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

What is Linked Open Gov Data?

Governement Data
Creating Knowledge

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
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.

Open data for smart cities

  • 1. Open Data Potential for Smart Cities Prof. Sören Auer
  • 2. Creating Knowledge out of Interlinked Data The Web evolves into a Web of Data Linked Open Data Facebook Open Graph
  • 3. 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?
  • 4. 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
  • 5. 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
  • 6. 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
  • 7. 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
  • 8. Creating Knowledge out of Interlinked Data What is Linked Open Gov Data? Linked Data Linked Open Governement Data
  • 9. 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
  • 10. 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...
  • 11. Creating Knowledge out of Interlinked Data • Transparency • Accountability • Efficiency • Public Service Delivery • Engagement • Data Improvement • Societal value • Economic value Open Data Benefits
  • 12. 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
  • 13. 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
  • 14. 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)
