The AXMEDIS events offer venues for exchanging concepts, requirements, prototypes, research ideas, and findings which could contribute to academic research and also benefit business and industrial communities. In the Internet as well as in the digital era, cross-media production and distribution represent key developments and innovations that are fostered by emergent technologies to ensure better value for money while optimising productivity and market coverage

    Metadata enhanced content management in media companies

    Media companies are facing new opportunities and challenges. Communications, computing, and content industries are converging into a single, horizontally connected content value chain, where changes are frequent and activities are highly interdependent. However, before convergence and digital content are taken seriously, media companies must understand what is expected from them, how their operations will be affected, and why they should be involved. The production, distribution, and use of content rely heavily on computers and automation. This requires the content essence to be enhanced with explicit descriptions of semantics, or more specifically, semantic metadata. However, semantic metadata is useful only if its nature is understood clearly, and when its structure and usage are well defined. For this purpose, ontologies are needed to capture the essential characteristics of the content domain into a limited set of meaningful concepts. The creation and management of ontologies and semantic metadata require skills and activities that do not necessarily exist in traditional print-based publishing or broadcasting. Companies developing ontologies must understand the essential characteristics of available content, user needs, and planned or existing use of content. Furthermore, they must be able to express this information explicitly in an ontology and then reflect changes in the environment back to that ontology. Content production and distribution should be flexible and able to support the reuse of content. This thesis introduces two abstract models, a component model and a process model. Both models assist in the understanding and analysis of electronic publishing of content for multiple media products and on multiple media platforms. When semantic metadata, ontologies, and improved publishing processes are available, new advanced content-based products, such as personalized information feeds, are possible. The SmartPush project, for which the author was the project manager and worked as a researcher, has shown that semantic metadata is useful in creating advanced content-based products, and that media companies are willing to alter their existing publishing processes. Media companies participating in the SmartPush project have acknowledged the impact of our work on their plans and operations. Their acknowledgement emphasizes the practical importance of semantic metadata, ontologies, improved electronic publishing process, and personalization research.reviewe

    Effektive Kommunikation von Gefahrenabwehrinformationen vor, während und nach einer Katastrophe kann Leben retten und dazu beitragen, dass Betroffene Zugang zu Rettungsmaßnahmen erhalten. In dieser Hinsicht dienen Meldungen dazu, die Allgemeinheit zu informieren und deren Handlungen zu beeinflussen. Dennoch bleiben gewünschte Reaktionen in vielen Fällen aus, oder erweisen sich als unzureichend um den Folgen von Katastrophen entgegenzuwirken. Somit wird trotz der Veröffentlichung von Warnungen eine große Zahl an Menschen von Katastrophen beeinträchtigt oder kommt sogar zu Tode. Außerdem leiden viele Menschen im Anschluss an Katastrophen weiter, obwohl Hilfe zur Verfügung steht. Die Absicht dieser Forschungsarbeit besteht darin festzustellen, welche Faktoren effektive Kommunikation innerhalb einer Katastrophensituation erschweren. Obwohl die jeweiligen Akteure im Katastrophenkommunikationssystem darauf abzielen die Allgemeinheit zu informieren, berücksichtigen sie Kommunikationsprobleme oft nicht angemessen. Allerdings können Kommunikationsprobleme der Grund dafür sein, dass Meldungen die Allgemeinheit entweder nicht erreichen, oder nicht vollständig verstanden werden. Je weniger Informationen der Öffentlichkeit zur Verfügung stehen, desto größer ist die Wahrscheinlichkeit, dass Menschen Entscheidungen fällen, die ihr Leben gefährden. Meine Herangehensweise an dieses Problem erfolgte von der Systemperspektive. Ziel eines jeden Katastrophenkommunikationssystem besteht darin, die öffentliche Sicherheit in Bezug auf eine Katastrophensituation zu gewährleisten. Dieses Ziel wird durch den Kommunikationsvorgang erreicht. In aller Regel umfasst ein Katastrophenkommunikationssystem ein komplexes Netzwerk aus Menschen, Organisationen und Kommunikationskanälen. Hierbei fungiert das Katastrophenkommunikationssystem im Rahmen einer Katastrophenumgebung, die sich fortlaufend ändert. Die Kombination aus einem komplexen Kommunikationssystem zum Einen und einer dynamischen Katastrophenumgebung zum Anderen verschärft Kommunikationsprobleme. Mit Hilfe von drei Fallstudien wurde ein tiefgreifendes Verständnis erlangt, wie Gefahrenabwehrinformationen die Allgemeinheit während einer Katastrophensituation tatsächlich erreichen. In diesem Zusammenhang wurden Typhoon Haiyan und Hagupit auf den Philippinen sowie das Gorkha Erdbeben in Nepal untersucht. Quantitative Umfragen mit Individuen und lokalen Amtsträgern aus Katastrophengebieten wurden durchgeführt. Mit Schlüsselpersonen aus verschiedenen Regierungs- und Nichtregierungsorganisationen wurden qualitative Befragungen absolviert. Die Ergebnisse der Fallstudien erläutern wie Individuen und Regierungsvertreter in beiden Ländern im Verlauf einer Katastrophensituation einerseits Informationen ersuchen und andererseits miteinander kommunizieren. Ebenso zeigen die Ergebnisse, dass Verhaltensweisen hinsichtlich Beschaffung und Kommunikation von Informationen von Geschlecht, Standort und Alter abhängen. Zugleich haben die Fallstudien dazu beigetragen, die verschiedenen Akteure innerhalb des Katastrophenkommunikationssystems zu benennen und ihre Beziehungen untereinander zu verdeutlichen. Des Weiteren wurden thematische Analysen ausgearbeitet, um fundierte Kenntnisse über charakteristische Inhalte der Gefahrenabwehrmeldungen zu gewinnen. Dazu wurden für insgesamt 21 Katastrophenereignisse die dazugehörigen Meldungen bezüglich der Sachlage ausgewertet. Die thematischen Analysen führten zur Entwicklung von Klassifikationsschemen. Diese unterteilen den Inhalt einer Gefahrenabwehrmeldung in bestimmte Kategorien um weiterführende Untersuchungen unternehmen zu können. Vor diesem Hintergrund wird eine Methodik zur Analyse der Gefahrenabwehrmeldungen in Echtzeit vorgestellt. Durch das Zusammenführen der Fallstudienergebnisse, der thematischen Analysen sowie der Literatur ist ein konzeptionelles Modell für ein typisches Katastrophenkommunikationssystem entstanden. Der Zweck des Modells liegt darin, die Diskussion bezüglich Katastrophenkommunikationsplänen und Problemlösungsvorschlägen zu verbessern. Im Hinblick auf die ermittelten Hindernisfaktoren gegenüber effektiver Kommunikation findet dieses Modell Anwendung bei der Frage, wie es Akteure dabei unterstützen kann eben solche Hindernisfaktoren zu beheben. Schlussendlich haben die Ergebnisse Auswirkungen auf alle Individuen und Organisationen, die bestrebt sind mit der Öffentlichkeit im Verlauf einer Katastrophe zu kommunizieren

