Two Years before the Mist: Experiences with Aquanet

Aquanet is a collaborative hypertext tool that combines elements of frame-based knowledge representation and graphical presentation. In this paper, we examine the first major application of the tool in an analysis task, a two year long technology assessment that resulted in almost 2000 nodes and more than 20 representational types. First, we cover the implications of the representational resources provided and representational decisions that were made. Then we discuss how spatial layout was used in lieu of the complex relations Aquanet's data model supports. Finally, we show how distinct regions emerged to reflect particular activities and how they were subsequently used as the basis for a later collaboration on a similar task. 1 Overview: The tool and the task Aquanet is a collaborative hypertext tool designed to meet the needs of knowledge structuring tasks like analysis and argumentation. The tool combines elements of frame-based knowledge representation and graphical presenta...
