Towards a multimedia formatting vocabulary

Time-based, media-centric Web presentations can be described declaratively in the XML world through the development of languages such as SMIL. It is difficult, however, to fully integrate them in a complete document transformation processing chain. In order to achieve the desired processing of data-driven, time-based, media-centric presentations, the text-flow based formatting vocabularies used by style languages such as XSL, CSS and DSSSL need to be extended. The paper presents a selection of use cases which are used to derive a list of requirements for a multimedia style and transformation formatting vocabulary. The boundaries of applicability of existing text-based formatting models for media-centric transformations are analyzed. The paper then discusses the advantages and disadvantages of a fully-fledged time-based multimedia formatting model. Finally, the discussion is illustrated by describing the key properties of the example multimedia formatting vocabulary currently implemented in the back-end of our Cuypers multimedia transformation engine

Using the semantic web to navigate conceptual spaces: an application for the philosophical domain

The semantic web offers new possibilities in the eLearning area, which are dependent at least on two factors: the increasing availability of resources on the web and the semantic power of their meta-descriptions. This paper looks at this second issue, and tries to determine the general framework and the important features of the metadata for a specific domain, philosophy. Thanks to an adequate conceptualization, in fact, it is possible to recollect resources and compose them into a novel narrative, in order to provide specific learning services

Methods and Technologies for Digital Preservation of Analog Audio Collections

This paper is a consideration of some of the challenges libraries and other institutions face in the digitization of analog audio collections for preservation and access. The intent of this study is to demonstrate that such an existing analog audio collection can be digitized, described, stored, and preserved using currently available and emerging technologies. Consideration was accorded to a broad range of topics related to the creation of enduring digital audio collections. It is hoped that this effort will illuminate possible paths to successful preservation of audio collections while also vastly improving access to them. Furthermore, the study will demonstrate that libraries and other institutions that possess similar multimedia assets may have access to effective and economical means of transforming isolated and moribund materials into persistent, valuable, and widely available multimedia documents

Sistema para navegação web usando imagem e vídeo

Dissertação para obtenção do Grau de Mestre em Engenharia InformáticaAo acompanhar o desenvolvimento da tecnologia e de forma a despertar o interesse dos visitantes, museus e galerias de arte têm criado sistemas capazes de suportar a interação entre o público e as suas obras, através de interfaces inovadoras. A construção de museus virtuais e de novas técnicas de visualização de imagem ou fotografia têm atraído cada vez mais visitantes, devido à facilidade de consulta, navegação e qualidade gráfica e artística desses mesmos sistemas. A criação de sistemas capazes de permitir o acesso a todo o público, por exemplo através da Internet, possibilita o acesso a informação relacionada com as exposições e a troca de experiências entre utilizadores. A solução desenvolvida é suportada por uma plataformaWeb que permite a navegação e exploração de uma exposição de artes plásticas que ocorreu no passado e da qual resta apenas um arquivo fotográfico. A navegação virtual será feita de forma a respeitar a organização espacial de fotografias, usando sistemas de colagem e integração de imagem. Através deste processo, será possível consultar as obras, oferecendo a possibilidade de visualizar em alta resolução, permitindo também efetuar pesquisas por obra ou autor. A implementação de uma interface atrativa e de fácil utilização por parte do utilizador é um elemento fundamental para o sucesso deste sistema. Daí que o uso de tecnologias, que permitam a implementação de novos métodos para a construção destes sistemas, seja algo que tenha que estar presente principalmente na implementação da componente visual e da interação com o utilizador. A avaliação do sistema será feita com base em testes, em que serão selecionados utilizadores pertencentes a vários grupos diferentes, recolhendo informação sobre a experiência da utilização

A component framework for personalized multimedia applications

Eine praktikable Unterstützung für eine dynamische Erstellung von personalisierten Multimedia-Präsentationen bieten bisher weder industrielle Lösungen noch Forschungsansätze. Mit dem Software-technischen Ansatz des MM4U-Frameworks („MultiMedia For You“) wird erstmals eine generische und zugleich praktikable Unterstützung für den dynamischen Erstellungsprozess bereitgestellt. Das Ziel des MM4U-Frameworks ist es den Anwendungsentwicklern eine umfangreiche und anwendungsunabhängige Unterstützung zur Erstellung von personalisierten Multimedia-Inhalten anzubieten und damit den Entwicklungsprozess solcher Anwendungen erheblich zu erleichtern. Um das Ziel eines Software-Frameworks zur generischen Unterstützung der Entwicklung von personalisierten Multimedia-Anwendungen zu erreichen, stellt sich die Frage nach einer geeigneten Software-technischen Unterstützung zur Entwicklung eines solchen Frameworks. Seit der Einführung von objektorientierten Frameworks, ist heute die Entwicklung immer noch aufwendig und schwierig. Um die Entwicklungsrisiken zu reduzieren, sind geeignete Vorgehensmodelle und Entwicklungsmethoden erstellt worden. Mit der Komponenten-Technologie sind auch so genannte Komponenten-Frameworks entstanden. Im Gegensatz zu objekt-orientierten Frameworks fehlt derzeit jedoch ein geeignetes Vorgehensmodell für Komponenten-Frameworks. Um den Entwicklungsprozess von Komponenten-Frameworks zu verbessern ist mit ProMoCF („Process Model for Component Frameworks“) ein neuartiger Ansatz entwickelt worden. Hierbei handelt es sich um ein leichtgewichtiges Vorgehensmodell und eine Entwicklungsmethodik für Komponenten-Frameworks. Das Vorgehensmodell wurde unter gegenseitigem Nutzen mit der Entwicklung des MM4U-Frameworks erstellt. Das MM4U-Framework stellt keine Neuerfindung der Adaption von Multimedia-Inhalten dar, sondern zielt auf die Vereinigung und Einbettung existierender Forschungsansätze und Lösungen im Umfeld der Multimedia-Personalisierung. Mit so einem Framework an der Hand können Anwendungsentwickler erstmals effizient und einfach eine dynamische Erstellung ihrer personalisierten Multimedia-Inhalte realisieren
