Abstract

The Ambient Wood project, carried out as part of the Equator project, set out to provide an augmented learning experience for children in an outdoor environment. Using a variety of devices, the children gathered information about the woodland habitats performing basic scientific enquiry and hypothesis testing. In this paper, we describe the supporting information infrastructure used in the project, focusing on how hypermedia tools and techniques were used to structure and deliver the information to the children, helping to orchestrate the learning activities.

Abstract

Weblogs are gaining momentum as one of most versatile tools for online scholarly communication. Since academic weblogs tend to be used by scholars to position themselves in a disciplinary blogging community, links are essential to their construction. The aim of this article is to analyze the reasons for linking in academic weblogs and to determine how links are used for distribution of information, collaborative construction of knowledge, and construction of the blog's and the blogger's identity. For this purpose I analyzed types of links in 15 academic blogs, considering both sidebar links and in-post links. The results show that links are strategically used by academic bloggers for several purposes, among others to seek their place in a disciplinary community, to engage in hypertext conversations for collaborative construction of knowledge, to organize information in the blog, to publicize their research, to enhance the blog's visibility, and to optimize blog entries and the blog itself.

Abstract

Adaptive Hypermedia has sought to tackle the problems of dealing with complex, heavily structured information and the presentation of views of that structure to users. Increasingly, adaptive content is achieved through different forms of context. Using two case-study applications, we will reflect on how Augmented Reality may present solutions to a number of Adaptive Hypermedia presentation problems. Each case study describes a different physical interaction metaphor for exposing the complex adaptation of hypermedia content in an intuitive way. The preliminary findings of our early evaluations are discussed. Finally, conclusions are drawn as to how Augmented Reality applications could use the modelling techniques of the Adaptive Hypermedia community to deal more easily with complex information.

Abstract

Hypertext ist ein neuartiges Medium des Lesens und Schreibens, das insbesondere die intensive Integration von Text und Bild ermöglicht. Text erhält einen bildlichen Charakter, und Layout und Graphik vermitteln wesentliche Information. Hypertext ist auch interaktiv und unterstützt autonomes Arbeiten und Lernen. Schreiben von Hypertext unterscheidet sich daher stark vom Schreiben linearer Texte. Diese innovativen Eigenschaften machen es oft schwierig, Hypertext in der universitären Lehre einzusetzen. StudentInnen zögern oft, Hypertext zu verwenden, da sie Probleme mit seiner vernetzten Struktur und seinem «bildlichen» Charakter haben. Die Beobachtung des Einführungsprozesses von Hypertext kann Einsichten darüber vermitteln, wie diese Probleme überwunden werden können.

Abstract

We present a general framework for cross-media annotation that can be used to support the many different forms and uses of annotation. Specifically, we discuss the need for digital annotation of printed materials and describe how various technologies for digitally augmented paper can be used in support of work practices. The state of the art in terms of both commercial and research solutions is described in some detail, with an analysis of the extent to which they can support both the writing and reading activities associated with annotation. Our framework is based on an extension of the information server that was developed within the Paper++ project to support enhanced reading. It is capable of handling both formal and informal annotation across printed and digital media, exploiting a range of technologies for information capture and display. A prototype demonstrator application for mammography is presented to illustrate both the functionality of the framework and the status of existing technologies.

Content

This article reports an applied research on the construction and implementation of a semantically structured conceptual prototype to help in the organization and representation of human knowledge in hypertextual systems, based on four references: the Facet Analysis Theory (FAT), the Conceptual Map Theory, semantic structure of hypertext links and the technical guidelines of the Associacao Brasileira de Normas Técnicas (ABNT). This prototype, called Modelo Hipertextual para Organizacao de Documentos (MHTX) - Model For Hypertext Organization of Documents HTXM - is formed by a semantic structure called Conceptual Map (CM) and Expanded Summary (ES), the latter based on the summary of a selected doctoral thesis to which access points were designed. In the future, this prototype maybe used to implement a digital libraty called BTDECI - UFMG (Biblioteca de Teses e Dissertacöes do Programa de Pós-Graduacao da Escola de Ciência da Informacao da UFMG - Library of Theses and Dissertations of the Graduate Program of School of Information Science of Universidade Federal de Minas Gerais).

Abstract

Bei elektronisch vermittelten Kommunikationsprozessen im Kontext von kollaborativem Wissensmanagement in der Lehre entstehen sehr rasch komplexe Kommunikationsstrukturen mit reichhaltigen Verknüpfungen zu heterogenen Informationsmaterialien, die mit herkömmlichen Mitteln zu verfolgen und verfügbar zu machen sehr schnell schwierig bis unmöglich wird. Bisherige Formen von Orientierungshilfe werden eher durch konventionelle Mittel der Kommunikation und Interaktion unterstützt, und daher ist in der Regel kaum nachvollziehbar, wie Wissen, insbesondere dessen repräsentierende Konzepte zusammenhängt, sich entwickelt hat oder wo sich Wissenslücken ergeben. Eine fehlende Orientierung über die Kommunikationsprozesse hat u.a. zur Folge, dass (1) das Angebot elektronischer wissenschaftlicher Information nicht genutzt wird; (2) es zu Orientierungslosigkeit und kognitiven Überlastung kommt und damit die Wissensproduktion gehemmt wird; (3) Wissenslücken nicht aufgezeigt werden und somit in weiteren Diskursen nicht geschlossen werden können; (4) eine Unterstützung für die Moderation fehlt, um effizient Ursachen für Störungen in den Lernprozessen und Konflikten innerhalb der Gruppen zu erkennen; (5) die grundlegende Basis fehlt, um typische Fragen von Benutzern im Umgang mit einem kollaborativen Wissensmanagementsystem in der Lehre effizient beantworten zu können. In der vorliegenden Arbeit wird ein Konzept zur Visualisierung von Kommunikationsstrukturen vorgestellt, das zum Ziel hat, eine effiziente und effektive Orientierungs- und Navigationshilfe für ein kollaboratives Wissensmanagementsystem in der Lehre bereitzustellen. Dabei sollen typische Orientierungsfragen der Benutzer und der Moderation effizient beantwortet werden können. Das entwickelte Gesamtkonzept wurde in das Visualisierungssystem K3Vis umgesetzt und damit dessen Machbarkeit überprüft. K3Vis ist im Forschungsprojekt K3 integriert und steht für den produktiven Einsatz zur Verfügung. K3 steht für Kooperation, Kommunikation und InformationsKompetenz und ist ein von der Konstanzer Informationswissenschaft initiiertes Projekt im Kontext des kollaborativen Wissensmanagements in der Lehre. Im Rahmen dieser Arbeit wurden alle historischen, von den Studierenden kollaborativ erarbeiteten Arbeitsaufträge im Detail analysiert und dabei symptomatische Muster in Kommunikationsstrukturen ermittelt, die bei der Bewertung und der Moderation des Diskursverlaufs hilfreich sein können. An konkreten, "produktiven" Beispielen werden diese Diagnosemöglichkeiten anhand von Abbildungen diskutiert.
