DEX: High-performance exploration on large graphs for information retrieval
(2007)
Text en actes de congrés
Accés restringit per política de l'editorialLink and graph analysis tools are important devices to boost the richness of information retrieval systems. Internet and the existing social networking portals are just a couple of situations where the use of these tools ... -
Efficient graph management based on bitmap indices
(Association for Computing Machinery (ACM), 2012)
Text en actes de congrés
Accés restringit per política de l'editorialThe increasing amount of graph like data from social networks, science and the web has grown an interest in analyzing the relationships between different entities. New specialized solutions in the form of graph databases, ... -
Fetching instruction streams
(Institute of Electrical and Electronics Engineers (IEEE), 2002)
Text en actes de congrés
Accés obertFetch performance is a very important factor because it effectively limits the overall processor performance. However there is little performance advantage in increasing front-end performance beyond what the back-end can ... -
High quality, scalable and parallel community detection for large real graphs
(Association for Computing Machinery (ACM), 2014)
Text en actes de congrés
Accés restringit per política de l'editorialCommunity detection has arisen as one of the most relevant topics in the field of graph mining, principally for its applications in domains such as social or biological networks analysis. Different community detection ... -
Hybrid in-memory and on-disk tables for speeding-up table accesses
(Springer, 2010)
Text en actes de congrés
Accés obertMain memory database management systems have become essential for response-time-bounded applications, such as those in telecommunications systems or Internet, where users frequently access a table in order to get information ... -

Improving microaggregation for complex record anonymization
(Springer Verlag, 2008)
Text en actes de congrés
Accés restringit per política de l'editorialMicroaggregation is one of the most commonly employed microdata protection methods. This method builds clusters of at least k original records and replaces the records in each cluster with the centroid of the cluster. ... -
Increasing polynomial regression complexity for data anonymization
(IEEE Computer Society, 2007)
Text en actes de congrés
Accés obertPervasive computing and the increasing networking needs usually demand from publishing data without revealing sensible information. Among several data protection methods proposed in the literature, those based on linear ... -
Instruction fetch architectures and code layout optimizations
(2001-11)
Article
Accés obertThe design of higher performance processors has been following two major trends: increasing the pipeline depth to allow faster clock rates, and widening the pipeline to allow parallel execution of more instructions. Designing ... -
Intensive crossovers: Improving quality in a genetic query optimizer
(International Centre for Numerical Methods in Engineering (CIMNE), 2006)
Text en actes de congrés
Accés obertDatabase schemas and user queries are continuously growing with the need for storing and accessing large amounts of structured information. Among the several proposals to deal with Large Join Query Problem, genetic optimizers ... -
Introduction to graph databases
(2014-09-08)
Capítol de llibre
Accés restringit per política de l'editorialThe use of graphs in analytic environments is getting more and more widespread, with applications in many different environments like social network analysis, fraud detection, industrial management, knowledge analysis, ... -
Massive query expansion by exploiting graph knowledge bases for image retrieval
(Association for Computing Machinery (ACM), 2014)
Text en actes de congrés
Accés restringit per política de l'editorialAnnotation-based techniques for image retrieval suffer from sparse and short image textual descriptions. Moreover, users are often not able to describe their needs with the most appropriate keywords. This situation is a ... -
Memory-, bandwidth-, and power-aware multi-core for a graph database workload
(Springer, 2011)
Comunicació de congrés
Accés restringit per política de l'editorialProcessors have evolved to the now de-facto standard multicore architecture. The continuous advances in technology allow for increased component density, thus resulting in a larger number of cores on the chip. This, in ... -
Multi-vehicle route planning for efficient urban freight transport
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Text en actes de congrés
Accés obertThe urban parking spaces for loading/unloading are typically over-occupied, which shifts delivery operations to traffic lanes and pavements, increases traffic, generates noise, and causes pollution. We present a data ... -
On the use of semantic blocking techniques for data cleansing and integration
(IEEE Computer Society, 2007)
Text en actes de congrés
Accés obertRecord Linkage (RL) is an important component of data cleansing and integration. For years, many efforts have focused on improving the performance of the RL process, either by reducing the number of record comparisons ... -
Optimization of instruction fetch for decision support workloads
(Institute of Electrical and Electronics Engineers (IEEE), 1999)
Text en actes de congrés
Accés obertInstruction fetch bandwidth is feared to be a major limiting factor to the performance of future wide-issue aggressive superscalars. In this paper, we focus on database applications running decision support workloads. We ... -
Parameter determination of ONN (Ordered Neural Networks)
(2007)
Report de recerca
Accés obertThe need for data privacy motivates the development of new methods that allow to protect data minimizing the disclosure risk without losing information. In this paper, we propose a new protection method for numerical data ... -
Producer-consumer: the programming model for future many-core processors
(Springer, 2013)
Text en actes de congrés
Accés restringit per política de l'editorialThe massive addition of cores on a chip is adding more pressure to the accesses to main memory. In order to avoid this bottleneck, we propose the use of a simple producer-consumer model, which allows for the temporary ... -
