  • Optimality of syntactic dependency distances 

    Ferrer Cancho, Ramon; Gómez Rodríguez, Carlos; Esteban Ángeles, Juan Luis; Alemany Puig, Lluís (American Institute of Physics (AIP), 2022-01-01)
    Article
    Open Access
    It is often stated that human languages, as other biological systems, are shaped by cost-cutting pressures but, to what extent? Attempts to quantify the degree of optimality of languages by means of an optimality score ...
  • Leveraging contextual embeddings and self-attention neural networks with bi-attention for sentiment analysis 

    Biesialska, Magdalena Marta; Biesialska, Katarzyna; Rybinski, Henryk (Springer Nature, 2021-12-01)
    Article
    Open Access
    People express their opinions and views in different and often ambiguous ways, hence the meaning of their words is often not explicitly stated and frequently depends on the context. Therefore, it is difficult for machines ...
  • Non-technical losses detection in energy consumption focusing on energy recovery and explainability 

    Coma Puig, Bernat; Carmona Vargas, Josep (2021-09-29)
    Article
    Open Access
    Non-technical losses (NTL) is a problem that many utility companies try to solve, often using black-box supervised classifcation algorithms. In general, this approach achieves good results. However, in practice, NTL detection ...
  • The impact of animations in the perception of a simulated crowd 

    Molina López, Elena; Ríos Jerez, Alejandro; Pelechano Gómez, Núria (Springer, 2021)
    Part of book or chapter of book
    Open Access
    Simulating virtual crowds is an important challenge in many areas such as games and virtual reality applications. A lot of effort has been dedicated to improving pathfinding, collision avoidance, or decision making, to ...
  • Minimum projective linearizations of trees in linear time 

    Alemany Puig, Lluís; Esteban Ángeles, Juan Luis; Ferrer Cancho, Ramon (2022-03)
    Article
    Open Access
    The Minimum Linear Arrangement problem (MLA) consists of finding a mapping π from vertices of a graph to distinct integers that minimizes {u,v}∈E |π(u) − π(v)|. In that setting, vertices are often assumed to lie on a ...
  • Visual analysis of large-scale protein-ligand interaction data 

    Schatz, Karsten; Franco Moreno, Juan José; Schäfer, Marco; Rose, Alexander S.; Ferrario, Valerio; Pleiss, Jürgen; Vázquez Alcocer, Pere Pau; Ertl, Thomas; Krone, Michael (2021-09)
    Article
    Open Access
    When studying protein-ligand interactions, many different factors can influence the behaviour of the protein as well as the ligands. Molecular visualisation tools typically concentrate on the movement of single ligand ...
  • Unleashing textual descriptions of business processes 

    Sànchez-Ferreres, Josep; Burattin, Andrea; Carmona Vargas, Josep; Montali, Marco; Padró, Lluís; Quishpi Betún, Luis Hernán (2021-12)
    Article
    Open Access
    Textual descriptions of processes are ubiquitous in organizations, so that documentation of the important processes can be accessible to anyone involved. Unfortunately, the value of this rich data source is hampered by the ...
  • Semantics for connectivity management in IoT sensing 

    Vila Gómez, Marc; Sancho Samsó, María Ribera; Teniente López, Ernest; Vilajosana Guillén, Xavier (Springer Nature, 2021)
    Conference report
    Open Access
    There are a large number of Internet of Things (IoT) devices that transmit information over the Internet, each with a different data format to denote the same semantic concept. This often leads to data incompatibilities ...
  • Improving the extraction of process annotations from text with inter-sentence analysis 

    Quishpi Betún, Luis Hernán; Carmona Vargas, Josep; Padró, Lluís (Springer, 2020)
    Conference report
    Open Access
    The automatic extraction of formal process information from textual descriptions of processes is a challenging problem, but worth exploring, since it enables organizations to align complementary information that talks about ...
  • XYZ Monitor: IoT monitoring of infrastructures using microservices 

    Vila Gómez, Marc; Sancho Samsó, María Ribera; Teniente López, Ernest (Springer, 2020)
    Conference report
    Open Access
    One of the main features of the Internet of Things (IoT) is the ability to collect data from everywhere, convert this data into knowledge, and then use this knowledge to monitor about an undesirable situation. Monitoring ...
  • Cumulated burden of Covid-19 in Spain from a Bayesian perspective 

    Moriña, David; Fernandez Fontelo, Amanda; Cabaña Nigro, Ana Alejandra; Arratia Quesada, Argimiro Alejandro; Ávalos Villaseñor, Gustavo Eduardo; Puig, Pedro (2021-12)
    Article
    Open Access
    Background The main goal of this work is to estimate the actual number of cases of Covid-19 in Spain in the period 01-31-2020/06-01-2020 by Autonomous Communities. Based on these estimates, this work allows us to accurately ...
  • Sentiment analysis of financial news: mechanics and statistics 

    Arratia Quesada, Argimiro Alejandro; Ávalos Villaseñor, Gustavo Eduardo; Cabaña Nigro, Ana Alejandra; Duarte López, Ariel; Renedo Mirambell, Martí (Springer, 2021-06-11)
    Part of book or chapter of book
    Open Access
    This chapter describes the basic mechanics for building a forecasting model that uses as input sentiment indicators derived from textual data. In addition, as we focus our target of predictions on financial time series, ...
