    The massive amount of tourists, citizens and traffic in big cities usually collapse busy areas causing transport inefficiency, unbalanced economic growth, crime, and nuisance among citizens and visitors. Therefore, the ...
  • High quality, scalable and parallel community detection for large real graphs 

    Prat Pérez, Arnau; Domínguez Sal, David; Larriba Pey, Josep (Association for Computing Machinery (ACM), 2014)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Community 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 ...
  • Massive query expansion by exploiting graph knowledge bases for image retrieval 

    Guisado Gámez, Joan; Domínguez Sal, David; Larriba Pey, Josep (Association for Computing Machinery (ACM), 2014)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Annotation-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 ...
  • Producer-consumer: the programming model for future many-core processors 

    Prat Pérez, Arnau; Domínguez Sal, David; Larriba Pey, Josep; Troncoso, Pedro (Springer, 2013)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    The 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 ...
  • Hybrid tables for speeding-up data accesses in hybrid database management systems 

    Guisado Gámez, Joan; Wolski, Antoni; Zuzarte, Calisto; Larriba Pey, Josep; Muntés Mulero, Víctor (2011)

    The 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, ...
  • Context-aware machine translation for software localization 

    Muntés Mulero, Víctor; Paladini Adell, Patricia; España Bonet, Cristina; Màrquez Villodre, Lluís (2012)
    Comunicació de congrés
    Accés obert
    Software localization requires translating short text strings appearing in user interfaces (UI) into several languages. These strings are usually unrelated to the other strings in the UI. Due to the lack of semantic ...
  • Memory-, bandwidth-, and power-aware multi-core for a graph database workload 

    Trancoso, Pedro; Martínez Bazán, Norbert; Larriba Pey, Josep (Springer, 2011)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    Processors 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 ...
  • Anonymizing data via polynomial regression 

    Nin Guerrero, Jordi; Pont Tuset, Jordi; Medrano Gracia, Pau; Larriba Pey, Josep; Muntés Mulero, Víctor (2007)
    Text en actes de congrés
    Accés obert
    The amount of confidential information accessible through the Internet is growing continuously. In this scenario, the improvement of anonymizing methods becomes crucial to avoid revealing sensible information of individuals. ...
  • Increasing polynomial regression complexity for data anonymization 

    Nin Guerrero, Jordi; Pont Tuset, Jordi; Medrano Gracia, Pau; Larriba Pey, Josep; Muntés Mulero, Víctor (IEEE Computer Society, 2007)
    Text en actes de congrés
    Accés obert
    Pervasive 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 ...
