  • GraCT: A Grammar based Compressedrepresentation of Trajectories 
    Nieves R., Brisaboa; Gómez-Brandón, Adrián; Navarro, Gonzalo; R.Paramá, José (2019)
    We present a compressed data structure to store free tra-jectories of moving objects (ships over the sea, for example) allowingspatio-temporal queries. Our method, GraCT, uses ak2-tree to store theabsolute positions of all ...
  • Compressed and Queryable Self-Indexes for RDF Archives 
    de Bernardo, Guillermo (2021)
    RDF compression and querying are consolidated topics in the Web of Data, with a plethora of solutions to efficiently store and query static datasets. However, as RDF data changes along time, it becomes necessary to keep ...
  • New Discovery Methodologies in GIS: Improving the Information Retrieval Process 
    R. Brisaboa, Nieves; R. Luaces, Miguel; Seco, Diego (2012)
    In the last decade the availability of on-line resources, and also the number of users accessing those resources, have grown exponentially. The information retrieval process, which aims at the improvement of the ...
  • Storing and Clustering Large Spatial Datasets Using Big Data Technologies 
    Cortiñas, Alejandro; R. Luaces, Miguel; Varela-Rodeiro, Tirso (LNCS, 2018)
    In this paper we present the architecture of a system to store, query and visualize on the web large datasets of geographic information. The architecture includes a component to simulate a large number of drivers ...
  • Bitvectors with runs and the successor/predecessor problem 
    Gómez-Brandón, Adrián; R. Brisaboa, Nieves (IEEE Computer Society, 2020)
    The successor and predecessor problem consists of obtaining the closest value in a set of integers, greater/smaller than a given value. This problem has interesting applications, like the intersection of inverted lists. ...
