Este Trabajo de Fin de Grado (TFG) tiene el objetivo de aportar un sistema de enseñanza innovador, un sistema de enseñanza mediante el cual se consiga involucrar a los alumnos en tareas y prácticas en las que se adquieran conocimientos a la vez que se siente un ambiente de juego, es decir, que se consiga aprender de forma divertida. Está destinado al sistema educativo de la Escuela Técnica Superior de Ingenieros Informáticos de la Universidad Politécnica de Madrid, en concreto a las asignaturas relacionadas con los Procesadores de Lenguajes. La aplicación desarrollada en este trabajo está destinada tanto a los profesores de las asignaturas de Procesadores de Lenguajes como a los alumnos que tengan alguna relación con esas asignaturas, consiguiendo mayor interacción y diversión a la hora de realizar la tareas y prácticas de las asignaturas. Para los dos tipos de usuarios descritos anteriormente, la aplicación está configurada para que puedan identificarse mediante sus credenciales, comprobándose si los datos introducidos son correctos, y así poder acceder al sistema. Dependiendo de qué tipo de usuario se identifique, tendrá unas opciones u otras dentro del sistema. Los profesores podrán dar de alta, ver, modificar o dar de baja las configuraciones para los analizadores de los lenguajes correspondientes a las diferentes asignaturas que están configurados previamente en el sistema. Además, los profesores pueden dar de alta, ver, modificar o dar de baja los fragmentos de código que formarán los ficheros correspondientes a las plantillas de pruebas del analizador léxico que se les ofrece a los alumnos para realizar comprobaciones de las prácticas. Mediante la aplicación podrán establecer diferentes características y propiedades de los fragmentos que incorporen al sistema. Por otra parte, los alumnos podrán realizar la configuración del lenguaje, definido por los profesores, para la parte del analizador léxico de las prácticas. Esta configuración será guardada para el grupo al que corresponde el alumno, pudiendo realizar modificaciones cualquier miembro del grupo. De esta manera, se podrán posteriormente establecer las relaciones necesarias entre los elementos del lenguaje según la configuración de los profesores y los elementos referentes a las prácticas de los alumnos.Además, los alumnos podrán realizar comprobaciones de la parte léxica de sus prácticas mediante los ficheros que se generan por el sistema en función de sus opciones de práctica y los fragmentos añadidos por los profesores. De esta manera, se informará a los alumnos del éxito de las pruebas o bien de los fallos ocasionados con sus resultados, bien por el formato del archivo subido como resultado de la prueba o bien por el contenido incorrecto de este mismo. Todas las funciones que ofrece esta aplicación son completamente on-line y tendrán una interfaz llamativa y divertida, además de caracterizarse por su facilidad de uso y su comodidad. En el trabajo realizado para este proyecto se cumplen tanto las Pautas de Accesibilidad para Contenidos Web (WCAG 2.0), así como las propiedades de un código HTML 5 y CSS 3 de manera correcta, para así conseguir que los usuarios utilicen una aplicación fácil, cómoda y atractiva.---ABSTRACT---This Final Year Project (TFG) aims to contribute the educational system of the School of Computer Engineering at the Polytechnic University of Madrid, especially in subjects related with Language Processors. This project is an interactive learning system whose goal is to learn in an amusing environment. To realize this target, the system involves students, using environments of games in tasks and practices. The application developed in this project is designed for both professors of the subjects of Language Processors and students who have some relation to these subjects. This perspective achieve more interaction and a funny environment during the subject‘s tasks. The application is configured in order to the users can be identified by their credentials, checking whether the identification data are correct to have access to the system. According on what type of user is identified, they will have different options within the system. Professors will be able to register, modify or delete settings for the scanner of languages for all the subjects preconfigured in the system. Additionally, professors can register, show, modify or remove the code of the templates from scanner tests that are offered to students for testing the practical exercises. The professors may provide also different characteristics and properties of fragments incorporated in the system. Moreover, students can make the configuration of languages, getting in the systems by the administrators, for the scanner module of their practical exercises. This configuration will be saved for the group of the student. This model can also be changed by any group member. The system permits also establish later the relationships between the elements of language fixes by professors and elements developed by the students. Students could check the lexical part of their practical exercises through files that are created according to their practical options and the fragments added by professors. Thus students will be informed of success or failure in the uploaded files format and in the content of them. All functions provide by this application are completely on-line and will have a striking and funny interface, also characterized by its ease of use and comfort.The work reaches both the Web Content Accessibility Guidelines (WCAG 2.0), and the properties of an HTML 5 and CSS 3 code correctly, in order to get the users to get an easy, convenient application and attractive.

