An Architecture for Software Engineering Gamification
Óscar Pedreira, Félix García, Mario Piattini +2
Gamification has been applied in software engineering to improve quality and results by increasing people's motivation and engagement. A systematic mapping has identified research…
Optimization in Sanger Sequencing
Luisa Carpente, Ana Cerdeira-Pena, Silvia Lorenzo-Freire +1
The main objective of this paper is to solve the optimization problem that is associated with the classification of DNA samples in PCR plates for Sanger sequencing. To achieve this…
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…
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…
Efficient Representation of Multidimensional Data over Hierarchical Domains
Nieves R. Brisaboa, Ana Cerdeira-Pena, Narciso López-López +3
We consider the problem of representing multidimensional data where the domain of each dimension is organized hierarchically, and the queries require summary information at a diffe…
Ranked Document Retrieval in (Almost) No Space
Nieves R. Brisaboa, Ana Cerdeira-Pena, Gonzalo Navarro +1
Ranked document retrieval is a fundamental task in search engines. Such queries are solved with inverted indexes that require additional 45%-80% of the compressed text space, and t…
