  • Effective and scalable data discovery with NextiaJD 

    Flores Herrera, Javier de Jesús; Nadal Francesch, Sergi; Romero Moral, Óscar (OpenProceedings, 2021)
    Conference lecture
    Open Access
    We present NextiaJD, a data discovery system with high predictive performance and computational efficiency. NextiaJD aids data scientists in the discovery of datasets that can be crossed. To that end, it proposes a ranking ...
  • Towards scalable data discovery 

    Flores Herrera, Javier de Jesús; Nadal Francesch, Sergi; Romero Moral, Óscar (OpenProceedings, 2021)
    Conference lecture
    Open Access
    We study the problem of discovering joinable datasets at scale. We approach the problem from a learning perspective relying on profiles. These are succinct representations that capture the underlying characteristics of the ...
  • A data-driven approach to measure the usability of Web APIs 

    Koçi, Rediana; Franch Gutiérrez, Javier; Jovanovic, Petar; Abelló Gamazo, Alberto (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference report
    Open Access
    Application Programming Interfaces (APIs) are means of communication between applications, hence they can be seen as user interfaces, just with different kind of users, i.e., software or computers. However, the very first ...
  • Continual lifelong learning in natural language processing: a survey 

    Biesialska, Magdalena Marta; Biesialska, Katarzyna; Ruiz Costa-Jussà, Marta (Association for Computational Linguistics, 2020)
    Conference lecture
    Open Access
    Continual learning (CL) aims to enable information systems to learn from a continuous data stream across time. However, it is difficult for existing deep learning architectures to learn a new task without largely forgetting ...
  • Fireman Rescue: a serious game for fire fighting training 

    Ríos Jerez, Alejandro; Bonet Papell, Carles; López Morales, José Luis; Alavedra Cabello, Axel; París Gómez, Alejandro; Guillén Saltó, Marc (European Association for Computer Graphics (Eurographics), 2017)
    Conference report
    Open Access
    This paper introduces a Serious Game that will be used as a tool for training fire fighting students at the Public Security Institute of Catalonia. The game is played in a virtual environment free of real hazards and/or ...
  • Avatars rendering and its effect on perceived realism in virtual reality 

    Molina López, Elena; Ríos Jerez, Alejandro; Pelechano Gómez, Núria (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference report
    Open Access
    Immersive virtual environments have proven to be a plausible platform to be used by multiple disciplines to simulate different types of scenarios and situations at a low cost. When participants are immersed in a virtual ...
  • Estimación y priorización de requisitos no-funcionales para desarrollo de software: Estado del arte 

    Salamea Bravo, María José; González Palacio, Liliana; Oriol Hilari, Marc; Farré Tost, Carles (Instituto Antioqueño de Investigación, 2020)
    Conference report
    Open Access
    Los requisitos de calidad (también llamados requisitos no-funcionales) son aquellos que permiten asegurar la calidad del software. Incluyen aspectos muy diversos, como disponibilidad, seguridad, rendimiento, escalabilidad, ...
  • Easy authoring of image-supported short stories for 3D scanned cultural heritage 

    Comino Trinidad, Marc; Chica Calaf, Antonio; Andújar Gran, Carlos Antonio (European Association for Computer Graphics (Eurographics), 2020)
    Conference report
    Open Access
    Visual storytelling is a powerful tool for Cultural Heritage communication. However, traditional authoring tools either produce videos that cannot be fully integrated with 3D scanned models, or require 3D content creation ...
  • Feasible interpolation for polynomial calculus and sums-of-squares 

    Hakoniemi, Tuomas Antero (Schloss Dagstuhl - Leibniz-Zentrum für Informatik, 2020)
    Conference report
    Open Access
    We prove that both Polynomial Calculus and Sums-of-Squares proof systems admit a strong form of feasible interpolation property for sets of polynomial equality constraints. Precisely, given two sets P(x, z) and Q(y, z) of ...
  • Integrating the Science Opportunity Analyzer with a reusable opportunity search framework 

    Llopis, Marcel; Franch Gutiérrez, Javier; Soria Guerrero, Manel (American Institute of Aeronautics and Astronautics (AIAA), 2020)
    Conference report
    Restricted access - publisher's policy
    In our interactions with the Science Opportunity Analyzer (SOA) software, we recognized how its ability to search for geometric events in space is a need for robotic space missions in general. To satisfy this need, we ...
  • Extracting annotations from textual descriptions of processes 

    Quishpi Betún, Luis Hernán; Carmona Vargas, Josep; Padró, Lluís (Springer, 2020)
    Conference report
    Open Access
    Organizations often have textual descriptions as a way to document their main processes. These descriptions are primarily used by the company’s personnel to understand the processes, specially for those ones that cannot ...
  • Business process variant analysis based on mutual fingerprints of event logs 

    Taymouri, Farbod; La Rosa, Marcello; Carmona Vargas, Josep (Springer, 2020)
    Conference report
    Open Access
    Comparing business process variants using event logs is a common use case in process mining. Existing techniques for process variant analysis detect statistically-significant differences between variants at the level of ...
