Metadata evolves organically – the less

complex metadata elements form the building blocks for creating the more complex

structures

Maybe you have aTaxonomy…

groups things orconcepts into

families

UP

DOWN

TelephonesIs a broader term than

Mobile Phones

Proprietary and Confidential |© Copyright 2008 Dow Jones and Company, Inc.

SIDEWAYS

Or a thesaurus…that captures the different

names of the family members and explores some

more distant associations

Mobile PhonesAKA as

Cell Phones & Hand SetsAnd Similar to

Hand Held Devices & PDAs

Proprietary and Confidential |© Copyright 2008 Dow Jones and Company, Inc.

Multi-

Directional

Work towards an Ontology…shows a network of

multi-dimensional relationships and properties both within and

outside the family groups

Mobile PhonesAre made by

Phone ManufacturersAnd use the networks of

Telecoms Service Providers

Proprietary and Confidential |© Copyright 2008 Dow Jones and Company, Inc.

And Why is this Important?

Well you are a HUMAN….so based on day to day knowledge you have acquired you know a ‘cell phone’IS a ‘Telephone’

Proprietary and Confidential |© Copyright 2008 Dow Jones and Company, Inc.

And Why is this Important?

And since you are a HUMAN….you can probably make the simple leap that ‘Telephones’ ARE made by ‘Phone Manufactures'’ that USE the networks ‘Telecoms Service Providers’ deliver.

So If Semantics Equals ‘Meaning’

Computers mimics human ‘talk’ so they need to be taught what that ‘talk’ means-The Semantic Web is about things (concepts) (people, places, events) and how they are related

Taxonomies, Ontologies ,

Folksonomies Oh my!

And of course there is much more you can get started with!
