Space/time-efficient RDF stores based on circular suffix sorting
Nieves R. Brisaboa, Ana Cerdeira-Pena, Guillermo de Bernardo +2
In recent years, RDF has gained popularity as a format for the standardized publication and exchange of information in the Web of Data. In this paper we introduce RDFCSA, a data st…
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 dynamic succinct graph representations
Miguel E. Coimbra, Alexandre P. Francisco, Luís M. S. Russo +3
We address the problem of representing dynamic graphs using -trees. The -tree data structure is one of the succinct data structures proposed for representing static graph…
Faster Dynamic Compressed d-ary Relations
Diego Arroyuelo, Guillermo de Bernardo, Travis Gagie +1
The -tree is a successful compact representation of binary relations that exhibit sparseness and/or clustering properties. It can be extended to dimensions, where it is ca…
Extending General Compact Querieable Representations to GIS Applications
Nieves R. Brisaboa, Ana Cerdeira-Pena, Guillermo de Bernardo +2
The raster model is commonly used for the representation of images in many domains, and is especially useful in Geographic Information Systems (GIS) to store information about cont…
Towards a compact representation of temporal rasters
Ana Cerdeira-Pena, Guillermo de Bernardo, Antonio Fariña +2
Big research efforts have been devoted to efficiently manage spatio-temporal data. However, most works focused on vectorial data, and much less, on raster data. This work presents…
About BIRDS project (Bioinformatics and Information Retrieval Data Structures Analysis and Design)
Guillermo de Bernardo, Susana Ladra
BIRDS stands for "Bioinformatics and Information Retrieval Data Structures analysis and design" and is a 4-year project (2016--2019) that has received funding from the European Uni…
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…
Compressed Representation of Dynamic Binary Relations with Applications
Nieves R. Brisaboa, Ana Cerdeira-Pena, Guillermo de Bernardo +1
We introduce a dynamic data structure for the compact representation of binary relations . The data structure is a dynamic variant of the k-tr…
Aggregated 2D Range Queries on Clustered Points
Nieves R. Brisaboa, Guillermo De Bernardo, Roberto Konow +2
Efficient processing of aggregated range queries on two-dimensional grids is a common requirement in information retrieval and data mining systems, for example in Geographic Inform…
