DNP (dai nippon printing co) project Magitti:

19-25 years have twice as much free time as other youth !
-local and localized info
- want to know what others think

User mobile with GPS: keeps on reading user presence info:

- Match in DB, present a list of possible activities

- Predict activity
- Location, preferences etc

DB: Activity - Venue - Weight
EAT straits cafe 0.77
Weighted according to user's preferences

Twine presentation

Share knowledge / interests
knowledge management...
built on w3c standards (offshoot of calo project)

Person's twine: shared with different groups
ontology...

individuals and groups (twines) have email addresses

"Database , merged with a wiki"
new fields can be added by user
Semantic graph... every object has a type in graph : e.g. book, friend...
- figure out how connected I am to that object
- e.g. based upon interests, recommendations from trusted people

Automatic research in background finding matching stuff for me...
- can even disagree with individual's tag / recommendations !?
