    1. 1. The Semantic Web: From Research to Reality Liam Ó Móráin 30 Jan 2010
    2. 2. The Web in Perspective 2010 Web n Web 3.0 Web 2.0 Web 1.0 Web 0 5000 Days 5000 Days 1995 2025 User Publish & Subscribe Push & Punish PARTICIPATION
    3. 3. Data INTEGRATION hasn't changed much really; cleverer techniques but bascially a brute-force approach UNDER-THE-HOOD INTEROPERABILITY is aspirational Amateurs not allowed Tiny percentage of users are active contributors User PARTICIPATION is passive The Web in Perspective 2010 Web n Web 3.0 Web 2.0 Web 1.0 Web 0 5000 Days 5000 Days 1995 2025
    4. 4. Web 3.0 (aka Semantic Web) is coming as the marketplace expects and demands it: question is whether it is more of the same market-hyped activity or a truly innovative game-changing phenomenon! Data INTEGRATION that doesn't work INTEROPERABILITY is aspirational Tiny percentage of users are active contributors User PARTICIPATION is passive Amateurs not allowed Data INTEGRATION that works INTEROPERABILITY is intermodal Hugh percentage of users are active contributors User PARTICIPATION is active and productive Amateurs welcomed UNDER-THE-HOOD IT'S A DATA PROBLEM DUMB DATA with LINKED PAGES not LINKED DATA WE NEED SMART LINKED DATA MACHINE READABLE DATA The Web in Perspective 2010 Web n Web 3.0 Web 2.0 Web 1.0 Web 0 5000 Days 5000 Days 1995 2025
    5. 5. Research, Development, & Engineering led INVENTION Market driven INNOVATION SOLVE THE DATA PROBLEM BY CREATING SMART LINKED DATA The Web in Perspective 2010 Web n Web 3.0 Web 2.0 Web 1.0 Web 0 5000 Days 5000 Days 1995 2025

    7. 7. Smart linked data is created by putting structure on text where there is none. There are three main approaches: Folksonomic, Taxonomic, and Ontological Folksonomic classifications: Created by users using “tags” to annotate and categorize content. If enough people “tag” content, the “wisdom of the crowd” identifies concepts. It gives a statistically inferred relationship! Relationships are created which can then be linked across web pages. Folksonomies are relationship light The Web in Perspective 2010 Web n Web 3.0 Web 2.0 Web 1.0 Web 0 5000 Days 5000 Days 1995 2025
    8. 8. Taxonomic classifications: Experts describe a “thing” or concept in a hierarchical tree with parent/child relationships. Hard to merge concepts through trees! Ontological classifications: Are taxonomies with rules and are graph based Lots of possible relationships not just parent/child Concepts can be more easily joined with graphs Ontologies are relationship intensive The Web in Perspective 2010 Web n Web 3.0 Web 2.0 Web 1.0 Web 0 5000 Days 5000 Days 1995 2025
    9. 9. The web of linked data is gathering speed and can be easily traversed from one repository to another The Web in Perspective 2010 Web n Web 3.0 Web 2.0 Web 1.0 Web 0 5000 Days 5000 Days 1995 2025
    10. 10. DERI's research vision is to create advanced technologies enabling the semantic web in a world of interconnected data and knowledge <ul><li>Interconnected
    11. 11. Universal
    12. 12. All encompassing
    13. 13. Enable global and local collaboration
    14. 14. The right information for the right people at the right time </li></ul>DERI's Research Focus
    15. 15. DERI's has a good mix of MNCs, Irish SMEs, and start-ups partners: DERI's Industry Oriented Research
    16. 16. The Web of the future will have a profound impact on people, their lives and the laws governing them Citizen Smarter/Stupider Critical Thinkers/ Plagiarists Connected/Isolated Passive/Active Privacy Corporations & Government A different type of “command & control” collaborate transparency openness Decoupled environment Engaged communities Custodians Entrust Data protection Data privacy Uptake and Commercialization Some areas of thought
