Forms and functions of intertextuality in academic tweets composed by research groups

This paper explores the forms and functions of intertextuality in academic tweets composed by research groups. Academic tweets are dialogic and intertextual texts, usually composed by incorporating other voices and taking up text-visual elements from other contexts. Based on the analysis of 300 tweets taken from the Twitter accounts of four research groups in two different disciplines (Chemistry and Medicine), this study investigates the ways in which intertextual practices contribute to the communicative purposes of the genre. The analysis shows that the affordances of Twitter (e.g. hyperlinking, modularity, multimodality) and the purpose of academic tweets shape the forms and functions of intertextuality in these tweets. When composing these tweets academics both reconfigure well-established forms of intertextuality and display novel forms which help them to promote their research, negotiate their relationships with their readers, and share content with diverse audiences

IRISA at TrecVid2015: Leveraging Multimodal LDA for Video Hyperlinking

International audienceThis paper presents the runs that we submitted in the context of the TRECVid 2015 Video Hyperlinking task. The task aims at proposing a set of video segments, called targets, to complement a query video segment defined as anchor. We used automatic transcripts and automatically extracted visual concept as input data. Two out of four runs use cross-modal LDA as a means to jointly make use of visual and audio information in the videos. As a contrast, one is based solely on visual information, and a combination of the cross-modal and visual runs is considered. After presenting the approaches, we discuss the performance obtained by the respective runs, as well as some of the limitations of the evaluation process

A task category space for user-centric comparative multimedia search evaluations

In the last decade, user-centric video search competitions have facilitated the evolution of interactive video search systems. So far, these competitions focused on a small number of search task categories, with few attempts to change task category configurations. Based on our extensive experience with interactive video search contests, we have analyzed the spectrum of possible task categories and propose a list of individual axes that define a large space of possible task categories. Using this concept of category space, new user-centric video search competitions can be designed to benchmark video search systems from different perspectives. We further analyse the three task categories considered so far at the Video Browser Showdown and discuss possible (but sometimes challenging) shifts within the task category spac

Teaching "writing 2.0"

Diese Diplomarbeit beschäftigt sich mit dem Web 2.0, seiner Auswirkung auf das Wesen der Schreibkomptenz und der schriftlichen Kommunikation (‚Writing‘), und dessen Implikationen für den Fremdsprachenunterricht Englisch. Nach einer Begriffsdefinition von ‚Writing‘ wird das Konzept von ‚Literacy‘ beleuchtet, das heutzutage weit über die traditionelle Lese- und Schreibkompetenz hinausgeht, und deshalb von mehreren Quellen nur als Mehrzahlform geführt wird (‚New Literacies‘). Diese neuen ‚Literacies‘ definieren sich im digitalen Zeitalter vor allem durch das Medium des Bildschirms, das die traditionellen textlastigen Strukturen aufbricht, und sich zunehmend am Bildhaften und der Kombination von multimodalen Inhalten orientiert. Nach einem Überblick über traditionelle Lernmodelle für die Vermittlung der Schreibkompetenz, wird auf neue Technologien und ihre Implikationen für den Fremdsprachenunterricht eingegangen. Im Weiteren, finden sich eine Beschreibung des „Connectivism“ als Lerntheorie für das digitale Zeitalter, sowie eine Analyse des GERS (Gemeinsamer Europäischer Referenzrahmen) und der österreichischen AHS Lehrpläne bezüglich ihrer Inhalte zur Schreibkompetenz und zu neuen Technologien. Anschließend erklärt die Arbeit die Besonderheiten des Web 2.0, und beschreibt vier Applikationen (Weblogs, Twitter, Wikis und Online Document Editors) in ihrer Funktionalität sowie ihrem Unterrichtseinsatz. Weiters geht die Arbeit auch auf ein didaktisches Modell der „New London Group“ ein, das sich von der Vermittlung von einzelnen Sprachfertigkeiten löst, und sich an der Verknüpfung von verschiedenen Design Elementen in der Textkomposition orientiert. Ergänzend finden sich Überlegungen zu einer Pädagogik 2.0, mit Prinzipien wie Lerner-Autonomie und lernerzentriertem Unterricht. Abschließend werden Evaluierungskriterien zur Vermittlung einer ‚Writing 2.0‘ Kompetenz durch Web Applikationen, definiert, und in einer Evaluierung von Wikis und Weblogs angewendet

