DOWNSCALE: Linked Data for Development
Victor de Boer - Anna Bon - Christophe Guéret Open Development Camp 2014
www.worldwidesemanticweb.org
Need for information sharing in rural
developing areas
• Agriculture – Market Prices – Business opportunities – Support – Sharing indigenous
knowledge – Etc.
• Health – Prevention – Access to healthcare – Detection of disease
outbreak – etc.
• Education • Etc.
Based on Sbc4d.com
Barriers to the Internet
1. Technology: The lack of connectivity and electricity, cost of devices and cost of connection are limiting the adoption and usage of new technologies;
2. Capacity: Lack of time and resources limits the participation in data sharing processes. There are also issues related to low education levels, low capacity to interpret data, and illiteracy;
3. Relevance: Power balance, culture, apathy, lack of incentives, lack of interest and dis-empowerment are also all threats to having citizens engage in data sharing.
Information sharing should be made
1. usable on small, affordable, hardware deployed in various connectivity contexts;
2. accessible to individuals with varied cultural backgrounds / literacy levels;
3. relevant and directly useful to the target public they aim to empower.
Infrastructure
Interface
Relevancy
Why the Semantic Web?
• Information (from NGOs) in silos – Specific products – Specific communities
• Lot of knowledge is lost due to lack of publication
Sharing (heterogeneous) knowledge is essential
• LD is well-suited because of: – Language-agnostic – Interface-agnostic – De-centralised authoring
• Slicing
– Re-usability • Local • Global

Web of Documents (WWW) Linked Documents
Web of Data Linked Data Semantic Web
With the mainstream
• Dev. countries can leapfrog directly into the information age, – jumping many phases of
immature technologies
• Linked Data is mainstream
computer science research. – Let’s worry about the 4.5 B
unconnected prosumers now!

Interface: Mobile phones and Community radios

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
Market Information
Citizen Journalism
Event Organiser
Bottom-up
•Involvement of local communities –Trust and ownership
–Co-creation
•Bottom-up: field visits, workshops, demos, roadshows, etc
•Local communities: innovation co-creation, “Living Labs” socio-technical approach
–Use case gathering
–Observation and prototyping
–Test, adapt

Low-powered hardware
• OLPC XO laptop
• Raspberry Pi
• Sheevaplug etc.
ERS: Distributed Networks Mesh VS Infrastructure network

STUDENT PROJECTS at VU AMSTERDAM
ICT4D Course
•MSc Computer Science course –this year 3rd time
–Core Computer Science: CS4D
•Make students aware of importance of context •Hands-on experience
•Train CS researchers in ICT4D
Nichesourcing for pluvial data digitization for the Sahel
[M.Sc. thesis by Binyam Tesfa]
1.How does violent conflict in recipient countries affect aid activities?
2.How does aid spending as registered in the IATI standard compare to World Bank indicators?

IATI2LOD (Kasper Brandt)
Voice Interface design for low-literate users
•Design guidelines (Deepak Chhettri) •Evaluation experiment (Onur Akgun and Serdar Parlak) •Access to DBpedia / Wikipedia (Rianne Nieland)
Icon-based interaction
(Project Julia Salomons)
Knowledge sharing platform (aka “The Box”)
•Brings together many strands •Rapid prototyping platform
–Flexible use cases •Rainfall, land rights, market places, seed exchange, messaging platfomr
–Knowledge sharing on multiple levels –Small, low-power, low-cost hardware
–Multi-model interface
–Privacy and data sharing
