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

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
