Micro-blogging Sending and publishing brief text media or micromedia Content ranges from News, and self-promotion, conversations, pass-along values to babbles and spam Today we call blogging under 140 characters, micro-blogging
Micro-blogging services
Linked Data According to Sir Tim Berners-Lee, To have our data linked properly, we have to Use URIs as names for things Use HTTP URIs so that people can look up those names When someone looks up a URI, provide useful information, using the standards (RDF, SPARQL) Include links to other URIs. so that they can discover more things
More Linked data The WWW with Linked data Seems like a Giant Global Graph Which is content + pointers + relationships + descriptions
Tweet…Tweet… Answer just a single question: “what are you doing?” in just 140 characters 50 million live accounts Using proprietary software Tagging mechanism (#hashtags) Centralized service Twitter blocks visualizes your network
Identi.ca Based on StatusNet (previously called laconi.ca) Free software (you may read it open source) Licensed under Aferro GPL version 3+ RDF friendly Exports user’s social network in foaf format Twitter-compatible API Cross-posting to Twitter Facebook Integration Automatic URL-shortening And Group mechanism
Semantic Micro-blogging We want data to be linked In other words We wanted them to be semantic-web-friendly In this case we need our updates to be accessible Machine-understandable Machine-reasonable And contain Reusable data
Where are we? Some research and modeling has been made by John Breslin and colleagues (http://smob.sioc-project.org) FOAF and SIOC Ontologies Automatic/manual annotation in micro-blog posts Linking existing URIs of the related concepts Distributed architecture
Ideas (not new, not done yet) Extensive use of URIs for users, topics, places…everything Commitment of social network services to open standards (FOAF, SBIC, DOAP, etc.) Semantics-oriented aggregators and clients
