THE VISUALISATION AND EXPLORATION OF A CURRICULUM KNOWLEDGEBASE

Sebastian Richards, Hilary Dexter

Abstract

This paper discusses the difficulties associated with the visualisation and navigation of complex, multi-faceted knowledgebases. The issues are analysed through a case study of the Manchester Medical School curriculum, with the intention of developing an innovative visualisation tool to enhance the experience of navigation through such large sets of data. The approach taken to provide a solution involves the use of a metaphorical representation of the data schema, designed to reduce visual complexity and increase human usability. User feedback uncovered the need to create a ‘trail’ of related concepts through the knowledgebase, and provision for such navigation techniques is present in the developed tool. The concept of domain-specific structural customisation was investigated and led to the suggestion that modification of a schema towards a more logical and human-friendly abstraction can improve a user’s understanding and engagement with data.