    João Carlos Correia, Anabela Gradim e Ricardo Morais (Eds.) (2020) Pathologies and dysfunctions of democracy in the media context - 1st volume.In the last decade, from a communicative point of view, a lot of novelties and changes shaped the traditional public sphere, Donald Trump's election in the United States of America, the Brexits, the rising of the several xenophobic and ultra-nationalist threats emerging in different geographical and political contexts, the populism phenomena, as well as the te debate on Cyber surveillance, counter-information, and the so-called "fake news" has drawn attention to some dystopian portrays conceived in the 20th Century which is now being considered an appropriate depiction of democracy and political communication's new pathologies. The book joins together researchers from Communication Sciences and related areas (Political Science, Political Theory, Political Philosophy, Political Sociology, Arts, and others), with particular emphasis on those interested in political communication around a unifying common axis: the pathologies and dysfunctions of democracy, in media contexts, in different aspects of their involvement with the media such as the media representation of these pathologies and dysfunctions; the impact of the media in the functioning of democratic institutions; the interference of political agents in journalistic information; the relationship between media and political institutions in the processes of public opinion building. Particularly, on this volume one addresses to the topic of surveillance. Within digital social networks and infotainment, invisibility, the right to be forgotten, and the reserve of a private life acquire an almost subversive nature in an age defined by hiper-communication. Simultaneously, the media staging of power mobilizes protagonists to a reality in which rationality and public responsibility are confronted with multiple risks of scandal arising from a permanent state of collective scrutiny. "Scandalogy" is a concept already used to project the study of image crisis’ phenomena, increasingly emerging due to the opportunities of political exposure.info:eu-repo/semantics/publishedVersio

    An aesthetics of touch: investigating the language of design relating to form

    How well can designers communicate qualities of touch? This paper presents evidence that they have some capability to do so, much of which appears to have been learned, but at present make limited use of such language. Interviews with graduate designer-makers suggest that they are aware of and value the importance of touch and materiality in their work, but lack a vocabulary to fully relate to their detailed explanations of other aspects such as their intent or selection of materials. We believe that more attention should be paid to the verbal dialogue that happens in the design process, particularly as other researchers show that even making-based learning also has a strong verbal element to it. However, verbal language alone does not appear to be adequate for a comprehensive language of touch. Graduate designers-makers’ descriptive practices combined non-verbal manipulation within verbal accounts. We thus argue that haptic vocabularies do not simply describe material qualities, but rather are situated competences that physically demonstrate the presence of haptic qualities. Such competencies are more important than groups of verbal vocabularies in isolation. Design support for developing and extending haptic competences must take this wide range of considerations into account to comprehensively improve designers’ capabilities

    Semantic discovery and reuse of business process patterns

    Get PDF
    Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse

    Thesis (S.M.)--Massachusetts Institute of Technology, System Design and Management Program, 2009.Includes bibliographical references (p. 113-115).Mobile web applications refer to web applications on mobile devices, aimed at personalizing, integrating, and discovering mobile contents in user contexts. This thesis presents a comprehensive study of mobile web applications by proposing a new taxonomy for mobile web applications, and conducting a business analysis in the field of mobile web applications. The thesis reviews the current surrounding environment for mobile web applications, namely, web 2.0 and 3.0, wireless communication technology, and Smartphone platform. The recent entry and success of Apple's iPhone greatly enhanced the public awareness of the Smartphone technology. Google's release of open-source Android platform and T-Mobile's deployment of Android-powered "Dream" Smartphone not only intensify the competition among suppliers, but also provide an open-source foundation for mobile web applications. This thesis introduces a new mobile web application taxonomy to systematically study the values and the groupings of the mobile web applications. By introducing features and categories, the taxonomy provides a framework so the related companies and businesses can be comparatively analyzed and summarized. Selected case companies are studied in the light of the taxonomy. The thesis discusses the key issues of mobile web aggregation, namely, mobile application development platform, context modeling, mobile user interface, mobile application logic, and mobile web aggregation strategy.(cont.) "System Thinking" is applied to the management of mobile web application business. The market ecosystem, the value proposition, and the revenue model for mobile web application are described. A system dynamic model is constructed to understand the dynamic among the key factors in the mobile web business. Experimental results are reported in the thesis.by Kevin Hao Liu.S.M
