Who are we talking about exactly? Data consumers that: (Computer) literate Early adopters of new technologies Data producers that: Have access to publication platforms Have a significant amount of data to publish Are trusted as data providers A tiny fraction of the 7 billion World CitizenPMOD - June 2012 Open Data for World Citizens 6/19

Data sharing need and issues Example needs Market prices Innovative agricultural techniques Information about stock of crops Issues Distances between rural communities in Sahel Limited infrastructure: no electricity, no computer, no Internet (but radio and mobile phones) Lack of relevant content, literacy and education, different languagesPMOD - June 2012 Open Data for World Citizens 7/19

A simple question... How can everyone benefit from Open Data ? Part of the solution: Voice interfaces DownScaled infrastructuresPMOD - June 2012 Open Data for World Citizens 8/19

Voice interfaces What ? Replace textual interfaces by speech Why ? Everyone can speak and listen Good mobile penetration in sub-Saharan Africa How ? Use and develop TTS and ASR technologies Deal with several local languagesPMOD - June 2012 Open Data for World Citizens 9/19

DownScaling infrastructures What ? Use a swarm of micro-servers instead of a central one Why ? Micro-servers are less costly Redundancy in the swarm improves robustness Decentralise => get closer to data consumers/producers How ? Use low-end hardware Adapt data technologies (in particular, Linked Data)PMOD - June 2012 Open Data for World Citizens 10/19

SemanticXO: data sharing stack for the XO Every XO is a data External Sugar applications activities publisher and consumer Structured HTTP Server data store API Does not rely on any central host Triple Web of Data store + Uses lightweight data files relays when neededPMOD - June 2012 Open Data for World Citizens 18/19

Take home message Widening the access to Open Data implies Developing voice-based interfaces DownScaling infrastructures For more information: http://worldwidesemanticweb.wordpress.com/ http://semweb4u.wordpress.com/ http://w4ra.few.vu.nl/ http://mvoices.eu/PMOD - June 2012 Open Data for World Citizens 19/19
