  1. BTW Information Annotation By Rudd Stevens, Jason Endo

  2. Introduction • Current methods of sharing knowledge between users: Blogs, email, bulletin boards, instant messaging, websites. • All require users to know contact information for sharing data and knowledge.

  3. Problem Statement • We would like to connect objects and users easily and intuitively on the web, without knowing contact information. • Objects would represent collections of information, people, institutions, journals, books, etc. • A web based solution would be ideal because it’s platform independent.

  4. Potential Solution • Create web related interface (web browser plug-in) for exchanging information between users. • Auto generated linking system provides notification tag for user’s web page. • Central server for storing nuggets and servicing requests.

  5. What is a nugget? • An “object” representing some entity. • The entity could be a person, paper, book, conference or film, etc. • The nugget could be a short biography note on a person, a comment on an article or a snippet of code describing a concept. • The information is encoded via RDF to provide commonality and persistance.

  6. Persistence • Use RDF schema to store nuggets on local machine, as well as a central server. • Provides ease of data handling and modification. • Different models of RDF schemas may be applicable, or a combination of schemas could be used. • Dublincore most likely candidate.

  7. Request for web page Web page with HTML ID tag Nugget Source Client HTML ID tag Submit nugget to server Return list of nuggets Server Structure/Operation

  8. Additional Features • Referral system for users that reflects knowledge about topic areas. • Search interface for database, allow creation and viewing of nuggets not linked to a website. • Link nuggets to other nuggets by context and content. • Random nugget, new nuggets, similar nuggets abilities.
