Web Based Training Systems and Document Annotation – Implementations for Hyperwave

Web Based Training Systems are the result of a number of developments in different disciplines of computer science in recent years. These developments include Computer Aided Instruction, Hypertext and Hypermedia, and the World Wide Web. This thesis describes these developments and how they are brought together in Web Based Training Systems. It gives an overview over existing Web Based Training Systems including the Hyperwave-based system GENTLE currently developed at the Institute for Information Processing and Computer Supported New Media at the Graz University of Technology. One special aspect of Web Based Training Systems – document annotation – is discussed in detail, and three implementations of document annotation based on Hyperwave are illustrated. I hereby certify that the work reported in this thesis is my own and that work performed by others is appropriately cited. Signature of the author: __________________________________________
