In this chapter, we give some background on the Semantic Web, ontologies, and the
valuable sources of Web information available for e-business applications. We then
describe how textual information can be extracted to produce XML files automatically.
Finally, we discuss future trends for this research and conclude.
Background
The World Wide Web Consortium (W3C) is leading efforts to standardize languages
for knowledge representation on the Semantic Web and is developing tools that can
verify that a given document is grammatically correct according to those standards.
The XML standard, already widely adopted commercially as a data interchange
format, forms the syntactic base for this layered framework. XML is semantically
neutral, so the resource description framework (RDF) adds a protocol for defining
semantic relationships between XML-encoded data components.
