  • CAUTION! DIGITAL DIVIDE AHEAD
  • Web Alliance for Regreening in Africa Washington, 13-15 May 2013 4 W4RA : Information exchange and knowledge sharing in rural Africa
  • World Wide Web as Instrument of Empowerment “Our success will be measured by how well we foster the creativity of our children. Whether future scientists have the tools to cure diseases. Whether people, in developed and developing economies alike, can distinguish reliable information from propaganda or commercial chaff. Whether the next generation will build systems that support democracy and accountable debate. I hope that you will join this global effort to advance the Web to empower people.” Sir Tim Berners-Lee, inventor of the Web:
  • Can the Web (be made to) mean something for knowledge sharing even under very constraining conditions? No internet, no computer, no electricity Multitude of languages, levels of literacy
  • A window of opportunity…
  • •No. 1 source of information •Interactive radio programs •Huge listening base Another window: rural community radios
  • • Integrate local community radios and mobile ICT for knowledge sharing • Better support and integrate local languages in voice-based services – Development of appropriate speech elements (text-to-speech and Speech recognition) • Develop a free and open source toolbox for local developers. • Investigate self-sustainability – Develop appropriate business models – In collaboration with local communities.
  • (adapted) Living Labs • Involvement of local communities – Trust and ownership – Co-creation • Bottom-up: field visits, workshops, demos, roa dshows, etc • Local communities: innovation co- creation, “Living Labs” socio-technical approach – Use case gathering – Observation and prototyping – Test, adapt
  • June 2013Jan 2010 First cycle: Knowledge sharing for regreening Second cycle: Use Case elicitation and selection RadioMarché: Pilot System development (Malian French) RM: 3rd version (Bambara,Bo mu) Jan 2011 Jan 2012 Jan 2013 First field trip: Burkina Faso Second field trip Mali, Burkina Faso, Ghana RM: 4th version Third field trip Mali Fourth field trip Mali Fifth field trip Mali Foroba Blon: pilot version FB: 2nd version (Bambara,Bo mu) Third cycle: Requirements elicitation and validation Business Model integration Sixth planned field trip Mali Fourth cycle Use case and Requiremen ts validation Fifth cycle: Use case and Requirements validation Sept 2009 Cycle 0 Preliminary visit BF sept 2009 RM: 2nd version (productio n version) FB: 3rd version (Bambara,Bo mu)

  • Deployment
  • Evaluation • Limited usage due to: – Political situation – Ecological situation – Social barriers – Technical issues • Feedback informs next phase – More languages (Bambara, Bomu) – More radio stations – End user
  • Subsequent phases • More languages: Bambara and Bomu • More usage • In a way, we are “too succesful”: Too much demand – not serving the value chain – Should we include this in the application? – Cf. Marktplaats?
  • Business model integration Onno Wassenaar

  • Research questions • Q1 [immediate]: Can the Web (be made to) mean something for knowledge sharing even under very constraining conditions? – No internet, no computer, no electricity – Multitude of languages, levels of literacy • Q2 [Web future]: Can we have a Web of Speech? – After all, human communication: talking >> writing
  • More research questions • Data management via voice – Data presentation/UI – Voice-based browsing • Linked data / microservers – Downscale2012 @ ESWC – Downscale2013 @ OKCon • Integration with (development) economy • ICT development in rural areas – Living Labs, Sustainability
  • Out of Africa: Lessons for ICT projects • Problem- rather than solution-driven • Many cycles • Open mind – (low tech may be the best solution) • Integrated approach – Context, business model • Be inclusive rather than exclusive
