Defining classifier regions for WSD ensembles using word space features
2006
Based on recent evaluation of word sense disambiguation (WSD) systems [10], disambiguation methods have reached a standstill. In [10] we showed that it is possible to predict the best system for target word using word features and that using this 'optimal ensembling method' more accurate WSD ensembles can be built (3-5% over Senseval state of the art systems with the same amount of possible potential remaining). In the interest of developing if more accurate ensembles, w e here define the strong regions for three popular and effective classifiers used for WSD task (Naive Bayes – NB, Support Vector Machine – SVM, Decision Rules – D) using word features (word grain, amount of positive and neg…

Hierarchy and centrality are two popular notions used to characterize the importance of entities in complex systems. Indeed, many complex systems exhibit a natural hierarchical structure, and centrality is a fundamental characteristic allowing to identify key constituents. Several measures based on various aspects of network topology have been proposed in order to quantify these concepts. While numerous studies have investigated whether centrality measures convey redundant information, how centrality and hierarchy measures are related is still an open issue. In this paper, we investigate the association between centrality and hierarchy using several correlation and similarity evaluation mea…
Building an Optimal WSD Ensemble Using Per-Word Selection of Best System
2006
In Senseval workshops for evaluating WSD systems [1,4,9], no one system or system type (classifier algorithm, type of system ensemble, extracted feature set, lexical knowledge source etc.) has been discovered that resolves all ambiguous words into their senses in a superior way. This paper presents a novel method for selecting the best system for target word based on readily available word features (number of senses, average amount of training per sense, dominant sense ratio). Applied to Senseval-3 and Senseval-2 English lexical sample state-of-art systems, a net gain of approximately 2.5 – 5.0% (respectively) in average precision per word over the best base system is achieved. The method c…
Impact of COVID-19 on the self-reported physical activity of people with complete thoracic spinal cord injury full-time manual wheelchair users
2021
Coronavirus SARS-CoV-2; COVID-19; 2019-nCoV; Activitat física; Lesió medul·lar Coronavirus SARS-CoV-2; COVID-19; 2019-nCoV; Actividad física; Lesión de la médula espinal Coronavirus SARS-CoV-2; COVID-19; 2019-nCoV; Physical activity; Spinal cord injury Context The emergence of COVID-19 caused a new public health crisis, leading to major changes in daily life routines, often including physical activity (PA) levels. The main goal of this study was to analyze the differences in self-reported physical activity of people with complete spinal cord injuries between the time prior to the COVID-19 lockdown and the lockdown period itself. Methods A sample of 20 participants with complete thoracic spi…
Methodological Approach for Identifying Mechanisms in ICT4D: A Critical Realism Perspective
2017
Part 4: Social Mechanisms of ICT-Enabled Development; International audience; The ontological questions ‘What is ICT?’ and ‘What is development?’ are described and documented in literature. Similarly, methodological approaches for understanding how ICT leads to development or for measuring the impact of ICT are described. However, explaining ‘why’ ICT works or not in the contexts of developing countries needs further investigation. We propose a critical realism based methodological approach for answering the above mentioned ‘why’-question. The core of a critical realism based approach is to identify the underlying mechanism(s) that may explain a phenomenon of why ICT leads to development. W…
Towards a Coming Together of Transhumanism and Play
2018
We note a trend on utilizing interactive technology to extend human capacities through bodily cyborg-like integrations such as artificial limbs and implantables. This trend is often captured by the term "transhumanism", referring to the use of technology to extend human capacities. We find that many transhuman discussions appear to focus on instrumental benefits (i.e. exploiting opportunities to be more productive). We extend this by proposing engagement with transhumanism also from a perspective of "play". We reflect on our own and other's work to articulate three strategies for game designers on how they can engage with transhumanism when aiming to facilitate playful experiences. Ultimate…

La Lucha Cinematográfica entre Oriente y Occidente. Studio Ghibli versus Disney.
2020
El cine de animacion es uno de los elementos, de la cultura visual, con un impacto en la confeccion de la identidad y personalidad de quienes pertenecen a la infancia; transmitiendo y asentando en este grupo una serie de posicionamientos e ideologias que varian dependiendo del contexto geografico del que las peliculas emergen. Por un lado, se cuenta con Disney en el territorio occidental y, por otro lado, con Studio Ghibli en el sector oriental, como estudios cinematograficos de animacion punteros en la industria. Ambas se centran en los mismos temas, pero difieren en la manera de abordarlos. Ademas, se seleccionan para esta investigacion por el gran alcance mediatico que ambas suponen. Por…
Transitando la Ruptura Familiar: Una Aproximación Hacia la Coordinación de Parentalidad.
2020
El modelo tradicional de familia ha sufrido cambios durante los ultimos tiempos, existiendo un incremento de separaciones y divorcios, a la vez que un aumento en la cifra de los procesos de ruptura judicializados. En torno a dicha realidad socio-familiar, es importante garantizar el derecho fundamental de los menores a relacionarse adecuadamente tanto con su padre como con su madre manteniendo todos sus vinculos. Ello se debe a que el problema surge no por el hecho de que los progenitores decidan poner fin a su vida en comun, sino cuando se hace participes a sus hijos de los conflictos que ha generado la separacion o divorcio. Dichos procesos de ruptura familiar con alta conflictividad supo…
Cell state prediction through distributed estimation of transmit power
2019
Determining the state of each cell, for instance, cell outages, in a densely deployed cellular network is a difficult problem. Several prior studies have used minimization of drive test (MDT) reports to detect cell outages. In this paper, we propose a two step process. First, using the MDT reports, we estimate the serving base station’s transmit power for each user. Second, we learn summary statistics of estimated transmit power for various networks states and use these to classify the network state on test data. Our approach is able to achieve an accuracy of 96% on an NS-3 simulation dataset. Decision tree, random forest and SVM classifiers were able to achieve a classification accuracy of…
