    Adaptive features of a hypermedia system using bookmark per Web page
    (13. GI-Workshop "Adapitivität und Benutzermodellierung in interaktiven Softwaresystemen", 2005) Jung, Hyosook; Park, Seongbin
    In this paper, we present a technique called bookmark per Web page by which users can build a new link structure in a hypermedia. It allows users to create their own links for Web pages. Our aim is to provide an adaptive hypermedia with additional adaptive features by considering properties which the author of the hyperspace did not provide when the hyperspace was designed. In addition, a general hypermedia that does not have adaptive features can support personalized views of hyperdocuments using this technique. We expect that the bookmark per Web page can enhance information accessibility and reduce navigation disorientation and cognitive overload. We implemented our technique by modifying AHA![De Bra et al., 2003] which is an open source adaptive hypermedia system. We developed Java servlets and included them in the adaptation engine of AHA!. We added a link at- tribute for each concept at the user profile and assigned URL addresses of new links for its values.

    Enhancing adaptive capabilities of an adaptive hypermedia system
    (13. GI-Workshop "Adapitivität und Benutzermodellierung in interaktiven Softwaresystemen", 2005) Jung, Hyosook; Park, Seongbin
    In a complex hyperspace, people may experience the problems of disorientation and cognitive overload[Conklin, 1987] and to overcome these problems, adaptive hypermedia technologies provide personalized information to learners with different learning paces, abilities, interests, etc[De Bra et al., 1999]. However, it is difficult to predict complex situations that could arise during navigation in an adaptive hypermedia in advance. For example, users may want to extend the con- tents of an adaptive hypermedia when they find some information using a search engine. In this paper, we propose an approach by which adaptive capabilities of an exiting adaptive hypermedia such as adapting according to changes of a domain model or a user model can be enhanced.

    A JXTA-based music information retrieval system
    (Information Systems Technology and its Applications, 5th International Conference ISTA 2006, 2006) Jung, Hyosook; Park, Seongbin
    In this paper, we present a JXTA-based system for contents-based music information retrieval. The system finds matching melodies from a set of XML documents that encode music contents. The XML documents are stored in a native XML database and XPath query language is used to extract the information about the structure of music data. The matching algorithm utilizes the geometric hashing technique [Wo97] by analyzing geometric properties of both XML documents and music contents. The system preprocesses extracted music contents and stores the information about melody patterns in a relational database. When a user sends a query about a melody, it searches melody patterns that have similar geometric properties as the query melody.

    A JXTA-based system for adaptive and collaborative learning
    (10th International Conferenceon Innovative Internet Community Systems (I2CS) – Jubilee Edition 2010 –, 2010) Jung, Hyosook; Ahn, Jinhyun; Park, Seongbin
    In this paper, we present an adaptive and collaborative learning system that is based on JXTA technology [jx205, Gon01]. JXTA enables any connected devices in a network to participate in communication and collaboration as peers and our system supports additional functionalities such as adaptive navigation, adaptive group formation, and instant messaging. We tested our system against undergraduate students who took a data structure class. The experimental results indicate that our JXTA-based learning system helped students learn effectively.
