“…A context is prominent notion that surfaces across different academic domains, from psychology and cognitive science to HCI and system engineering. Akaishi et al (2003) define it as a modular representation of information under different perspectives in their description of a framework for context-based generation of information access spaces. Same notion is repeated in the work of Theodorakis et al (2002) who define context as a cognitive container which encapsulates a particular information view.…”

Abstract:The emergence of the Web 2.0 technologies in the last years have changed the way people interact with knowledge. Services for cooperation and collaboration have placed the user in the centre of a new knowledge building space. The development of new second generation learning environments can benefit from the potential of these Web 2.0 services when applied to an educational context. We propose a methodology for designing learning environments that relates Web 2.0 services with the functional requirements of these environments. In particular, we concentrate on the design of the KRSM system to discuss the components of this methodology and its application.

“…However, the axes which are the basis for organization have a one-toone relationship with each attribute in the frame and therefore a single axis cannot be defined using multiple attributes. In prior research as well [10], only views using a single specified attribute value could be defined. With this research, it becomes possible to define frames of reference using multiple attribute values of a record.…”

“…The user navigates through the virtual space, which has a spatial structure based on data structures such as a hierarchical structure [5][6][7] or the ODB (objectoriented database) nested structure [8,9], and accesses information. In CIAS [10] as well, a contextual model [11] is applied to a database to provide a hyperlinked structure and an information access space is created by mapping this © 2006 Wiley Periodicals, Inc.…”

“…A user can thereby repeat spatial movements while dynamically modifying his frame of reference, make walking searches across multiple tables, and arrive at the desired data while gradually narrowing his focus based thereon. This paper demonstrates a prototype based on three-dimensional componentware architecture and the possibility of realizing the proposed concept of facets, extending the CIAS [10] mechanism. Because this system provides facets as three-dimensional visualization components which can be directly manipulated, the user can manipulate these components and introduce and edit frames of reference.…”

SUMMARYIn order to access target information while getting an overview of the entirety of a large-scale database, a search must be carried out in parallel with various modifications to the frame of reference and dynamic organization of the information. In this research, this type of database search is realized through an information access space dynamically constructed of hyperlinks based on an arbitrary frame of reference. The authors propose a new concept and structure for the frames of reference and develop a mechanism for dynamically linking individual database records with multiple information access spaces, dynamically constructed on the basis of declarative definitions of these frames of reference. The authors also provide a three-dimensional interface for editing frames of reference and for spatial navigation threaded by these links. These operations correspond to query processing by narrowing down the subject tables and joining multiple tables; the user can gradually narrow his focus and arrive at the target information by dynamically modifying his frame of reference and repeating spatial movements. In this paper, a three-dimensional interface is developed and database searches using that interface are evaluated; it is shown that this technique makes it possible to quickly access target information.
