Note: in 1995, there were ~16,000,000 Internet users, or 0.4% of global population

(see also: Top languages on the Internet [graphic, link],
English 30% w/ 125% growth, Chinese 14% w/ 347% growth per year)

Web Accessibility @ W3C

Leading Edge: Web on Everything

Vision: Web on Everything

One Web ...
... where Web technologies provide the means of accessing and interacting with content via all devices, including computing, communications, entertainment, embedded, personal, home, transportation, industrial, health care, etc. systems
... worldwide.

Why Does a Web on "Everything" Make Sense?

Underachieving Today. Hope for Tomorrow.

  • There is hope - when the user experience is good, consistent, etc.

Why Do We Need the Semantic Web?

Why Can't Computers "Understand"?

What Computers "Understand"

Toward Processable Search Semantics

What if Web pages had more semantics?

Ways to Enable Machine Processing

Smarter Machines

Smarter Data

Semantic Web: Data on the Web

Tim's Semantic Web Stack (2005) Machine-processable, global Web standards:
  • Assigning unambiguous names (URI)
  • Expressing data, including metadata (RDF)
  • Capturing ontologies (OWL)
  • Query, rules, logic, proofs, trust (in progress)

Heart of the Semantic Web

RDF as circles and arrows

Most of the Current Web

Old Web - Linking resources

Semantic Web: "Smarter" Resources and Links

Semantic Web - Undertstandable relationships between undertandable resources


[ellipses = resources; color = one data source; x: = one ontology]

(see also more detailed example related to book searching and selling)

Enterprise Integration Today

Enterprise intergration pre-RDF

Enterprise Integration on the "RDF Bus"

Enterprise intergration using RDF

Clients on the "RDF Bus"

New data applications can be built on top of RDF bus, for example:

Timing Strawman

Killer apps (or even failures) could radically change the timeline.
