Where are the Semantics in the Semantic Web?
Introduction
The current evolution of the Web can be characterized from various perspectives [Jasper & Uschold 2001]:
Locating Resources: The way people find things on the Web is evolving from simple free text and keyword search to more sophisticated semantic techniques both for search and navigation.
Users: Web resources are evolving from being primarily intended for human consumption to being intended for use both by humans and machines .
Web Tasks and Services: The Web is evolving from being primarily a place to find things to being a place to do things as well [Smith 2001].
All of these new capabilities for the Web depend in a fundamental way on the idea of semantics. This gives rise to a fourth perspective along which the Web evolution may be viewed:
- Semantics—The Web is evolving from containing information resources that have little or no explicit semantics to having a rich semantic infrastructure.
