11. information-rich visualizations
Pampelk ref - SOM maps –self-organizing map (using neural net) (millions of docs; system automatically creates the map; search on finnish demo)
labels are core vocabulary of map unit docs
coloring – light are more dense (clusters) and dark are ravines between clusters

12. information-rich visualizations
Pampalk et al - 6 Mozart sonatas by 6 famous pianists – idea is to allow user to adjust variables and analysis method
also Islands of Music (music repositories) and animals (characteristics like appearance vs. activity)

13. evaluating data
Gresh et al – Figure 7 -
shows how user can manipulate information and examine outliers (potential money losers or makers)

14. 3D
Periscope project – search results - website at:
demo (test):
Compare search results
- cylinders are domains (green bar if subdomains)
- documents (circles on host; squares if doc on subdomain host)
- move cylinders around
