Semantic Web For Dummies

  1. 1. … a quick introduction to:
  2. 2. What is the Semantic Web? The Semantic Web means different things to different people. (ironic, eh?) Semantic Web for Dummies defines it in the following ways: a) Family of Web standards aimed at making data on the Web easier to use and re-purpose. b) An upgrade to the current Web that marks a new era of intelligence in the applications you use in a Web browser. c) Collection of metadata technologies to improve the responsiveness and adaptability of business software applications. d) Social movement favoring free open-source data that can be linked together, re-purposed or re-mixed e) Web generation of Artificial Intelligence (AI) that builds upon Frame Systems, Semantic Networks and Description Logics f) Controversial vision derided by some people as hyperbole, failed AI technology, and unachievable wishful thinking. …what it isn’t A better search engine….a “Google killer”….or, the Wolfram Alpha An “Ivory Tower” ….dressed up Artificial Intelligence for expert systems HTML tagging language ….competition for Microformats ….Dewey Decimal for the Web A multi-billion dollar software industry (I wish!)
  3. 3. Semantic Web in your life… Idealistic (and controversial): More Down to Earth: • Making our country safer • Making your life simpler • Making our country more prepared for disasters • Fewer mouse clicks to find data; stay organized • Improving the speed we find new medications better on the Web and in your Browser; collect • Unifying disconnected software standards and share your interests easier; organize your • Making business software more change-resilient and travel plans; pinpoint your news content less expensive • Save you time and money • Building the giant database in the sky from open- • Finding online resources easier; preserve source data knowledge better; integrate information; • Giving humanity the gift of open knowledge linking Web services; build mash-ups faster; more targeted advertizing Semantic Web at work for business… Empower new business capabilities with stronger and more • consistent metadata linking, automatic inference for dynamic data DCF Risk Trap! structures, and a more declarative foundation model for shared business information • Throttle back IT expenditures within medium and large businesses with reduced head-count requirements for the management of enterprise information assets, decrease the long-term costs of integration, and simplify decentralized data architectures • Transform enterprise software foundations as major software vendors and standards communities adopt Semantic Web specifications within the context of mainstream tools, applications and infrastructure. (aka: Semantic Web isn’t as risky as you think it is!)
  4. 4. Building the Semantic Web Example: TopBraid Composer Other Semantic Web enablers… often mistaken as Semantic Web: • Natural Language Processing (NLP) – entity extraction • Rule Interchange Format (RIF) – business rules • Theorem Provers, Fuzzy Logics, Production Systems etc. often overlooked in real Semantic Web solutions: • Relational DBs, Java, XML, and mainstream data tools like ETL, Data Profiling and Data Quality
  5. 5. Linked Data Web
