Optimality of syntactic dependency distances
(American Institute of Physics (AIP), 2022-01-01)
Article
Open AccessIt 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
(Springer Nature, 2021-12-01)
Article
Open AccessPeople 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
(2021-09-29)
Article
Open AccessNon-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
(Springer, 2021)
Part of book or chapter of book
Open AccessSimulating 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
(2022-03)
Article
Open AccessThe 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
(2021-09)
Article
Open AccessWhen 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
(2021-12)
Article
Open AccessTextual 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
(Springer Nature, 2021)
Conference report
Open AccessThere 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
(Springer, 2020)
Conference report
Open AccessThe 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
(Springer, 2020)
Conference report
Open AccessOne 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
(2021-12)
Article
Open AccessBackground 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
(Springer, 2021-06-11)
Part of book or chapter of book
Open AccessThis 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, ...
