Stanford Meet-up Summary

http://tw.rpi.edu/wiki09

• 12 attendees, 3.5 hours • 4 Talks

– Halo Extension, by Mark Greaves.

– Wikidsmart Demo, by Sanjiva Nath • http://www.zagile.com/products/wikidsmart.html

– From SMW to rule, by Jie Bao

– SMW based Web Application Model, by Li Ding.

• In-depth discussion on a couple of topics– Integrity checking, template-based UI, privacy, SMW for business use

(e.g. spreadsheet)

• Partially recorded (will be available after cleaning up)

04/21/23 12

Plan

• Development– SMW based light-weight group/project portal– SMW Best practices

• Research (in 3-6 month)– SMW syntax and query formalization– Rule modeling on SMW– Semantic Wiki based web application model– Semantic History

04/21/23 13

Future Directions

• Collaborative Data Sharing Platform– Semantic access control at finer granularity– Convergence of knowledge– Effective UI to generate and browse data

• Distributed Data– Distributed query– Portable/permanent Semantic Web data– Ontology mapping, entity mapping, and linked data

• Large Scale Data– Response time: read, write, query, and inference– Space: temporary table, network traffic, …
