BTW Information Annotation By Rudd Stevens, Jason Endo
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.
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.
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.
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.
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.
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
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.
