Problem statement: knowledge life-cycle

Corporate memory today© Peter Demian, Renate Fruchter 2001
Corporate memory today© Peter Demian, Renate Fruchter 2001
Information overload?• A small corporate memory:
• 10 projects• 10 disciplines• 100 components• 100 versions
106 items
© Peter Demian, Renate Fruchter 2001
Corporate memory:
A repository of knowledge in context
Knowledge in context:
Knowledge captured and presented in the context in which it was created, e.g.:
• rationale• evolution• project environment• multidisciplinary perspectives

Colors
Similarity Cumulative similarity Averaged similarity
© Peter Demian, Renate Fruchter 2001
Other issues• Ordering (proximity between similar siblings)
• Labels (needed?)
• Small trees (or small branching factor)
• Beyond trees (mutli-trees, graphs)
• Focal point(s)? (filtering, zooming, distortion)
• Emphasis? (filtering, zooming, distortion)
© Peter Demian, Renate Fruchter 2001
If a treemap is the solution, then what is the problem?
• Visualization, in general:• Beyond information (document) retrieval• Exploration, c.f. creativity
• Specifically treemaps:• Multiple levels of granularity • Large data, small area
