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 |

OK, so how do I get started? © Copyright 2008 Dow Jones and Company, Inc.

You’re Already at the Starting Line and Have Been in Training for Years! © Copyright 2008 Dow Jones and Company, Inc. Proprietary and Confidential |

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

Maybe you have a Taxonomy… 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 |

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

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

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

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

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

Taxonomies, Ontologies , Folksonomies Oh my! And of course there is much more you can get started with! © Copyright 2008 Dow Jones and Company, Inc. Proprietary and Confidential |

STOP! Take Baby-steps. © Copyright 2008 Dow Jones and Company, Inc.

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

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