Computational Swarms (enxames computacionais), consistindo da integração de sensores e atuadores inteligentes no nosso mundo conectado, possibilitam uma extensão da info-esfera no mundo físico. Nós chamamos esta info-esfera extendida, cíber-física, de Swarm. Este trabalho propõe uma visão de Swarm onde dispositivos computacionais cooperam dinâmica e oportunisticamente, gerando redes orgânicas e heterogêneas. A tese apresenta uma arquitetura computacional do Plano de Controle do Sistema Operacional do Swarm, que é uma camada de software distribuída embarcada em todos os dispositivos que fazem parte do Swarm, responsável por gerenciar recursos, definindo atores, como descrever e utilizar serviços e recursos (como divulgá-los e descobrí-los, como realizar transações, adaptações de conteúdos e cooperação multiagentes). O projeto da arquitetura foi iniciado com uma revisão da caracterização do conceito de Swarm, revisitando a definição de termos e estabelecendo uma terminologia para ser utilizada. Requisitos e desafios foram identificados e uma visão operacional foi proposta. Esta visão operacional foi exercitada com casos de uso e os elementos arquiteturais foram extraídos dela e organizados em uma arquitetura. A arquitetura foi testada com os casos de uso, gerando revisões do sistema. Cada um dos elementos arquiteturais requereram revisões do estado da arte. Uma prova de conceito do Plano de Controle foi implementada e uma demonstração foi proposta e implementada. A demonstração selecionada foi o Smart Jukebox, que exercita os aspectos distribuídos e a dinamicidade do sistema proposto. Este trabalho apresenta a visão do Swarm computacional e apresenta uma plataforma aplicável na prática. A evolução desta arquitetura pode ser a base de uma rede global, heterogênea e orgânica de redes de dispositivos computacionais alavancando a integração de sistemas cíber-físicos na núvem permitindo a cooperação de sistemas escaláveis e flexíveis, interoperando para alcançar objetivos comuns.

In this article, recent developments in the creation of web content, such as blogs and wikis, are surveyed with a focus on their role in technological and social innovation. The innovations associated with blogs and wikis are important in themselves, and the process of creative collaboration they represent is becoming central to technological progress in general. The internet and the world wide web, which have driven much of the economic growth of the past decade, were produced in this way. Standard assumptions about the competitive nature of innovation are undersupported in the new environment. If governments want to encourage the maximum amount of innovation in social production, they need to de-emphasize competition and emphasize creativity and cooperation.

Categorising visitors based on their interaction with a website is a key problem in Web content usage. The clickstreams generated by various users often follow distinct patterns, the knowledge of which may help in providing customised content. This paper proposes an approach to clustering weblog data, based on ART2 neural networks. Due to the characteristics of the ART2 neural network model, the proposed approach can be used for unsupervised and self-learning data mining, which makes it adaptable to dynamically changing websites.

Increased broadband penetration (BP) rates around the world have encouraged web designers to include more web content and additional functions on their web sites, thereby enhancing the richness and playfulness of the information. However, it is often very difficult for web surfers who are still using narrowband connections to access such web sites. Many university web sites target international audiences; therefore their download performance should be considered, as it may directly influence the user experience. This exploratory study examined 331 university hospitality and tourism department web sites in 37 countries. The empirical results showed that entry web pages of universities in Asia, with a medium BP rate (mid-BP), have the slowest download speeds, and those in Australia and New Zealand perform the best. The adoption rate of the Cascade Style Sheet (CSS) in Asia is relatively lower than that of other regions.

El artículo analiza la figura del prosumidor desde los estudios visuales a partir de la combinación de la teoría de los actos de habla y los nuevos medios. El objetivo es evaluar si la distinción entre productores y consumidores, estrategias y tácticas de Michel de Certeau continúa siendo operativa en las interfaces gráficas de la cultura global de la información de Scott Lash. Para ello distingue dos tipos de performatividad de los actos de habla: la performatividad top-down del software, y la bottom-up de los juegos del lenguaje y las formas de vida. Estos tipos se aplican al análisis del discurso de los eslóganes que aparecen en los sitios web de las iniciativas “open” y de economía colaborativa, ya que las primeras están dedicadas a la producción de bienes inmateriales y las segundas a la producción de bienes materiales. El desarrollo muestra cómo los dos tipos de performatividad transforman el análisis textual de los estudios literarios y cinematográficos en una metodología capaz de investigar acciones materiales, humanas y no humanas. Las conclusiones describen el surgimiento de nuevas convenciones narrativas de poder y control ajenas a la ficción que apuntan a una “DIY society”.

La nueva generación de la Web, la Web Semántica, plantea potenciales oportunidades para dotar de significado a los contenidos Web. Las ontologías constituyen una de las principales herramientas para especificar explícitamente los conceptos de un dominio concreto, sus propiedades y sus relaciones; de manera que la información se publique en formatos que sean inteligibles automáticamente por agentes máquinas que pueden localizar y gestionar de forma precisa la información. En este trabajo se presenta un marco de trabajo para una red de ontologías para representar conceptos, atributos, operaciones y restricciones, en relación a los ítems curriculares que se usan en procesos nacionales de categorización de docentes universitarios ecuatorianos. En una primera parte se muestra el contexto del dominio, trabajos relacionados, luego se describe el proceso seguido, la abstracción del modelo ontológico y finalmente se presenta una ontología. Es una ontología de dominio debido a que proporciona el significado de los conceptos y sus relaciones dentro del dominio de ítems curriculares producidos por docentes universitarios, que son requisitos de los proceso de categorización docente universitaria en Ecuador.

