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

User Benefits
• Additional metadata• Contextual search
(e.g. people and places)
• Multilingual retrieval• DBpedia provides resource
descriptions in 90+ languages• Named entity label translation
in search & retrieval
• Geographical retrieval• Map-based search interface• ‘Regions of relevance’ for keyword searches – disambiguation!

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