Deliverable D5.1 LinkedTV Platform and Architecture

The objective of Linked TV is the integration of hyperlinks in videos to open up new possibilities for an interactive, seamless usage of video on the Web. LinkedTV provides a platform for the automatic identification of media fragments, their metadata annotations and connection with the Linked Open Data Cloud, which enables to develop applications for the search for objects, persons or events in videos and retrieval of more detailed related information. The objective of D5.1 is the design of the platform architecture for the server and client side based on the requirements derived from the scenarios defined in WP6 and technical needs from WPs 1-4. The document defines workflows, components, data structures and tools. Flexible interfaces and an efficient communications infrastructure allow for a seamless deployment of the system in heterogeneous, distributed environments. The resulting design builds the basis for the distributed development of all components in WP1-4 and their integration into a platform enabling for the efficient development of Hypervideo applications

Hypermediating Journalistic Authority: the case of Ethiopian private media

This study, situated at the nexus between journalism, technology and society, focuses on the mediation of authority in the hypertextual environment. It explored the technology- journalism relationship as deployed in the Ethiopian media context where the private press is marginalized from access to official information. This particular context is important to examine the deployment of hyperlinks not only as a natural adoption but as a survival mechanism as well as a locus of meaning where authority is mediated in linking strategies. As such, the study selected two private news sites in this media landscape, Addis Standard and Ethiopia Observer, based on their frequent use of hyperlinks in their news reporting. With a critical approach drawing upon qualitative and quantitative social semiotics, the study conducted a multi-stage analysis following the links trajectory, navigational pathways, link precision, link destination and authorship. Data was collected over two periods to examine the interplay of the socio-political context in hyperlinking strategies; three months of initial data and six months of the ongoing Tigray war. Though the general linking patterns, such as total number of links, showed big gaps over the two periods, a notable rise for Addis Standard and a dramatic decline for Ethiopia Observer, in contrast to the global trend, both prioritized external linking. As the study progressed, in addition to the differential utilization of hyperlinks between the two news sites as a reflection of their status in the society, the study also revealed customization of use attuned to material realities. With a relatively strong presence in the Ethiopian media landscape and better access to sources and events, AS uses a notable proportion of its hyperlinking to call attention to its original reports while EO, a diasporic outlet frequently uses external linking to fulfill its information needs. Hyperlinking is also used by AS to show professional interventions in recycled stories for contextualization. Despite the methodological constraints of the study due to different external factors, the study showed the potential of hyperlinking strategies to shape the content of news. This was demonstrated by how EO gravitated toward government outlets in the second dataset establishing the “law enforcement operations” narrative of the government over that of the atrocities against civilians reported by popular international outlets who extensively reported the war

Moving Composition: Writing in a Mobile World

We live in an increasingly mobile society on many levels. Mobile devices, including the smartphone, tablet, and wearables, allow for composing and communicating from anywhere and in new ways, a phenomenon that is especially deserving of attention by composition studies scholars and teachers. Mobile composition processes are impacted by the symmetry of humans and technology as each equally shapes one another. This interplay of mobile devices (including wearables) and humans impacts composition ecologies, processes, and definitions of writing. The role of analog mobile writers also informs our current practices and approaches to a mobile composition as many writers have sought to write on the move. Educational researchers identify mobile learning as unique with attributes not afforded in analog or tethered learning environments. Mobile composition is poised to take advantage of the authentic, collaborative, and new opportunities for making meaning that exist in this form of teaching and learning. Mobile composition also transcends the literature from established composition studies and mobile learning frameworks by residing and inventing the burgeoning digital apparatus, electracy, that follows and extends the practices of oral and literate civilizations. Electracy\u27s teaching and learning corollary, post(e)-pedagogy, offers ways to make use of mobile devices in this new framework. Finally, this dissertation project includes a mobile composition course prototype that models a post(e)-pedagogical approach and encourages further critical exploration and invention of communication practices with mobile devices, especially by composition faculty and students but in higher education overall
