around the web of personal information

3. Outline
A Survey:
● Brief view of existing systems
● Design implications
from studies of information organization systems
● Future work

4. Existing systems
That have characteristics of my ideal system
 Padprints
 Footprints
 WebForager, WebBook
 DataMountain
 ScratchPad
 InsightFinder

12. InsightFinder
Context based recommendation

web-based sensemaking tasks

14. Design implications
 Visibility (and reminding)
 Integration with existing work-flow
 Co-Adoption (affordance for people who work as a group to adopt the
system)
 Scalability (with respect to the type or amount of information that the
user wants to process)
 Return on Investment

Abandonment of Information Management Strategies

15. Future work
Associate information scents with resources indicating:
1. The cost of foraging a resource
URLs, for example
2. The chances that it will be eventually used as intended
Bookmarks, for example
 based on your history with other pieces of similar information
 based on the information's history with other similar people
Prevent us from becoming information gluttons !

18. Spatial memory
Clark's nutcracker :
 buries 30k seeds across an area of 100 sq.miles
 places a stone on top of the stash
 recovers 70% of the nuts buried under several feet
of snow
 278+ days
 But human spatial memory is limited to around 10
objects and suitable only for short-term
