SemanticXO connecting the XO with the World’s largest information network Christophe Guéret, Stefan Schlobach c.d.m.gueret@vu.nl, s.schlobach@vu.nl Vrije Universiteit Amsterdam (Nederlands) http://www.slideshare.net/cgueret/ International Conference on e-Technologies and Networks for Development (ICeND2011)Christophe Guéret - @cgueret (VUA) SemanticXO ICeND2011 - August 4, 2011 1/25

The next 20 minutes Semantic Web + XO = SemanticXO One Laptop Per Child and the XO Linked Data / the Semantic Web Goals of the project SemanticXO Publish and Consume Linked Data with the XO Your questions, remarks, suggestions ! Work in progressChristophe Guéret - @cgueret (VUA) SemanticXO ICeND2011 - August 4, 2011 2/25

One Laptop Per ChildChristophe Guéret - @cgueret (VUA) http://www.flickr.com/photos/erikcharlton/3336627233 SemanticXO ICeND2011 - August 4, 2011 3/25

One Laptop Per Child (OLPC) “Empower the world’s poorest children through education [by providing them] with a rugged, low- cost, low-power and connected laptop” – laptop.org Mission principles 1.Every child owns his laptop 2.Action focused on early education (6-12) 3.No one gets left out 4.Connected device 5.Open source software free to grow and adaptChristophe Guéret - @cgueret (VUA) SemanticXO ICeND2011 - August 4, 2011 4/25

The XO laptop and Sugar Collaborative learning Activities instead of applications Journal of usage (critical thinking) http://www.flickr.com/photos/curiouslee/3985626381/Christophe Guéret - @cgueret (VUA) SemanticXO ICeND2011 - August 4, 2011 5/25

Example of current capabilities Fully featured web browser Snapshot of Wikipedia Activities running simultaneously can share data Bulk export of journal entries (for backup) The XO is Web 2.0 ready : create and share data in data silosChristophe Guéret - @cgueret (VUA) SemanticXO ICeND2011 - August 4, 2011 6/25

Linked Data (aka Semantic Web)Christophe Guéret - @cgueret (VUA) http://www.flickr.com/photos/erikcharlton/3337465138 SemanticXO ICeND2011 - August 4, 2011 7/25

Linked Data “Using the Web to connect related data that wasnt previously linked, or (...) lower the barriers to linking data currently linked using other methods” – linkeddata.org Publish data on Internet as already done for documents Design principles 1. Use URIs as names for things 2. Use HTTP URIs so that people can look up those names 3. Bind useful information to the URI, using the standards 4. Include links to other URIsChristophe Guéret - @cgueret (VUA) SemanticXO ICeND2011 - August 4, 2011 8/25

SemanticXO Goal: make the XO ready for the Web 3.0 by extending its software stack OLPC contributor project started in October 2011 for 12 months http://semweb4u.wordpress.comChristophe Guéret - @cgueret (VUA) SemanticXO ICeND2011 - August 4, 2011 16/25

What is there to expect ? Benefits for the operating system Flexible and dedicated data storage solution Benefits for activities developers Easier data access and integration Access to the content of the LOD Cloud Benefits for end users Increased sharing opportunitiesChristophe Guéret - @cgueret (VUA) SemanticXO ICeND2011 - August 4, 2011 17/25

How to do it ? Implement a software stack “Triple store” to store the data Interface to publish/consume data HTTP server Programming Interface (API) Triple store and filesChristophe Guéret - @cgueret (VUA) SemanticXO ICeND2011 - August 4, 2011 18/25

Example of application Knowledge Acquisition of traditional Amerindian World views using Serious GamesChristophe Guéret - @cgueret (VUA) SemanticXO ICeND2011 - August 4, 2011 19/25

Under the hood : data model Resources and relationsChristophe Guéret - @cgueret (VUA) SemanticXO ICeND2011 - August 4, 2011 20/25

Under the hood : data stored Set of triples (SPO) Same structure everywhere in the Cloud e.g. Can be linked to cities for provenance Subject Predicate Object olpc:resource/a05864b4 rdf:type olpc:Item An olpc:resource/a05864b4 olpc:name "image114" item olpc:resource/a05864b4 olpc:hasDepiction "image114.jpg" olpc:resource/a82045c2 rdf:type olpc:Box A box olpc:resource/a82045c2 olpc:hasItem olpc:resource/a05864b4 olpc:resource/78cbb1f0 rdf:type olpc:Box ... ... ...Christophe Guéret - @cgueret (VUA) SemanticXO ICeND2011 - August 4, 2011 21/25

New data flows Data distribution Easy accessChristophe Guéret - @cgueret (VUA) SemanticXO ICeND2011 - August 4, 2011 22/25

Partnership with W4RA-VOICES Web alliance for Regreening in Africa (W4RA) “initiative to help extend the Web benefits of the knowledge society and economy to people in rural communities in Africa” http://www.w4ra.org/ http://vimeo.com/26520353 Project VOICES funded by European UnionChristophe Guéret - @cgueret (VUA) SemanticXO ICeND2011 - August 4, 2011 23/25

More about W4RA-VOICES Aimed at expanding knowledge creation and sharing, especially in poor communities in Africa, with have limited access to the Web. Use voice technologies, mobile phone and community radio for communication and access to information Working to create access to the Linked Open Data and to create an Open Web of Speech Use triple stores and RDF for spoken dataChristophe Guéret - @cgueret (VUA) SemanticXO ICeND2011 - August 4, 2011 24/25

Take home message Linked Data = best practices for publishing and interlinking structured data on the Web Web scale data sharing Lots of data published as Linked Data Worlds largest information network Linked Open Data can contribute to development with more, easier, data sharingChristophe Guéret - @cgueret (VUA) SemanticXO ICeND2011 - August 4, 2011 25/25
