Based on an analysis of existing tools and approaches and literature from the areas of design and cognitive science, we identify a set of functional requirements to be met by diagrammatic knowledge mapping techniques and tools in order to be cognitively adequate for extensive personal knowledge...

We present iMapping, a diagrammatic zooming and nesting based approach for visually structuring information objects on the desktop with a special focus on personal knowledge management. It was designed based on a set of requirements gathered from the analysis of existing knowledge mapping...

This thesis describes iMapping and QuiKey, two novel user interface concepts for dealing with structured information. iMapping is a visual knowledge mapping technique based on zooming, which combines the advantages of several existing approaches and scales up to very large maps. QuiKey is a...

Purpose – The purpose of the paper is to design a model and tools that are capable of representing and handling personal knowledge in different degrees of structuredness and formalisation, and usable and extensible by end‐users. Design/methodology/approach – This paper presents the results...
