A Perspective on Computer Assisted Assessment Techniques for Short Free-Text Answers

Computer Assisted Assessment (CAA) has been existing for several years now. While some forms of CAA do not require sophisticated text understanding (e.g., multiple choice questions), there are also student answers that consist of free text and require analysis of text in the answer. Research towards the latter till date has concentrated on two main sub-tasks: (i) grading of essays, which is done mainly by checking the style, correctness of grammar, and coherence of the essay and (ii) assessment of short free-text answers. In this paper, we present a structured view of relevant research in automated assessment techniques for short free-text answers. We review papers spanning the last 15 years of research with emphasis on recent papers. Our main objectives are two folds. First we present the survey in a structured way by segregating information on dataset, problem formulation, techniques, and evaluation measures. Second we present a discussion on some of the potential future directions in this domain which we hope would be helpful for researchers.

Rehabilitació i control d'un manipulador industrial

El grup de visió per computadora de la Universitat de Girona, disposava d’un manipulador lineal com a sistema de posicionament, per poder inspeccionar mitjançant visió artificial, la superfície de diverses peces. El control es realitzava a partir d’un PLC, controlant la posició de la plataforma de posicionament a partir d’un servomotor, un servocontrolador i una targeta d’entrada i sortida de polsos. Es pretén la recuperació d’aquest sistema de posicionament lineal a partir de la recopilació de la informació inicial. El nou ús serà enfocat al posicionament i a la classificació de diversos elements. D’aquesta forma es podrà estudiar el funcionament d’un servomotor governat per un servodriver i una targeta d’entrada i sortida de polsos i s’utilitzarà com a element didàctic per a la universitat. Es complementarà la documentació disponible i s’elaborarà informació tècnica

Paral·lelització especulativa de programes sobre un clúster

Estudi sobre la millora de rendiment (en temps d’execució) a l'algorisme de gràfics Fast Multipath Radiosity Using Hierarchical Subscenes gràcies a l’execució paral•lela especulada que ens permet obtenir el motor d'especulació per a clústers desenvolupat en el grup de recerca BCDS de la Universitat de Girona

Entorn de simulació per a xarxes òptiques de transport

Aquest projecte final de carrera pretén investigar i experimentar una nova línia de desenvolupament d’algorismes dinàmics. A partir de l’algorisme AntNet-QoS [2] s’ incorporen noves mesures a l’algorisme (mesura de l’amplada de banda disponible i jitter), les quals combinant amb la mesura de retard ja feta servir, permet adaptar-se millor a les condicions actuals del trànsit en la xarxa i als requeriments específics de qualitat (QoS) per part del trànsit

Enhancing fault management performance of two-step QoS routing algorithms in GMPLS networks

In this paper a novel methodology aimed at minimizing the probability of network failure and the failure impact (in terms of QoS degradation) while optimizing the resource consumption is introduced. A detailed study of MPLS recovery techniques and their GMPLS extensions are also presented. In this scenario, some features for reducing the failure impact and offering minimum failure probabilities at the same time are also analyzed. Novel two-step routing algorithms using this methodology are proposed. Results show that these methods offer high protection levels with optimal resource consumption

Enhancing MPLS QoS routing algorithms by using the network protection degree paradigm

IP based networks still do not have the required degree of reliability required by new multimedia services, achieving such reliability will be crucial in the success or failure of the new Internet generation. Most of existing schemes for QoS routing do not take into consideration parameters concerning the quality of the protection, such as packet loss or restoration time. In this paper, we define a new paradigm to develop new protection strategies for building reliable MPLS networks, based on what we have called the network protection degree (NPD). This NPD consists of an a priori evaluation, the failure sensibility degree (FSD), which provides the failure probability and an a posteriori evaluation, the failure impact degree (FID), to determine the impact on the network in case of failure. Having mathematical formulated these components, we point out the most relevant components. Experimental results demonstrate the benefits of the utilization of the NPD, when used to enhance some current QoS routing algorithms to offer a certain degree of protection
