Compared
with keyword-based approaches, the XML paths from the root node to the keywords
are able to fully express the semantic meaning of the multimedia data. In the case of
the New York image, semantically meaningful XML annotations would be ???image/
semantic/foreground/object=Statue of Liberty, image/semantic/foreground/ object
= Sea, image/semantic/ background/ object = Sky, image/semantic/background
/object =Clouds???. The semantics in XML paths provides us with an added advantage
by differentiating the objects in the foreground and background and giving more
meaningful annotation.
We emphasize that the annotation performed using our approach is domain-specific
knowledge. The same image can have different annotation under a different XML
schema that highlights certain semantic characteristics of importance pertaining to
that domain knowledge. We simply use the schema of Figure 3 that presents image
foreground and background object information as a running example.

The goal of the proposed system is to represent multimedia data obtained from the
Web in a meaningful XML format.
