2. New paradigms for microblogging
Digital Enterprise Research Institute www.deri.ie
 SMOB – Semantic MicrOBlogging
 http://smob.me - GNU/GPL
 Microblogging systems as walled gardens
 A distributed architecture for microblogging
 Lack of common representation formats
 An ontology stack for semantic microblogging
 No meaningful #tags
 Integration with the Linking Open Data (LOD) cloud
 Information overload
 Sharing spaces to enhance information delivery

3. Distributed architecture
Digital Enterprise Research Institute www.deri.ie
 Personal SMOB hubs spread all over the Web
 Ensure data privacy and ownership
 Synchronise together using SPARQL/Update + HTTP
 Can be used as read-write Twitter clients

4. Ontology stack
Digital Enterprise Research Institute www.deri.ie
 Reusing and combining popular models
 FOAF, SIOC, OPO, MOAT / CommonTag
 Can be reused in any Social Semantic Web context
 Microblog posts modelled in RDFa using this stack

5. Integration with the LOD cloud
Digital Enterprise Research Institute www.deri.ie
 Semantic tagging
 URIs being suggested when typing #tags
 Integration of microblogging within the LOD cloud
 Ability to add new services (e.g. enterprise microblogging)

7. Sharing spaces
Digital Enterprise Research Institute www.deri.ie
 Enhance delivery of microblog posts
 Defined using SPARQL CONSTRUCT rules
 Updated dynamically
 Ability to address which group(s) should get a message

8. Ongoing Work
Digital Enterprise Research Institute www.deri.ie
 sparqlPuSH
 Integrating SPARQL/Update and PubSubHubbub
 Scalability and real-time sync. between interested parties
 http://code.google.com/p/sparqlpush
 Twarql
 LOD-interlinking from streamed Twitter data
 Reusing the aforementioned ontology stack
 http://wiki.knoesis.org/index.php/Twarql
