Growing ocean of data

Hard drive data storage technology grewfrom 10 megabytes for $300 in 1980 to500 gigabytes for $100 in 2007)

Computing power doubling every 24

months

Digital database doubling every 18months

The Internet has revolutionized thesharing of information

Trends in corporate IT

IT function is becoming less separated fromthe rest of the company

Line managers and staff are changing frombeing IT's customers to becoming its co-

creators

Semantic Web approach and initiatives

The World Wide Web Consortium (W3C) isan international non-profit partnership

W3C Mission: To lead the World WideWeb to its full potential by developing

protocols and guidelines that ensures long-term growth for the Web.

How?Through the creation of Web

standards and guidelines. Since 1994,W3C has published more than ninety suchstandards, called W3C Recommendations

Technologies and standards

XML provides syntax; allows users to addarbitrary structure to their documents

Resource Description Framework (RDF)Meaning expressed in sets of triples, like the

subject, verb and object of a sentence. Semantic web ontology (OWL) used to

develop domain-specific vocabularies

Simple Knowledge Organization Systems(SKOS) - Supports the use of knowledgeorganization systems (thesauri,classification schemes, and taxonomies

Markets

ICT - $3.5 Trillion globally Consumer internet

Acct for 25% of ICT spending

Taking market share from other media (Google rev )

Inexpensive - advertising paying for many services User revolution context, social nets and relationships are

king

Enterprise horizontal 56 million firms, 1.5 million w/>100 employees, 80,000 with more than 1000

employees

Industry verticals $20M (2000), $3.9B (2007),$50B (2010), $78B (2011)

Semantic web deployment

Geonames - uses Semantic Web data to create adata rich resource of location and geographicinformation

On-demand television service Joost uses RDF topull channel and TV show information

Major companies offer (or will offer) Semantic Webtools or systems: Adobe, Oracle, IBM, HP,Software AG, Northrop Grumman

Some of the names of active participants in W3CSW related groups: HP, Agfa, SRI International,Oracle, Boeing, IBM, Chevron, Siemens, Nokia,Merck, Pfizer, AstraZeneca, and Sun

Benefits

Maximize outsourceability byseparating core IP (information,rules, logic, data, constraints,conditions) from coding procedures.

Extend Intellectual Property tostandard models that can be ownedand maintained locally

Youruse of open standard metadataand rule formats extends thecapability of the semantic net



Business value

Capability

Performance (efficiency,effectiveness, edge)

Life cycle economics



Impact on labor

Will impact professions, management andtechnical ranks

Executable knowledge will become basisfor new categories of research, analysis,

planning, design, diagnosis and decisionmanagement tools

Need knowledge tools for management,accounting, finance, medicine, law,software development, scholarship,hobbies, entertainment, and games

State of the Semantic Web

Remember:

1. The Web was born at CERN

2. was first picked up by high energyphysicists

3. then by academia at large4. then by small businesses and start-ups

5. Big business came only later!

Network effect kicked in early

Semantic Web is now at #4, and movingto #5
