particularly for scientific applications. Deborah is a leader in ontology-based tools and applications. She also consulted to help VerticalNet design and build its Ontobuilder/Ontoserver ontology evolution environment. She also provided technical leadership for the Stanford project to help Cisco systems form its ontology evolution plan for its meta data formation work.

Who we are Dr. Deborah McGuinness is the acting director and senior

research scientist at the Knowledge Systems, (KSL) Artificial Intelligence Laboratory at Stanford University. She is a leading expert in knowledge representation and reasoning languages and systems and has worked in ontology creation and evolution environments for over 20 years. Most recently, Deborah is best known for her leadership role in semantic web research, and for her work on explanation, trust, and applications of semantic web technology,

Semantic Web

Key "next generation" evolution of the Web Languages at maturity

RDF, RDFS, OWL all W3C recommendations

SPARQL in CR Support growing

Major vendors playing (Adobe, Oracle, …)

Startups in Web 3.0 space (Metaweb, RadarNetworks, …)

Lots of open source tools

Moving Beyond Semantic Web

The Web has been transformational Largest human information construct

A "science" that takes the Web as a primary area of interest Understand what it is Engineer its future

Semantic Web is an example Ensure its social benefit

This requires a new interdisciplinary effort Computer Science Cognitive Science Social/Policy issues

World

Web Evolution

World

A "Systems" Science

The Web is so complex it needs its own Systems Science Inspiration from new

formal models

Understanding of "Scaling" How does the "miracle"

happen

World

New Engineering

The Web needs new engineering standards, methods and tools Access to data globally Decentralization for

resilience Radical

decentralization made the Web work How do we make that

happen in new and emerging areas

World

New Social Models

The Web is essentially social And getting moreso

The Web has huge impact on society Information access and

use Privacy issues Information flow control

Example: Policy Aware Web(NSF ITR; Hendler, Berners-Lee, Weitzner; 2005)

Potentially disruptive social technology Build, but also understand early…

What we need to understand

The features that make the web work The threats of fragmentation The macro from the micro How to incorporate semantics How to exploit statistics How to build services How to instill trust, resilience and

dependability

World

Constellation Goal

The pervasive, mobile and ubiquitous Web, requires: Aka "Tetherless"

Understanding the Web as a network at all scales From protocol to social network levels Non-browser access issues (above the IP level)

Policy Aware Computing End to end semantic accountability

New methods for Privacy protection Security needs Intellectual property rights (and wrongs)
