. When this query is used in real ...
