However, software agents cannot understand the meanings
of the terms differently represented in different systems and also process them
without human intervention.
In the integration approach based on the Semantic Web, the software agents understand
the meanings of the terms and automatically process them by exploiting the
RDF and ontologies as illustrated in the upper and right part of Figure 11. Assume
that two different systems have same term, Lincoln that actually means different
things while the two systems have different terms, stayed and lodged that mean the

same thing. For example, consider the sentence, ???President Lincoln visited Lincoln
and stayed (or lodged) at Husker.??? The sentence is written in the RDF in the manner
as shown in Figure 11. The software agents capture the instance of the RDF and
understand the meanings of the terms by referring to ontologies.
