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