A Digital Scholarly Edition is a conceptually and structurally sophisticated entity. Throughout the centuries, diverse methodologies have been employed to reconstruct a text transmitted through one or multiple sources, resulting in various edition types. With the advent of digital technology in philology, these practices have undergone a significant transformation, compelling scholars to reconsider their approach in light of the web. In the digital age, philologists are expected to possess (too) advanced technical skills to prepare interactive and enriched editions, even though, in most cases, only mechanical or documentary editions are published online. The Śivadharma Database is a web Content Management System (CMS) designed to facilitate the preparation, publication, and updating of Digital Scholarly Editions. By providing scholars with a user-friendly CRUD web application to reconstruct and annotate a text, they can prepare their textus with additional components such as apparatus, notes, translations, citations, and parallels. It is possible by leveraging an annotation system based on HTML and graph data structure. This choice is made because the text entity is multidimensional and multifaceted, even if its sequential presentation constrains it. In particular, editions of South Asian texts of the Śivadharma corpus, the case study of this research, contain a series of phenomena that are difficult to manage formally, such as overlapping hierarchies. Hence, it becomes necessary to establish the data structure best suited to represent this complexity. In Śivadharma Database, the textus is an HTML file readily displayable. Textual fragments, annotated via an interface without requiring philologists to write code and saved in the backend, form the atomic unit of multiple relationships organised in a graph database. This approach enables the formal representation of complex and overlapping textual phenomena, allowing for good annotation expressiveness with minimal effort to learn the relevant technologies during the editing workflow.

This paper presents an ongoing project that implements a platform for creating personal learning environments controlled by students, integrating Web 2.0 applications and content management systems, enabling the safe use of content created in Web 2.0 applications, allowing its publication in the infrastructure controlled by the HEI. Using this platform, students can develop their personal learning environment (PLE) integrated with the Learning Management System (LMS) of the HEI, enabling the management of their learning and, simultaneously, creating their e-portfolio with digital content developed for Course Units (CU). All this can be maintained after the student completes his academic studies, since the platform will remain accessible to students even after they leave the HEI and lose access to its infrastructure. The platform will enable the safe use of content created in Web 2.0 applications, allowing its protected publication in the infrastructure controlled by HEI, thus contributing to the adaptation of the L&T paradigm to the Bologna process.

Introduction: Internet users are increasingly using the worldwide web to search for information relating to their health. This situation makes it necessary to create specialized tools capable of supporting users in their searches. Objective: To apply and compare strategies that were developed to investigate the use of the Portuguese version of Medical Subject Headings (MeSH) for constructing an automated classifier for Brazilian Portuguese-language web-based content within or outside of the field of healthcare, focusing on the lay public. Methods: 3658 Brazilian web pages were used to train the classifier and 606 Brazilian web pages were used to validate it. The strategies proposed were constructed using content-based vector methods for text classification, such that Naive Bayes was used for the task of classifying vector patterns with characteristics obtained through the proposed strategies. Results: A strategy named InDeCS was developed specifically to adapt MeSH for the problem that was put forward. This approach achieved better accuracy for this pattern classification task (0.94 sensitivity, specificity and area under the ROC curve). Conclusions: Because of the significant results achieved by InDeCS, this tool has been successfully applied to the Brazilian healthcare search portal known as Busca Saude. Furthermore, it could be shown that MeSH presents important results when used for the task of classifying web-based content focusing on the lay public. It was also possible to show from this study that MeSH was able to map out mutable non-deterministic characteristics of the web. (c) 2010 Elsevier Inc. All rights reserved.

Recent studies of mobile Web trends show a continuous explosion of mobile-friendly content. However, the increasing number and heterogeneity of mobile devices poses several challenges for Web programmers who want to automatically get the delivery context and adapt the content to mobile devices. In this process, the devices detection phase assumes an important role where an inaccurate detection could result in a poor mobile experience for the enduser. In this paper we compare the most promising approaches for mobile device detection. Based on this study, we present an architecture for a system to detect and deliver uniform m-Learning content to students in a Higher School. We focus mainly on the devices capabilities repository manageable and accessible through an API. We detail the structure of the capabilities XML Schema that formalizes the data within the devices capabilities XML repository and the REST Web Service API for selecting the correspondent devices capabilities data according to a specific request. Finally, we validate our approach by presenting the access and usage statistics of the mobile web interface of the proposed system such as hits and new visitors, mobile platforms, average time on site and rejection rate.
