The document discusses key issues around applying semantic web technologies to multimedia data including metadata, annotation, integration and inference. It raises questions around what standards are needed to address these areas and how existing infrastructures could be used or extended to support tasks like feature extraction, tagging, reconciling tags and ensuring consistency at scale. Bridging semantic web approaches and multimedia will depend on the specific tasks and use cases.

2. I Want Multimedia Metadata Too!

3. The Answers Probably Probably not Depends Might scale, but what are you going to do with it? http://www.flickr.com/photos/-bast-/349497988/

4. Semantic Web Annotation Associating metadata with resources Integration Integrating information from various sources Inference Reasoning over the information we have. Could be light-weight (taxonomy) Could be heavy-weight (logic-style) OWL Integration RDF(S) RDF XML/URIs Annotation Integration Inference

5. Answers Do we need specific standards? What are the standards to address? Lots of effort on subsymbolic and symbolic data Use existing infrastructures Migration paths MPEG-7 or tagging? Fits with annotation Kind of fits with integration What about inference ?

6. Answers Feature Extraction? What are you going to do with the results? Scalable tagging? How do I reconcile tags? How do I ensure some consistency? Bridging the Gap Depends on what you’re doing
