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…
