      Conference report
      Open Access
      Assistive Technologies (AT) are an application area where several Artificial Intelligence techniques and tools have been successfully applied to support elder or impeded people on their daily activities. However, approaches ...
    • Social network data analysis for event detection 

      Garcia Gasulla, Dario; Álvarez Napagao, Sergio; Tejeda Gómez, José Arturo; Oliva Felipe, Luis Javier; Gómez Sebastià, Ignasi; Béjar Alonso, Javier; Vázquez Salceda, Javier (IOS Press, 2014)
      Conference lecture
      Open Access
      Cities concentrate enough Social Network (SN) activity to empower rich models. We present an approach to event discovery based on the information provided by three SN, minimizing the data properties used to maximize the ...
    • Socially-aware emergent narrative 

      Álvarez Napagao, Sergio; Gómez Sebastià, Ignasi; Panagiotidi, Sofia; Tejeda Gómez, José Arturo; Oliva Felipe, Luis Javier; Vázquez Salceda, Javier (2012)
      Conference report

      Assistive technologies are applied to support people in their daily life. Most approaches focus solely on the direct interaction between users – in our case, disabled patients - and the assistive tool, but Artificial ...
    • Towards a framework for the analysis of regulative norm performance in complex networks 

      Oliva Felipe, Luis Javier; Álvarez Napagao, Sergio; Vázquez Salceda, Javier (2012)
      Conference lecture
      Open Access
      Systemic analysis of dynamics in complex networks has allured interest from different fields. Norms are a mechanism that can be useful to govern or guide the behavior of agents in such scenarios. Such effects of norms can ...
    • Towards a goal-oriented agent-based simulation framework for high-performance computing 

      Gnatyshak, Dmitry; Oliva Felipe, Luis Javier; Álvarez Napagao, Sergio; Padget, Julián; Vázquez Salceda, Javier; Garcia Gasulla, Dario; Cortés García, Claudio Ulises (IOS Press, 2019)
      Conference lecture
      Open Access
      Currently, agent-based simulation frameworks force the user to choose between simulations involving a large number of agents (at the expense of limited agent reasoning capability) or simulations including agents with ...
