Appropriate annotation of documents is a central aspect of
efficient media management and retrieval. As ontology-based descrip-
tion of documents and facts enables exchange and reuse of metadata
among communities and across applications, the annotation of personal
media collections using Semantic Web technologies benefits from existing
(and evolving) information sources on the Internet. This paper addresses
conceptual and technical issues of Web search within community-built
Semantic Web content to retrieve useful information for personal media
annotation. After analyzing application scenarios, we introduce a generic
and extensible Semantic Web Search Component, which facilitates spe-
cific search configurations. As a sample application, we deployed the
component within our ontology-based media management system, in-
cluding evaluation and remarks on quantity and quality of search results
with regard to community-built Semantic Web content.
