this?
Where can I learn more?
Where can I see it in action?

Survey Question #2

2) If approaches to Semantic web are being
discussed in your enterprise who are they
being driven by?
a. Executives (top down)
b. Technology
c. Users
d. Other (free form field)


OK, so how do I get started?


You’re Already
at the Starting Line and Have Been
in Training for Years!


•Metadata’s Evolutionary Path

Controlled Ontologies
Vocabulary
Thesauri
Hierarchical
Taxonomies

Metadata evolves
Structured
User Tags
Authority Files organically – the less
complex metadata elements
form the building blocks for
Dictionaries
& Flat Lists creating the more complex
structures


Maybe you have a
Taxonomy…
UP
groups things or
DOWN
concepts into
families

Telephones
Is a broader term than
Mobile Phones


Or a thesaurus…
that captures the different
names of the family
SIDEWAYS
members and explores some
more distant associations
Mobile Phones
AKA as
Cell Phones & Hand Sets
And Similar to
Hand Held Devices & PDAs

Work towards an Ontology…
shows a network of
Multi-
multi-dimensional relationships
Directional
and properties both within and
outside the family groups

Mobile Phones
Are made by
Phone Manufacturers
And use the networks of
Telecoms Service Providers

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’


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!

STOP! Take Baby-steps.


Best practices for starting out

Find
Begin with existing schema, vocabularies and datasets.
Re-Use
Use or transform an existing taxonomy or thesaurus.
Use, add or remove elements from an existing schema for
local use.
Linked Data
Open Data
Licensed Data
Publish
Publicly or privately, make your work available to your
intended community or you won’t get to linked data.
Engage subject matter experts
Editorial, Technical and Knowledge Domain

Survey Question #3

3) Are the biggest challenges to starting to
use the Semantic Web / Semantic
Technologies in your enterprise, technology
based or business value/opportunity based?
a. Technology-based
b. Business value/opportunity-based
c. Other (free form field)
