The document discusses the potential of decentralized open data for empowering world citizens, emphasizing the need for accessible and user-friendly interfaces such as voice technologies. It highlights the issues faced by data consumers and producers, particularly in resource-limited settings, and proposes solutions like micro-server infrastructure and citizen journalism. Ongoing projects like Radiomarché and Foroba Blon demonstrate successful implementations of these concepts to enhance data sharing and communication.

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 languages PMOD - June 2012 Open Data for World Citizens 7/19
- 8. A simple question... How can everyone benefit from Open Data ? Part of the solution: Voice interfaces DownScaled infrastructures PMOD - June 2012 Open Data for World Citizens 8/19
- 9. 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 languages PMOD - June 2012 Open Data for World Citizens 9/19
- 10. 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
