Visualisation in the NATO/RSG-30 conext.
Questions: Where are we going? Why haven't we achieved anything? Is our focus right?
The challenge: to reach the next level of visualisation
But: what is this 'next level' and how do we achieve it?
Review of tasks:
1. survey/database ö what is the role of the strawman document?
2. datasets v problems sets ö which is the right medium? or
do we need both?
Bottom line: without regard to cognition and human factors we will fail.
Task is vast and requires decomposition. The analysis of different media requires common formats. These are knowlegde elements. To acquire knowledge elements different media need to be assimilated to form these knowledge elements. Inorder to gain knowledge from a collection of knowledge elements, some kind of dissemination must take place. KH's view was that the hard parts were the construction and dissemination of the knowledge not the representation of it.
Questioned whether we have the correct skill set.
Sited librarians and information scientists as having the correct skills. These people collate information, index it and then disseminate it.
Wished that the focus could revert to text based as he perceives that converting text into a useful product is a hard problem.
Wished for the inclusion of knowledge extraction from images
Asked what visualisation meant. What about useability for non-expert users? What are the right questions
Emphasised that in her view representational issues were secondary and that the real problem was the transition from raw data to knowledge elements.
Disagreed with KH. In her view the representational issues where not yet solved and this should be the primary focus of the group.
