OWL语言初步介绍
The OWL Web Ontology Language is an international standard for
encoding and exchanging ontologies and is designed to support the Semantic
Web. The concept of the Semantic Web is that information should be given
explicit meaning, so that machines can process it more intelligently. Instead
of just creating standard terms for concepts as is done in XML, the Semantic
Web also allows users to provide formal definitions for the standard terms
they create. Machines can then use inference algorithms to reason about the
terms. For example, a semantic web search engine may conclude that a
particular CD-read/write drive matches a query for “Storage Devices under
$100.” Furthermore, if two different sets of terms are in turn defined using a
third set of common terms, then it is possible to automatically perform
(partial) translations between them. It is envisioned that the Semantic Web
will enable more intelligent search, electronic personal assistants, more
efficient e-commerce, and coordination of heterogeneous embedded systems.
