    Indexing of fictional video content for event detection and summarisation

    This paper presents an approach to movie video indexing that utilises audiovisual analysis to detect important and meaningful temporal video segments, that we term events. We consider three event classes, corresponding to dialogues, action sequences, and montages, where the latter also includes musical sequences. These three event classes are intuitive for a viewer to understand and recognise whilst accounting for over 90% of the content of most movies. To detect events we leverage traditional filmmaking principles and map these to a set of computable low-level audiovisual features. Finite state machines (FSMs) are used to detect when temporal sequences of specific features occur. A set of heuristics, again inspired by filmmaking conventions, are then applied to the output of multiple FSMs to detect the required events. A movie search system, named MovieBrowser, built upon this approach is also described. The overall approach is evaluated against a ground truth of over twenty-three hours of movie content drawn from various genres and consistently obtains high precision and recall for all event classes. A user experiment designed to evaluate the usefulness of an event-based structure for both searching and browsing movie archives is also described and the results indicate the usefulness of the proposed approach

    How Sustainable are Benefits from Global Production Networks? Malaysia's Upgrading Prospects in the Electronics Industry

    Get PDF
    The paper introduces an operational definition of industrial upgrading (IU and documents the emergence of complex, multi-tier "networks of networks" which provide new opportunities for IU, but which also raise threshold requirements for participating in these networks. I highlight structural weaknesses of the Malaysian electronics industry that constrain its upgrading prospects; assess current policies that try to link cluster development and global network integration; discuss adjustments in linkages with global brand leaders (OEMs); and ask to what degree linkages with contract manufacturers (CMs) can broaden network benefits. The paper concludes, by exploring new opportunities for international knowledge sourcing that could complement Malaysia's linkages with GPNs. A completely revised and updated version has been published as: "Global Production Networks and Industrial Upgrading -Malaysia's Electronics Industry", in: J. Kidd and F.J. Richter, eds., Trust and Anti-Trust in Cross-Cultural Alliances, published for the World Economic Forum, Palgrave, London, 2003.

    Overview of Digital Library Components and Developments

    Get PDF
    Digital libraries are being built upon a firm foundation of prior work as the high-end information systems of the future. A component architecture approach is becoming popular, with well established support for key components like the repository, especially through the Open Archives Initiative. We consider digital objects, metadata, harvesting, indexing, searching, browsing, rights management, linking, and powerful interfaces. Flexible interaction will be possible through a variety of architectures, using buses, agents, and other technologies. The field as a whole is undergoing rapid growth, supported by advances in storage, processing, networking, algorithms, and interaction. There are many initiatives and developments, including those supporting education, and these will certainly be of benefit in Latin America

    Management Information Systems Research: What’s There in a Methodology?

    Get PDF
    Management information systems (MIS) is both a young and unique field, constantly experiencing rapid change and turmoil. Consequently, MIS research faces dual changes of rigor and relevance. Many research methodologies exist that provide various combinations of rigor and relevance. The MIS researcher selects a methodology based on several factors including rigor, relevance, subject area, and personal preferences. In this article, we examine thirteen different methodologies as used by seven leading MIS journals during a recent five-year period. The results of this extensive analysis yielded some interesting results. Survey methodology consistently ranks at the top; while frameworks and conceptual models, lab experiments, and case studies also found significant use among the MIS community. Several trends were observed, one of them being a greater use of the case study method and other qualitative technologies over the years. Clear patterns also emerged based on the journal itself and the subject areas. At a macro level, this information should help authors in the choice of appropriate methodologies to use in specific subject areas and in targeting manuscripts to appropriate journals. It would also be helpful to journal editors in assessing the type of research and methods being used across journals and subjects, and whether they need to make any changes in the emphases of their own journals

    Leveraging Multimedia to Advance Science by Disseminating a Greater Variety of Scholarly Contributions in More Accessible Formats

    For the welfare of the scientific community, we intentionally “rock the boat” about the way we conduct, recognize, and disseminate scholarly contributions. As a scientific community, we are doing ourselves a great disservice by ignoring the insights, artifacts, discoveries, and conversations that naturally occur in the scientific process of advancing knowledge that do not fit into the narrowly defined form of print-style papers. By failing to recognize, reward, and publish the wide variety of scholarly contributions that do not suit print-style papers, we hinder scientific progress, devalue important and necessary contributions to science, and demotivate these types of vital contributions. Although over three centuries of scientific publishing has demonstrated the effectiveness of the print medium for conveying scholarly knowledge, the print-style paper captures only a single form of scholarly contribution in a highly limited media format. Unfortunately, the current tenure and promotion process recognizes only this one form of scientific contribution. As a result, science at large advances inevitably only by this single type of contribution. Given the radical advances in audiovisual technologies, storage and bandwidth capacities, public virtual infrastructure, and global acceptance of user-generated open content, the time is ripe to exploit the possibility of publishing more forms of scholarly contributions in a publicly available multimedia format (e.g., video). In this paper, we examine the feasibility of this proposal, develop a model to demonstrate the sustainability of this approach, and discuss potential limitations
