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
