Quiz: Which % of world governments have a Web site?
98%
A great first step …….
Objectives
• Improve impact of investments• Reach citizens more easily (G2C)• Reach businesses more easily(G2B)• Improve inter-agencies
communications (G2B)• Providing services to more people,
organizations (e-inclusion)• Involving more people, organizations
in government activities, capturing feedback, etc (e-participation)
e-Government
Using the Web and ICT to serve consistencies better
Governments move to digital age!

Summary
One-stop shop portals not entirely
successful
- People typically don’t use official websites- Not necessarily user-oriented,
interesting- Expensive
e-Government:Challenges
The simplistic assumption that e-governance is all about technology, and notreform, is one of the main reasons why many an e-government project fails. Onlycountries strong in governance and committed to reform can hope to succeed intheir e-government efforts. - K. Ashok Vardhan Shetty, 2003

Definition
WHAT IS OPEN GOVERNMENT DATA?
“Open”
material (data) is open if it can be freely used, reused and redistributed by anyone
“Government data”
data and information produced or commissioned by government or government controlled entities.

Government 2.0 is the DEMOCRATIZATION of government processes, services and data.
Open Government = Gov 2.0
• Gov 2.0 is an attempt to revolutionize government and the way that government does business
• Gov 2.0 allows for complete transparency, collaboration, participation, and innovation by incorporating emerging technologies.
• Gov 2.0 is a helpful and quick way to get in touch with the government and connect employees and programs
• Gov 2.0 gives users the choice to interact or collaborate in a social media dialogue as well as being in a virtual community
10
TRANSPARENCYbe able freely to access government data
and information and to share that information with other citizens.
RELEASING SOCIAL AND COMMERCIAL VALUE
the creation of innovative business and services that deliver social and commercial
value
PARTICIPATORY GOVERNANCEmaking a full “read/write” society, not just about knowing what is happening in the governance process but being able to
contribute to it.
WHY OPEN GOVERNMENT DATA?
11
“Information maintained by the
Federal Government is a national asset.”
President Obama January 21, 2009
Transparency and Open Government

Data.gov
• The first phase of Data.gov features downloadable federal data sets organized by category and federal organization.
• Data sets are available for download in XML, CSV, and shape file formats.
Launched on May 21, 2009, Data.gov allows citizens to participate by leveraging federal data sets to build applications, conduct analysis, and perform research.

Data.gov.uk
Establishment of the Public Sector Transparency Board chaired by Francis Maude, Minister for the Cabinet Office
The Board will be responsible for setting open data standards across the public sector, publishing further datasets on the basis of public demand
Prime Minister, David Cameron, writes to all government departments, 31 May 2010: instructing them to free up more datasets as part of Transparency Agenda

1. Complete: All public data is made available. Public data is data that is not subject to valid privacy, security or privilege limitations.
2. Primary: As collected at the source, with the highest possible level of granularity, not aggregate or modified, not via form-based queries.
3. Timely: Made available as quickly as possible and necessary.
4. Accessible: Available to widest range of users for widest range of purposes.
5. Non-discriminatory: Available to anyone, with no requirement of registration
6. Machine-processable: Structured to allow automated processing.
7. Non-proprietary: Available in an open, standard, format over which no entity has exclusive control.
8. License-free: Not subject to copyright, patent, trademark or trade secret regulation. Reasonable privacy, security and privilege restrictions are allowed.

Governmental Linked Data & The
Semantic Web
Summary
Semantic WebMachine-understandable Information: a web of data, in some ways like a global database.
“I have a dream for the Web [in which computers] become capable of analyzing all the data on the Web – the content, links, and transactions between people and computers. A ‘Semantic Web’, which should make this possible, has yet to emerge, but when it does, the day-to-day mechanisms of trade, bureaucracy and our daily lives will be handled by machines talking to machines. The ‘intelligent agents’ people have touted for ages will finally materialize.”– Tim Berners-Lee, 1999

• Use URIs as names for things• Use HTTP URIs so that people can look up those names• When someone looks up a URI, provide useful information, using the standards• Include links to other URIs so that they can discover more things

Step 1: Understand the principles
Five Steps to publish linked dataA quick overview
Step 2: Understand
your data
• What are the key things present in your data?(People, Places, Events, Books, Films, Photos, etc.)
• What vocabularies can be used to describe these?(FOAF, SIOC, Dublin Core, SKOS, etc)
29
Step 3: Choosing Cool URIs
• use HTTP URIs http://example.com/thing Thing http://example.com/thing.rdf RDF data http://example.com/thing.html HTML page
• dereferenceable URI (hash or slash)

Step 4: Setup infrastructure
Five Steps to publish linked dataA quick overview
31
a mechanism defined in the HTTP specification that makes it possible to serve different versions of a document (or more generally, a resource) at the same URI, so that user agents can specify which version fit their capabilities the best.
- Test your content negotiation (install the LiveHTTPHeaders and
Modify Headers extentions for Firefox)
Step 5: Link to other available data sets

Linking methods - Linking Algorithms, String Matching, Common Key Matching, Property-based Matching

Quiz: Why We should care about the Semantic Web?
Links at a semantic level
Integration
A second step …….
• As ‘raw’ as possible before analysis• XML, CSV/TXT, RSS, Keyhole Markup Language
(KML/KMZ), ESRI Shapefile• Avoid datasets in the following formats: PDF and HTML
(e.g., HTML tables containing data)
• Machine readable• Preference for structured datasets• Data that can be used for multiple purposes• Data that is largely free from interpretation and value
judgments (observational, unbiased data)• Datasets that can be mashed-up with others (brought
into context using lightweight web programming techniques and technologies)
Machine readable formats
However, the Semantic Web can add more valuesRaw Data is useful
40
Open Data starts with making available the data that you already have, in whatever format.
• Equal access for all• Licensing, legal issues• Transparency• Changing the way government works

Governmental Linked Data & The

Summary
Data.gov, along with a number of other data-related sites of the government such as USAspending.gov and Apps.gov, are slated to be shut down due to budget cuts. The current annual budget of $37 million will be reduced to $2 million. – (Guardian April 11)

The Web is not “Technology”. It is “humanity connected by technology”
Open Government Data is cost-effective tool for governments to improve service to citizens, civil society and business.
Linked Data and open data are often used interchangeably, but they are not the same thing.
Linked Data is data that is structured in such a way that data sets can be combined to create something greater than the sum of its parts.
Linked government data will interconnect different datasets across local governments, organizations, and nations.
