Federico Castanedo, Juan Gomez-Romero, Miguel A. Patricio, Jesus García, Jose M. Molina. “Distributed Data and Information Fusion in Visual Sensor Networks”. Distributed Data Fusion for Network-Centric Operations. CRC Press. Nov 2012.
Abstract: With the recent proliferation of service-oriented architectures (SOA), cloud computing technologies, and distributed-interconnected systems, distributed fusion is taking on a larger role in a variety of applications—from environmental monitoring and crisis management to intelligent buildings and defense. Drawing on the work of leading experts around the world, Distributed Data Fusion for Network-Centric Operations examines the state of the art of data fusion in a distributed sensing, communications, and computing environment. Get Insight into Designing and Implementing Data Fusion in a Distributed Network Addressing the entirety of information fusion, the contributors cover everything from signal and image processing, through estimation, to situation awareness. In particular, the work offers a timely look at the issues and solutions involving fusion within a distributed network enterprise. These include critical design problems, such as how to maintain a pedigree of agents or nodes that receive information, provide their contribution to the dataset, and pass to other network components. The book also tackles dynamic data sharing within a network-centric enterprise, distributed fusion effects on state estimation, graph-theoretic methods to optimize fusion performance, human engineering factors, and computer ontologies for higher levels of situation assessment. A comprehensive introduction to this emerging field and its challenges, the book explores how data fusion can be used within grid, distributed, and cloud computing architectures. Bringing together both theoretical and applied research perspectives, this is a valuable reference for fusion researchers and practitioners. It offers guidance and insight for those working on the complex issues of designing and implementing distributed, decentralized information fusion.

Ana B. Lago Vilariño and Iván Pretel García. E-learning platform for Integrated Management of Documents based on Automatic Digitalization. On IEEE-RITA: Revista Iberoamericana de Tecnologías del Aprendizaje AUG. 2012 VOL. 7 Number 3 ISSN: 932-8540
Abstract: Despite the advances in computing, traditional paper is still widely used in learning and knowledge work. Most current learning technologies do not account for this paper-centric practice and focus on a complete digitization of learning contents, activities, and communication. This paper presents an e-learning platform that combines work with printed and digital documents. It integrates pen-and-paper-based interaction techniques that enable users to manage their digitized documents. Moreover, this platform integrates different e-learning platforms providing a single intuitive interface to management them. Finally, a case study of the use of the platform in university education is presented.

Iván Pretel García and Ana B. Lago Vilariño. Mobile Interaction Capturing System in Real Environments. On Computer Technology and Application AUG. 2012 VOL. 3 Number 8 ISSN: 1934-7332
Abstract: Mobile applications are being used in a great range of fields and application areas. As a result, many research fields have focused on the study and improvement of such devices. The current Smartphones are the best example of the research and the evolution of these technologies. Moreover, the software design and development is progressively more focused on the user; finding and developing new mobile interaction models. In order to do so, knowing what kind of problems the users could have is vital to enhance a bad interaction design. Unfortunately, a good software quality evaluation takes more time than the companies can invest. The contribution revealed in this work is a new approach to quality testing methodology focused on mobile interactions and their context in use where external capturing tools, such as cameras, are suppressed and the evaluation environments are the same as the user will use the application. By this approach, the interactions can be captured without changing the context and consequently, the data will be more accurate, enabling the evaluation of the quality-in-use in real environments.

Abstract: This work introduces a novel access control solution for infrastructures composed of highly constrained devices which provide users with services. Low energy consumption is a key point in this kind of scenarios given that devices usually run on batteries and are unattended for long periods of time. Our proposal achieves privacy, authentication, semantic security, low energy and computational demand and device compromise impact limitation on a simple manner. The access control provided is based on user identity and time intervals. We discuss these properties and compare our proposal to previous related work.

Abstract: Several toolkits have been proposed in order to ease the development of context-aware systems, providing high-level programming interfaces to manage context data. One of the main tasks in the development of such systems is the definition of user situations that have to be identified by the system in order to adapt its behaviour. These situations are best defined by domain experts, but usually they do not have programming skills. Apart from that, there is a lack of methodologies to guide the development process. This paper presents a methodology based on the definition of situations that is designed to involve domain experts in the development process. This way, they can support programmers in the definition of the required situations. Also, a web-based platform has been implemented in order to manage context data without any programming skills. This way, domain experts can also configure the situations to be detected by the system.

In Proceedings of 6th International Conference on Ubiquitous Computing and Ambient Inteligence (UCAmI'12). Lecture Notes in Computer Science 2012, pp 298-305. ISBN: 978-3-642-35376-5.

Abstract: Recommender systems have increased their impact in the Internet due to the unmanageable amount of items that users can find in the Web. This way, many algorithms have emerged filtering those items which best fit into users’ tastes. Nevertheless, these systems suffer from the same shortcoming: the lack of new user data to recommend any item based on their tastes. Social relationships gathered from social networks and intelligent environments become a challenging opportunity to retrieve data from users based on their relationships, and social network analysis provides the demanded techniques to accomplish this objective. In this paper we present a methodology which uses users’ social network data to generate first recommendations, alleviating the cold-user limitation. Besides, we demonstrate that it is possible to reduce the cold-user problem applying our solution to a recommendation system environment.
Keywords: Recommender Systems; Social Network Analysis; Cold-user.

Abstract: Since Sir Tim Berners-Lee announced the best practices to publish semantic data through the Web, Linked Data principles have been introduced into a wide variety of application domains. This usage of Linked Data eases the enrichment of offered data in a grade that the semantic data that not applies the Linked Data principles never would achieve. In this paper, we present LinkedQR1 , a tool to improve the collaboration between QR codes and Linked Data; and a case study based on the tourism sector located into an art gallery.

Abstract: Research community has shown a great interest in OWL on tologies as a context modeling tool for semantic environments. OWL ontologies are characterized by its expressive power and are based on description logics. However, they have limitations when dealing with uncertainty and vagueness knowledge. To overcome these caveats, some approaches have been proposed. This work presents a novel approach to deal with uncertainty in semantic environments, called TURAMBAR.
