  • Publishing Linked Data from Brazilian Politicians on the Web Lucas de Ramos Araújo Pablo N. Mendes Jairo Francisco de SouzaAt the Workshop on Semantics in Governance and Policy Modelling, Extended Semantic Web Conference 2011 ESWC2010. May 30, 2011 - Crete, Greece
  • Outline● Introduction● Background● Project Landscape● Linking Citizens and Politicians● Conclusion
  • Introduction: Motivation ● Why? ● Brazil has a substantial amount of government data available on the Web, but usually not structured ● Brazil ranks 61st in the United Nations E-Government Survey 2010 losing 16 positions since 2008 [1]. ● Brazilian citizens: over 90% of the interviewed have average, little or no interest in politics [2]. ● Mix information from different sources enable new services and offer new insights about the people and the government.[1] United Nations e-Government Survey 2010 (http://unpan1.un.org/intradoc/groups/public/documents/un /unpan038851.pdf )[2] Latin American Public Opinion (http://www.scielo.br/pdf/op/v15n2/09.pdf)
  • Introduction: Goal● Our goal? ● Collect data from Brazilian politicians from different sources and publish them as Linked Open Data. ● Enable reuse and interconnection between information from different sources, thus generating new knowledge. ● Engage citizens in actively participating in the decisions being taken by their elected government. ● Bridging a gap between the government and public opinion.
  • Background ● Linked Open Data, incrementally:★ make your stuff available on the Web under an open license★★ make it available as structured data★★★ use non-proprietary formats★★★★ use URIs to identify things, so that people can point at your stuff★★★★★ link your data to other data to provide contextTim Berners-Lees 5 star scheme. http://www.w3.org/DesignIssues/LinkedData.html
  • Data on the Web (1990s)< Approach: Integrate in-house, expose result of integrationBD Integrated Portal Consumer BD Data WEB BD Another Consumer ● One cannot anticipate all uses of his/her data – For some, a portal is a nice way to access data – For others, it is an obstacle on their way to create interesting applications
  • Data on the Web (linked!)< Linked Data Approach: expose individual data, expose linkage Portal BD Consumer LINKED DATA WEB BD BD Another MashupIntegrated Another Consumer Data ● A portal is just one option to look at the data. – Third parties have the freedom to re-purpose the data – Third-party perspectives may be useful for other people – May be useful even for the publishers portal!

  • Linking Citizens and Politicians● My city page: ● Emphasizing the interpretation that politicians represent a certain group of citizens
  • Visualization Perspectives● What is my elected representative working on? ● Start from keywords, dig into the text
  • Visualization Perspectives● Offering interfaces for different visualizations.
  • Flexibility in Exploration● Arbitrary queries on the data ● Representatives of states with high illiteracy that vote on propositions related to education SELECT DISTINCT ?politico ?estado ?analfabetismo WHERE { ?politico a dbpedia-owl:Politician . ?politico dbpedia-owl:birthPlace ?estado . ?estado dbpprop:analfabetismo ?analfabetismo . ?estado dbpprop:nome ?nome . ?voto <http://ligadonospoliticos.com.br/politicobr/politician> ?politician . ?voto <http://ligadonospoliticos.com.br/politicobr/voting> ?votacao . ?votacao <http://ligadonospoliticos.com.br/politicobr/proposition> ?proposicao . ?proposicao rdf:type polbr:proposicao. ?proposicao dcterms:description ?ementa FILTER (?analfabetismo > 20) FILTER regex(?ementa, "educação","i") } http://pt.dbpedia.org/?q=exemplos
  • Linking Citizens and Politicians● Connecting politicians to public opinion through social media.
  • Conclusion● Following best practices (such as LOD) to open data allows citizen developers to create interesting apps● We hope that more data and more applications will engage citizens in an active dialog with the government● As future work, we intend to: ● Update and link more data. ● Provide a friendly interface for query formulation ● Link propositions to LOD via entity extraction ● Engage more developers
