  • Linked Data for Kasper Brandt Victor de Boer KnowEscape workshop 19-9-2013
  • Introduction - IATI “IATI is a voluntary, multi-stakeholder initiative that seeks to improve the transparency of aid in order to increase its effectiveness in tackling poverty.”
  • Introduction - IATI users • Funders o Where is the money of my organisation spent? o Where do other organisations spend their money? • Governments o How much money is spent in my country? o What are the budgets or planned disbursements for my country? • Locals o What organisations are working in my area? o What projects are currently going on in my area? • Public o Where is my tax money going? o What are the organisations doing with my donations?
  • Introduction - IATI model Activities Organisations
  • Introduction - IATI model Codelists • Aid Type • Country • Currency • Geographical precision • Language • Location type • Organisation role • Policy marker • Region • Sector • Transaction type • Vocabulary
  • Introduction - Linked Data 1. HTTP URIs to name things 2. Create meaningful links to other datasets 3. No more data silos 4. Standardized vocabularies and ontologies 5. Query datasets through SPARQL
  • Introduction - Why IATI Linked Data? 1. Reusable vocabularies o Extract information automatically from the IATI data by making use of applications which are able to interpret standard vocabularies 2. Enrich IATI data o Link IATI data to external datasets in order to enrich the IATI data with additional information or metadata. 3. Donors can use their own Linked Data specification. o @Linked-data-uri attribute already exists in the IATI model.
  • Linked Data model 1. How can the IATI model best be converted to a Linked Data model? a. How can we create the Linked Data model in a structured manner? b. How can we keep track of provenance on the IATI data? c. What standard vocabularies can be reused for enriching the Linked Data model?
  • Model and links based on requirements elicitated from experts Iterative Requirements Engineering Process Model by Loucopoulos and Karakostas
  • Linked Data model - Example iati:activity/GB-CHC-285776-CHA024 iati:activity-transaction iati:activity/GB-CHC-285776-CHA024/transaction/42737 . iati:activity/GB-CHC-285776-CHA024/transaction/42737 iati:transaction-tied-status iati:codelist/TiedStatus/5 .
  • Linked Data model - Provenance • On file level o Not on activity level • A named graph per file, e.g.:iati:graph/dataset/World bank
  • Linked Data model - Vocabularies
  • Linked Data model - Triple store • Triples loaded into a ClioPatria triple store: o http://eculture.cs.vu.nl:1987/iati/home o Sparql endpoint o Dereferenceable URIs (http://purl.org/collections/iati/codelist/Sector/11 420) • Total number of triples: 36,629,017 • Total number of named graphs: 4,790 o Largest activities graph is UNOPS containing 1,231,896 triples • Takes approximately 30 minutes to load all data into the triple store. RDFLibPython RDF/Turtle
  • Linking datasets - Approach 1. In total, how much does a given country receive in aid? 2. A comparative index of aid versus the Human Development Index. 3. What is the geographic location of a project? How much aid went to a given province, constituency or village? o Is the aid spent in places where the need is highest? Is it well distributed across the country? o Can we attribute sub-national breakdowns for aid so we can see how much goes to different parts of recipient countries? 4. How does violent conflict in recipient countries affect aid activities? 5. How does aid spending as registered in the IATI standard compare to World Bank indicators?
