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…
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…
Compact Representations of Event Sequences
Nieves R. Brisaboa, Guillermo de Bernardo, Gonzalo Navarro +2
We introduce a new technique for the efficient management of large sequences of multidimensional data, which takes advantage of regularities that arise in real-world datasets and s…
