linked data for development - victor de boer & christophe guéret
DESCRIPTION
Victor and Christophe introduce Linked Data for Development and highlight some examples. They explore possibilities to make linked data available in rural developing regions, through a voice/local radio interface and other low-infrastructure solutions.TRANSCRIPT

Need for data 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.

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

Infrastructure
• No internet,
• No bandwith,
• No computer,
• No electricity
• Cost – Total cost of ownership

Interface
• Low literacy
• Low education
• Small languages
• low capacity to interpret data, and illiteracy;

Relevancy
• No local content
• No local ownership
• Power balance, culture, apathy, lack of incentives, dis-empowerment

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

Low-powered hardware
• OLPC XO laptop
• Raspberry Pi
• Sheevaplug etc.

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!
