With our work, we want to….

• show how to make use of Linked Data by integrating the user annotation process with resource linkage

• demonstrate linkage in annotation clients• Video Annotation• Map Annotation

• focus on user-benefits

Annotations as Linked Data

• All annotations are exposed as Linked Data on the Web…• each annotation has a dereferencable URI• each annotation can be retrieved in RDF or HTML• annotations are linked to other resources (DBpedia, Geonames)

• Annotation data is expressed using the LEMO vocabulary• refines (reuses) terms of the Annotea vocabulary• extensible vocabulary architecture

Next Steps & Further Info

• Improve integration of linked data resources with retrieval infrastructure

• https://code.google.com/p/lucene-skos/

• Integrate with Open Annotation Collaboration efforts• http://www.openannotation.org/

• Deeper investigation of the map annotation use case• Benefit of annotations and tags for map geo-referencing• Spatial search & retrieval UIs
