The Semantic Web: Managing Knowledge for Planet Earth

Pat Hayes
Senior Research Scientist
Institute for Human and Machine Cognition

Abstract

The Semantic Web (SWeb) is a vision - actually, a number of visions - which is beginning to show some signs of potential reality. The core of the vision is a synergy between machine-accessible knowledge and the global reach of the Web. The deployment of knowledge technologies on a planet-wide open network brings new challenges and opportunities, many of them not yet fully realized. This talk briefly surveys the current state of play in SWeb standards and technology, including some of the rather heated controversies, and tries to give a high-level view of some of these challenges and opportunities. Some traditional hard problems in KM may largely evaporate; but new ones will take their place.

Biography

Pat Hayes received a BA in mathematics from Cambridge University and a PhD in Artificial Intelligence from Edinburgh. He has held academic positions in computer science at the University of Essex (England), in philosophy at the University of Illinois and as the Luce Professor of cognitive science at the University of Rochester.
