    In this paper we present a novel interactive multimodal learning system, which facilitates search and exploration in large networks of social multimedia users. It allows the analyst to identify and select users of interest, and to find similar users in an interactive learning setting. Our approach is based on novel multimodal representations of users, words and concepts, which we simultaneously learn by deploying a general-purpose neural embedding model. We show these representations to be useful not only for categorizing users, but also for automatically generating user and community profiles. Inspired by traditional summarization approaches, we create the profiles by selecting diverse and representative content from all available modalities, i.e. the text, image and user modality. The usefulness of the approach is evaluated using artificial actors, which simulate user behavior in a relevance feedback scenario. Multiple experiments were conducted in order to evaluate the quality of our multimodal representations, to compare different embedding strategies, and to determine the importance of different modalities. We demonstrate the capabilities of the proposed approach on two different multimedia collections originating from the violent online extremism forum Stormfront and the microblogging platform Twitter, which are particularly interesting due to the high semantic level of the discussions they feature

    Satellite-enabled interactive education: scenarios and systems architectures

    Get PDF
    There are specific sectors of the economy that can benefit from satellite-based tele-education. Areas, such as maritime and agriculture, share common needs for both broadband connectivity at remote geographical areas that cannot otherwise be covered, and for innovative content for tele-education purposes. Furthermore, each area has special requirements with regard to the type of content to be delivered. In this paper we propose a set of architectural designs and case scenarios that will realise such interactive end-to-end education systems based on satellite communications. Services requirements in this setting are also identified and discussed

    A Pedagogy for Original Synners

    Part of the Volume on Digital Young, Innovation, and the UnexpectedThis essay begins by speculating about the learning environment of the class of 2020. It takes place entirely in a virtual world, populated by simulated avatars, managed through the pedagogy of gaming. Based on this projected version of a future-now-in-formation, the authors consider the implications of the current paradigm shift that is happening at the edges of institutions of higher education. From the development of programs in multimedia literacy to the focus on the creation of hybrid learning spaces (that combine the use of virtual worlds, social networking applications, and classroom activities), the scene of learning as well as the subjects of education are changing. The figure of the Original Synner is a projection of the student-of-the-future whose foundational literacy is grounded in their ability to synthesize information from multiple information streams

    Interactive Newsprint: The Future of Newspapers? Printed electronics meets hyperlocal and community co-design

    Get PDF
    The news industry is currently in a well-documented state of flux, with publishers from across the developed world examining new business models, reinterpreting existing relationships between their income streams and readers, while maintaining their ability to generate editorial output that is relevant and interesting to the communities they cover. Interactive Newsprint seeks to add a new and revolutionary dimension to this media evolution by asking: can printed electronics and internet-enabled paper (technologies that utilise standard paper and printing processes and through conductive ink and battery power offer capacitive touch interactions similar to smartphones and tablets) create a new way of transmitting community-based news and information? Utilising co-design techniques and practices, the project seeks to produce community- relevant hyperlocal text and audio content and place it on a centuries-old platform: the newspaper. As a result of the paper's internet connectivity, the project is also examining potential benefits of transplanting some online features such as analytic data on user interactions. Led by the School of Journalism, Media and Communication (JoMeC) at the University of Central Lancashire (UCLan), the 18-month, EPRSC-funded project is therefore examining the potential for community co-design and printed electronics to transform paper- based news and information for the 21st Century, along with revenue and data generation that is unique to digital formats such as websites, social networks, smartphones and tablets. Building on work carried out on the EPSRC-funded Bespoke project, researchers from UCLan, University of Dundee, University of Surrey and commercial printed electronics firm Novalia are prototyping a series of paper-based community news platforms that are populated by content produced by community reporters and generated through an iterative co-design process. This paper will outline the methodology, technological potential of interactive newsprint and how the project is looking to embed analytic data into traditional printed-paper formats. It will also focus on how members of the Preston community are shaping both the news and platform over the 18-month process. As the project is mid-way through, the paper will present an overview of the project to date, outline the design methodology and describe and demonstrate the early-stage prototypes. The paper will also hint at new editorial construction practices as community and professional reporters all contribute to the hyperlocally-themed editorial output. The authors will present a discussion of the theoretical framework that underpins the project as a whole. In addition to the practical illustrations, the paper will outline the authors' initial thoughts on how interactive newsprint – through its internet connectivity and potential for data transfer – could revolutionise editorial and advertorial relationships

    Migrating existing multimedia courseware to Moodle

    Get PDF
    Open source course management systems offer increased flexibility for instructors and instructional designers. Communities can influence the development of these systems and on an individual basis, the possibility to modify the system software exists. Migrating existing courseware to these systems can therefore be beneficial, sometimes even required. We report here about our experience in migrating an existing courseware system consisting of multimedia content and interactive, integrated infrastructure functionality to an open source course management system called Moodle. We will assess the difficulties that we have encountered during this process and, discuss the importance of standards in this context, and we aim to provide other instructors or instructional designers with guidelines and assessment support for other migration projects

    Using Technology Enabled Qualitative Research to Develop Products for the Social Good, An Overview

    Get PDF
    This paper discusses the potential benefits of the convergence of three recent trends for the design of socially beneficial products and services: the increasing application of qualitative research techniques in a wide range of disciplines, the rapid mainstreaming of social media and mobile technologies, and the emergence of software as a service. Presented is a scenario facilitating the complex data collection, analysis, storage, and reporting required for the qualitative research recommended for the task of designing relevant solutions to address needs of the underserved. A pilot study is used as a basis for describing the infrastructure and services required to realize this scenario. Implications for innovation of enhanced forms of qualitative research are presented

    A schema-based P2P network to enable publish-subscribe for multimedia content in open hypermedia systems

    No full text
    Open Hypermedia Systems (OHS) aim to provide efficient dissemination, adaptation and integration of hyperlinked multimedia resources. Content available in Peer-to-Peer (P2P) networks could add significant value to OHS provided that challenges for efficient discovery and prompt delivery of rich and up-to-date content are successfully addressed. This paper proposes an architecture that enables the operation of OHS over a P2P overlay network of OHS servers based on semantic annotation of (a) peer OHS servers and of (b) multimedia resources that can be obtained through the link services of the OHS. The architecture provides efficient resource discovery. Semantic query-based subscriptions over this P2P network can enable access to up-to-date content, while caching at certain peers enables prompt delivery of multimedia content. Advanced query resolution techniques are employed to match different parts of subscription queries (subqueries). These subscriptions can be shared among different interested peers, thus increasing the efficiency of multimedia content dissemination
