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!
