Indización automática de vídeo

After an initial discussion of the problems presented by image and video indexing as compared to text indexing, the authors describe some of the basic techniques for automatic video indexing. The content-based retrieval paradigm and some automatic methods for segmentation and key-frame identification are further described. Certain low-level parameters for identifying an image are also introduced. The authors discuss the drawbacks of such automatic methods based solely on the image and give examples from projects using accompanying nformation as well, such as audio and captions. The article concludes by pointing out that the use of standards, like Mpeg-7, can promote the development of new and richer applications based on video

Mossèn Jaume Ferrer de Blanes. Un testament hològraf del segle XVI

L'any 1526, després d'una vida plena de peripècies viatjant de llevant a ponent de la Mediterrània, de Jerusalem a Barcelona, mossès Ferrer, mercader, lapidari, cosmògraf, procurador reial i nobiliari, clavari del vescomtat de Cabrera i de Bas, escriptor dantista i espòs fidel, nascut a Vidreres cap al 1445, va escriure el seu testament.

Vocabulari d'estils literaris personals. Anàlisi, avaluació i propostes d'expansió

Aquest treball presenta un conjunt de termes d'ús comú dins els textos de crítica literària. Resolen una de les necessitats dels crítics, la denominació dels trets que defineixen les obres de la literatura catalana, i, alhora, fan una aportació definitiva a la terminologia universal en l'àmbit en què els Països Catalans han destacat de sempre, d'ara i de demà: la literatura.This paper presents a set of terms commonly used in the texts of literary criticism. They provide a solution to critics’ needs and the names of the features that define the works of Catalan literature and, at the same time, they also make a definitive contribution to the universal terminology in a field in which the Catalanspeaking area has always stood out: literature

Towards a practitioner-centered approach to the design of e-learning competence editors

Girardin, F., Ayman, M., & Josep, B. (2007). Towards a practitioner-centered approach to the design of e-learning competence editors. In T. Navarrete, J. Blat & R. Koper (Eds.), Proceedings of the 3rd TENComptence Open workshop 'Current Research on IMS Learning Design and Lifelong Competence Development Infrastucture' (pp. 99-104). June, 20-21, 2007, Barcelona, Spain: TENCompetence.This article reports on the background research on requirements and current approaches to editors for learning curriculum designers. First we take a critique look at the state of the art in the domain of learning activity editors. We then look back in the information visualization and interaction literature to discuss the design challenged of such tools. From these current theories and applied works we define a set a rules that are crucial for the design of CDP editors based developed on top of complex e-learning models. Finally, we exemplify the set of design rules with a prototype integrating tightly coupled map-based and Gantt chart views.The work on this publication has been sponsored by the TENCompetence Integrated Project that is funded by the European Commission's 6th Framework Programme, priority IST/Technology Enhanced Learning.

Current Research on IMS Learning Design and Lifelong Competence Development Infrastructures

These proceedings consist of the papers presented at the Third TENCompetence Open Workshop which were accepted after peer reviewing. The workshop theme was Current Research on IMS Learning Design and Lifelong Competence Development Infrastructures. The workshop took place at the Universitat Pompeu Fabra, Barcelona, Spain, on the 21st and 22nd of June 2007

Modifying Entity Relationship Models for Collaborative Fiction Planning and its Impact on Potential Authors

We propose a modified Entity Relationship (E-R) model, traditionally used for software engineering, to structure, store and share plot data. The flexibility of E-R modelling has been demonstrated by its decades of usage in a wide variety of situations. The success of the E-R model suggests that it could be useful for collaborating fiction authors, adding a certain degree of computational power to their process. We changed the E-R model syntax to better suit the story plans, switching the emphasis from generic types to instanced story entities, but preserving relationships and attributes. We conducted a small-scale basic experiment to study the impact of using our modified E-R model on authors when understanding and contributing into a pre-existing fiction story plan. The results analysis revealed that the E-R model supports authors as effectively as written text in reading comprehension, memory, and contributing. In addition, the results show that, when combined together, the written text and the E-R model help participants achieve better comprehension--always within the frame of our experiment. We discuss potential applications of these findings

Supporting Usability and Reusability Based on eLearning Standards

The IMS-QTI, and other related specifications have been developed to support the creation of reusable and pedagogically neutral assessment scenarios and content, as stated by the IMS Global Learning Consortium. In this paper we discuss how current specifications both constrain the design of assessment scenarios, and limit content reusability. We also suggest some solutions to overcome these limitations. The paper is based on our experience developing and testing an IMS QTI Lite compliant assessment authoring tool, QAed. It supports teacher centering, which is quite neglected when designing such tools. In the paper we also discuss how to make compatible standards support and user centering in eLearning applications and provide some recommendations for the design of the user interfaces
