To a computer, the Web is a flat, boring world, devoid of meaning.
This is a pity, as in fact documents on the Web describe real objects and
imaginary concepts, and give particular relationships between them.
example, a document might describe a person.
title document to a house describes a house and also the ownership relation
with a person.
semantics to the Web involves two things: allowing documents which have information
in machine-readable forms, and allowing links to be created with relationship
when we have this extra level of semantics will we be able to use computer power
to help us exploit the information to a greater extent than our own reading.
