35. 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)
© Copyright 2008 Dow Jones and Company, Inc. Proprietary and Confidential |
36. OK, so how do I get started?
© Copyright 2008 Dow Jones and Company, Inc.
37. Youâre Already
at the Starting Line and Have Been
in Training for Years!
© Copyright 2008 Dow Jones and Company, Inc. Proprietary and Confidential |
38. âąMetadataâs Evolutionary Path
Controlled Ontologies
Vocabulary
Thesauri
Hierarchical
Taxonomies
Metadata evolves
Structured
User Tags
Authority Files organically â the less
complex metadata elements
form the building blocks for
Dictionaries
& Flat Lists creating the more complex
structures
© Copyright 2008 Dow Jones and Company, Inc. Proprietary and Confidential |
39. Maybe you have a
TaxonomyâŠ
UP
groups things or
DOWN
concepts into
families
Telephones
Is a broader term than
Mobile Phones
© Copyright 2008 Dow Jones and Company, Inc. Proprietary and Confidential |
40. Or a thesaurusâŠ
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
© Copyright 2008 Dow Jones and Company, Inc. Proprietary and Confidential |
41. Work towards an OntologyâŠ
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
© Copyright 2008 Dow Jones and Company, Inc. Proprietary and Confidential |
42. And Why is this Important?
Well you are a HUMANâŠ.
so based on day to day
knowledge you have acquired you
know a âcell phoneâ
IS a âTelephoneâ
© Copyright 2008 Dow Jones and Company, Inc. Proprietary and Confidential |
43. And Why is this Important?
And since you are a HUMANâŠ.
you can probably make the simple
leap that âTelephonesâ ARE made
by âPhone Manufactures'â that
USE the networks âTelecoms
Service Providersâ deliver.
© Copyright 2008 Dow Jones and Company, Inc. Proprietary and Confidential |
45. So If Semantics Equals âMeaningâ
Computers mimics human âtalkâ so
they need to be taught what that
âtalkâ means-
The Semantic Web is about things
(concepts) (people, places, events)
and how they are related
© Copyright 2008 Dow Jones and Company, Inc. Proprietary and Confidential |
46. Taxonomies,
Ontologies ,
Folksonomies
Oh my!
And of course there is much
more you can get started with!

51. Best practices for starting out
Find
Begin with existing schema, vocabularies and datasets.

local use.
Linked Data
