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…
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…
Improved Compressed String Dictionaries
Nieves R. Brisaboa, Ana Cerdeira-Pena, Guillermo de Bernardo +1
We introduce a new family of compressed data structures to efficiently store and query large string dictionaries in main memory. Our main technique is a combination of hierarchical…
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…
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…
