Semantrix: A Compressed Semantic Matrix
Nieves R. Brisaboa, Antonio Fariña, Gonzalo Navarro +1
We present a compact data structure to represent both the duration and length of homogeneous segments of trajectories from moving objects in a way that, as a data warehouse, it all…
Revisiting compact RDF stores based on k2-trees
Nieves R. Brisaboa, Ana Cerdeira-Pena, Guillermo de Bernardo +1
We present a new compact representation to efficiently store and query large RDF datasets in main memory. Our proposal, called BMatrix, is based on the k2-tree, a data structure de…
On the Reproducibility of Experiments of Indexing Repetitive Document Collections
Antonio Fariña, Miguel A. Martínez-Prieto, Francisco Claude +4
This work introduces a companion reproducible paper with the aim of allowing the exact replication of the methods, experiments, and results discussed in a previous work [5]. In tha…
New structures to solve aggregated queries for trips over public transportation networks
Nieves R. Brisaboa, Antonio Fariña, Daniil Galaktionov +2
Representing the trajectories of mobile objects is a hot topic from the widespread use of smartphones and other GPS devices. However, few works have focused on representing trips o…
Dv2v: A Dynamic Variable-to-Variable Compressor
Nieves R. Brisaboa, Antonio Fariña, Adrián Gómez-Brandón +2
We present Dv2v, a new dynamic (one-pass) variable-to-variable compressor. Variable-to-variable compression aims at using a modeler that gathers variable-length input symbols and a…
A Compact Representation for Trips over Networks built on self-indexes
Nieves R. Brisaboa, Antonio Fariña, Daniil Galaktionov +1
Representing the movements of objects (trips) over a network in a compact way while retaining the capability of exploiting such data effectively is an important challenge of real a…
