E
-
Government Conference, White House Conference
Center, September 8, 2003.


SICoP Was Chartered by the Knowledge Management
Working Group of the CIO Council’s Best Practices
Committee in March 2004.


SICoP was co

3. Workshops and Conferences


Sir Tim Berners
-
Lee at the SWANS
Conference, April 7, 2005, on the
Government Role:


Making public data available in standard
Semantic Web formats.


Requiring funded data to be available in
Semantic Web formats


Encouraging flagship applications.


Supporting Web Science research for
advanced tools.

3. Workshops and Conferences

Work locally

Work in wider group

Fast: Just do it

Slow: Committees!

Concepts match local needs

Have to adapt to other group's
concepts

Less usable later

Later, serendipitous reuse

Start locally

Later negotiate

Sir Tim Berners
-
Lee at the SWANS Conference, April 7, 2005, on
“the constant tension”

Keep a wise balance.

The semantic web allows a mixture of the two
approaches, and smooth transitions between them.

4. Pilots


SICoP is Conducting Pilot Projects at the Request of the
FEA PMO, AIC, and others:


4.1 Formal Taxonomies for the U.S. Government


4.2 Ontology for Indicators


4.3 Federal Enterprise Reference Model Ontology (FEA
-
RMO)


4.4 Building a National Health Information Network Ontology


4.5 Public Domain Databases for Semantic Searching and
Ontology Building


4.6 Ontology and Taxonomy Coordinating Work Group
(ONTACWG)


4.7 Composite Application Solution with Semantic Technologies


4.8 Semantic Technology Profiles for the FEA Data Reference
Model


4.9 FEA Data Reference Model Use Cases

SICoP has mapped its activities to the FEA PMO Action Plan FY 2005
-
2006
(see April 21st AIC Meeting).

5. The Semantic Web


Semantics


not new


Web


not new


Semantic Web


putting semantics on the Web is new:


Sir Tim Berners
-
Lee:


"The Semantic Web is an extension of the current web in which
information is given well
-
defined meaning, better enabling
computers and people to work in cooperation.”


“A new form of web content that is meaningful to computers [that]
will unleash a revolution of new possibilities.”


“OWL is an important step for making data on the Web more
machine processable and reusable across applications.”


Just as databases tables are connected through “joins”,
multiple distributed information representations can be
strung together through “semantic joins.”

Added from Discussion/Questions


Tim Berners
-
Lee (June 2005 Interview by Andrew Updegrove at
http://www.consortiuminfo.org/bulletins/pdf/jun05/feature.pdf):


One of the criticisms I hear most often is, “The Semantic Web doesn’t do
anything for me I can’t do with XML”. This is a typical response of someone who
is very used to programming things in XML, and never has tried to integrate
things across large expanses of an organization, at short notice, with no further
programming. One IT professional who made that comment around four years
ago, said a year ago words to the effect, “After spending three years organizing
my XML until I had a heap of home
-
made programs to keep track of the
relationships between different schemas, I suddenly realized why RDF had been
designed. Now I use RDF and its all so simple


but if I hadn’t have had three
years of XML hell, I wouldn’t ever have understood.”


Many of the criticisms of the Semantic Web seems (to me at least) the result of
not having understood the philosophy of how it works. A critical part, perhaps not
obvious from the specs, is the way different communities of practice develop
independently, bottom up, and then can connect link by link, like patches sewn
together at the edges. So some criticize the Semantic Web for being an (clearly
impossible) attempt to make a complete top down ontology of everything.



Doug Whall, CIA:


Question: How do you get started with all of this


build on previous work or jump
right in with ontologies? Answer: Usually “build on previous work”
