Micro-bloggingSending 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

Linked DataAccording 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 dataThe 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.caBased 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-bloggingWe 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
