    CHORUS Deliverable 2.2: Second report - identification of multi-disciplinary key issues for gap analysis toward EU multimedia search engines roadmap

    After addressing the state-of-the-art during the first year of Chorus and establishing the existing landscape in multimedia search engines, we have identified and analyzed gaps within European research effort during our second year. In this period we focused on three directions, notably technological issues, user-centred issues and use-cases and socio- economic and legal aspects. These were assessed by two central studies: firstly, a concerted vision of functional breakdown of generic multimedia search engine, and secondly, a representative use-cases descriptions with the related discussion on requirement for technological challenges. Both studies have been carried out in cooperation and consultation with the community at large through EC concertation meetings (multimedia search engines cluster), several meetings with our Think-Tank, presentations in international conferences, and surveys addressed to EU projects coordinators as well as National initiatives coordinators. Based on the obtained feedback we identified two types of gaps, namely core technological gaps that involve research challenges, and “enablers”, which are not necessarily technical research challenges, but have impact on innovation progress. New socio-economic trends are presented as well as emerging legal challenges

    Easy designing steps of a local data warehouse for possible analytical data processing

    Data warehouse (DW) are used in local or global level as per usages. Most of the DW was designed for online purposes targeting the multinational firms. Majority of local firms directly purchase such readymade DW applications for their usages. Customization, maintenance and enhancement are very costly for them. To provide fruitful e-services, the Government departments, academic Institutes, firms, Telemedicine firms etc. need a DW of themselves. Lack of electricity and internet facilities, especially in rural areas, does not motivate citizen to use the benefits of e-services. In this digital world, every local firm is interested in having their DW that may support strategic and decision making for the business. This study highlights the basic technical designing steps of a local DW. It gives several possible solutions that may arise during the design of the process of Extraction Transformation and Loading (ETL). It gives detail steps to develop the dimension table, fact table and loading data. Data analytics normally answers business questions and suggest future solutions

    Harnessing Collaborative Technologies: Helping Funders Work Together Better

    This report was produced through a joint research project of the Monitor Institute and the Foundation Center. The research included an extensive literature review on collaboration in philanthropy, detailed analysis of trends from a recent Foundation Center survey of the largest U.S. foundations, interviews with 37 leading philanthropy professionals and technology experts, and a review of over 170 online tools.The report is a story about how new tools are changing the way funders collaborate. It includes three primary sections: an introduction to emerging technologies and the changing context for philanthropic collaboration; an overview of collaborative needs and tools; and recommendations for improving the collaborative technology landscapeA "Key Findings" executive summary serves as a companion piece to this full report

    CHORUS Deliverable 2.1: State of the Art on Multimedia Search Engines

    Get PDF
    Based on the information provided by European projects and national initiatives related to multimedia search as well as domains experts that participated in the CHORUS Think-thanks and workshops, this document reports on the state of the art related to multimedia content search from, a technical, and socio-economic perspective. The technical perspective includes an up to date view on content based indexing and retrieval technologies, multimedia search in the context of mobile devices and peer-to-peer networks, and an overview of current evaluation and benchmark inititiatives to measure the performance of multimedia search engines. From a socio-economic perspective we inventorize the impact and legal consequences of these technical advances and point out future directions of research

    Building Scalable Communities from International Knowledge Networks

    Get PDF
    Small organizations frequently implement knowledge networks where people use their personal uncoordinated connections to transfer information. Although small knowledge networks may be very effective, they often experience problems as they grow. One way organizations can counteract this is by developing communities of practice. Cycling Without Age (CWA) is an organization that faces issues with knowledge sharing due to a rapidly expanding network. The goal of this project was to help CWA develop a community of practice that allows for more effective knowledge transfer. We investigated CWA’s knowledge network structure and analyzed their social learning group behavior in order to develop a governance structure around the network and implement a new platform

    Teaching and learning in virtual worlds: is it worth the effort?

    Get PDF
    Educators have been quick to spot the enormous potential afforded by virtual worlds for situated and authentic learning, practising tasks with potentially serious consequences in the real world and for bringing geographically dispersed faculty and students together in the same space (Gee, 2007; Johnson and Levine, 2008). Though this potential has largely been realised, it generally isn’t without cost in terms of lack of institutional buy-in, steep learning curves for all participants, and lack of a sound theoretical framework to support learning activities (Campbell, 2009; Cheal, 2007; Kluge & Riley, 2008). This symposium will explore the affordances and issues associated with teaching and learning in virtual worlds, all the time considering the question: is it worth the effort

    Transforming pre-service teacher curriculum: observation through a TPACK lens

    Get PDF
    This paper will discuss an international online collaborative learning experience through the lens of the Technological Pedagogical Content Knowledge (TPACK) framework. The teacher knowledge required to effectively provide transformative learning experiences for 21st century learners in a digital world is complex, situated and changing. The discussion looks beyond the opportunity for knowledge development of content, pedagogy and technology as components of TPACK towards the interaction between those three components. Implications for practice are also discussed. In today’s technology infused classrooms it is within the realms of teacher educators, practising teaching and pre-service teachers explore and address effective practices using technology to enhance learning
