    Where are your Manners? Sharing Best Community Practices in the Web 2.0

    The Web 2.0 fosters the creation of communities by offering users a wide array of social software tools. While the success of these tools is based on their ability to support different interaction patterns among users by imposing as few limitations as possible, the communities they support are not free of rules (just think about the posting rules in a community forum or the editing rules in a thematic wiki). In this paper we propose a framework for the sharing of best community practices in the form of a (potentially rule-based) annotation layer that can be integrated with existing Web 2.0 community tools (with specific focus on wikis). This solution is characterized by minimal intrusiveness and plays nicely within the open spirit of the Web 2.0 by providing users with behavioral hints rather than by enforcing the strict adherence to a set of rules.Comment: ACM symposium on Applied Computing, Honolulu : \'Etats-Unis d'Am\'erique (2009

    Extending the 5S Framework of Digital Libraries to support Complex Objects, Superimposed Information, and Content-Based Image Retrieval Services

    Get PDF
    Advanced services in digital libraries (DLs) have been developed and widely used to address the required capabilities of an assortment of systems as DLs expand into diverse application domains. These systems may require support for images (e.g., Content-Based Image Retrieval), Complex (information) Objects, and use of content at fine grain (e.g., Superimposed Information). Due to the lack of consensus on precise theoretical definitions for those services, implementation efforts often involve ad hoc development, leading to duplication and interoperability problems. This article presents a methodology to address those problems by extending a precisely specified minimal digital library (in the 5S framework) with formal definitions of aforementioned services. The theoretical extensions of digital library functionality presented here are reinforced with practical case studies as well as scenarios for the individual and integrative use of services to balance theory and practice. This methodology has implications that other advanced services can be continuously integrated into our current extended framework whenever they are identified. The theoretical definitions and case study we present may impact future development efforts and a wide range of digital library researchers, designers, and developers

    This paper presents an approach combining concepts of virtual storytelling with cooperative processes. We will describe why storytelling is relevant in cooperation support applications. We will outline how storytelling concepts provide a new quality for groupware applications. Different prototypes illustrate a combination of a groupware application with various storytelling components in a Theatre of Work

    The iPhone is a line of Internet- and multimedia-enabled smartphones designed and marketed by Apple Inc. The first iPhone was unveiled by Apple CEO Steve Jobs on January 9, 2007, and released on June 29, 2007. An iPhone can function as a video camera (video recording was not a standard feature until the iPhone 3GS was released), a camera phone, can send texts and receive visual voicemail, a portable media player, and an Internet client with email and web browsing capabilities, and both Wi-Fi and 3G connectivity. The user interface is built around the device's multi-touch screen, including a virtual keyboard rather than a physical one. Third-party as well as Apple application software is available from the App Store, which launched in mid-2008 and now has over 350,000 "apps" approved by Apple. These apps have diverse functionalities, including games, reference, GPS navigation, social networking, e-booksEscuela Técnica Superior de Ingeniería de TelecomunicaciónUniversidad Politécnica de Cartagen

    An Application Framework for Distributed Multimedia System Development

    Get PDF
    [[abstract]]In this paper, a distributed multimedia application framework is proposed. The framework is based on Model-View-Controller of Smalltalk-80. Multimedia applications are developing as a popular. However, development of highly interactive multimedia applications for today’s high-powered computer is complex and time consuming. An application framework is typically composed of mixture of abstract and concrete classes along with a model of interaction and control flow among the classes. The application framework has “hooks” to allow an application programmer to plug in objects that represent the functionality unique to this application. The distributed processing of multimedia information enables advanced application areas like video conferencing, video on demand and improves the performance in other areas. Thus, it is necessary that an application framework be built for distributed multimedia.[[notice]]補正完

    Multimedia presentation design using data flow diagrams

    Get PDF
    [[abstract]]Structured analysis/design methodology has been used in software development for many years. We propose a revised data flow diagram technique and system based on the structured analysis methodology. The system allows a multimedia presentation designer to stepwise refine his/her presentation toward an interactive Petri net, which defines the temporal behaviour of the presentation. The generated presentation can mutate itself at runtime. Therefore, the presentation can act according to the audience's responses. The system is implemented in Visual C++ and Visual Basic running under Windows 95/NT[[conferencetype]]國際[[conferencedate]]19971028~19971031[[iscallforpapers]]Y[[conferencelocation]]Beijing, Chin
