The Semantic Web has the ultimate goal of
making a machine understand Internet data. To enable the encoding of semantics
with the data, well-known technologies are used such as RDF (Resource
Description Framework) and OWL (Web Ontology Language). These technologies
formally represent the meaning involved in information. For example, ontology
can describe concepts, relationships between things, and categories of things.
These embedded semantics offer significant advantages such as reasoning over
data and dealing with heterogeneous data sources.
