However, as mentioned in the
earlier section, there is a need to represent the multimedia data on the Semantic
Web in an efficient way. In the following section, we review some of the related
work done on the topic.

Ontology/Schema-Based.Approaches
Ontology-based approaches have been frequently used for multimedia annotation
and retrieval. Hyvonen, Styrman, and Saarela (2002) proposed ontology-based
image retrieval and annotation of graduation ceremony images by creating hierarchical
annotation. They used Prot?©g?© (n.d.) as the ontology editor for defining the
ontology and annotating images. Schreiber, Dubbeldam, Wielemaker, and Wielinga
(2001) also performed ontology-based annotation of ape photographs, in which they
use the same ontology defining and annotation tool and use Resource Definition
Framework (RDF) Schema as the output language. Nagao, Shirai, and Squire (2001)
have developed a method for associating external annotations to multimedia data
appearing over the Web.
