Open data for smart cities Open data for smart cities Presentation Transcript

  • Open Data Potential for Smart Cities Prof. Sören Auer
  • Creating Knowledge out of Interlinked Data The Web evolves into a Web of Data Linked Open Data Facebook Open Graph
  • Creating Knowledge out of Interlinked Data Trans- port/ Mobility Energy Edu- cation Commu nication Cuture Econo- my Gover- nance Aspects of Smart Cities What connects all these Smart City aspects?
  • Creating Knowledge out of Interlinked Data • Open Data Strategy (Ref: IP/11/1524) expected to deliver €40 billion boost to the EU's economy each year • Data becomes a tradable commodity, “the value of data increases the more you share it” Potential of Open Data ©Nigel Holmes 2012 / from The Human Face of Big Data
  • Creating Knowledge out of Interlinked Data Extreme variety of • Data sources • Data structures/data models (XML,CSV,RDB,…) • Stakeholders: Data owners/publishers & consumers (authorities, administrations, citizens, companies, …) • Licenses (proprietary, CC, Open Data, …) Not only Big Data, also large amounts of „Small Data“ What are the challenges
  • Creating Knowledge out of Interlinked Data 1. Uses RDF Data Model Addressing the challenges with Linked Data SRII-Asia2013 Bangkok 17.9.2013 SRII_Thailand organizes starts takesPlaceIn 2. Is serialised in triples: SRII_Thailand organizes SRII-Asia2013 SRII-Asia2013 starts “20130917”^^xsd:date SRII-Asia2013 takesPlaceAt Bangkok 3. Uses Content-negotiation
  • Creating Knowledge out of Interlinked Data • Uses established Web Technologies (HTTP, URI etc.) • No centralized authority required • RDF is a lingua franca for integrating data on the Web • Entities, attributes and properties can be uniquely identified • Provenance built-in • Easy to migrate from shallow semantic representations (thesauri, vocabularies) to complex ones (ontologies) • Mature stack of standards and technologies available Advantages of Linked Data
  • Creating Knowledge out of Interlinked Data What is Linked Open Gov Data? Linked Data Linked Open Governement Data
  • Creating Knowledge out of Interlinked Data Open Government Data Ecosystem for Smart Cities Politics • On different levels: (supra-) national, regional, municipal Civil society • Grass-roots initiatives • NGOs • Pluralism Business • Startups • SMEs • Large companies Research • Science • Collaborative projects
  • Creating Knowledge out of Interlinked Data Open Data for Smart Cities: Who is it for?  Data literate citizenry  Data journalists  Policy experts  Decision makers  Mobile and web developers  Academics / researchers  Public bodies  Companies  Civic society / NGOs  And so on...
  • Creating Knowledge out of Interlinked Data • Transparency • Accountability • Efficiency • Public Service Delivery • Engagement • Data Improvement • Societal value • Economic value Open Data Benefits
  • Creating Knowledge out of Interlinked Data • Let citizens experiment with apps visualizing governmental spending – leverage the creative potential • Reach better societal agreement • Identify overspending, potential for savings, misuse Open Budget Data
  • Creating Knowledge out of Interlinked Data • It is hard for public transportation agencies to develop the best user interfaces • Why not letting citizens and companies solve this? Open Transportation Data – Increase Efficiency of Public Transport
  • Creating Knowledge out of Interlinked Data • Publish Open Data in RDF reusing vocabularies which can be understood and combined by apps in unforeseen ways What has to be done? Where we are now Where we should be make your stuff available on the Web (whatever format) under an open license link your data use URIs to denote things use non-proprietary formats (e.g., CSV instead of Excel) make it available as structured data (e.g., Excel instead of image scan of a table)
  • Creating Knowledge out of Interlinked Data
  • http://lod2.eu Creating Knowledge out of Interlinked Data By opening data companies, organizations and interested citizens are able to build applications and mashups on to of the data. Open Data …applications follow
  • http://lod2.eu Creating Knowledge out of Interlinked Data Service-orientation to increase “customer” satisfaction (businesses, citizens) • Linked Data and apps, visualizations, mashups build on top help businesses and citizens to build value-added services Intra-government collaboration for efficient/effective government • Linked Data helps establishing a pay-as-you-go data integration ecosystem Increased transparency • Standardized vocabularies allow to quickly compare data from different sources and do fact checking Not using the chances arising from the interlinking of government data puts the development of our data economy and the realization of associated positive societal and economical effects at risk. Summary: Benefits of Linked Data
