These expectations can be traced to three different perspectives
on the Semantic Web. The Semantic Web is portrayed as: (1) a universal library,
to be readily accessed and used by humans in a variety of information use contexts; (2) the
backdrop for the work of computational agents completing sophisticated activities on behalf
of their human counterparts; and (3) a method for federating particular knowledge bases
and databases to perform anticipated tasks for humans and their agents. McComb (2004)
defines the killer application in the Semantic Web as a radical improvement over search and
agent technology. An agent is a program to which an individual delegates some authority
to act on the individual??™s behalf and then releases to act autonomously. The Semantic Web

Semantic Web is the assumption that adding formal metadata that describes a Web resource??™s
content and the meaning of its links is going to substantially change the nature of the way
that computers and people find material and use it.
