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. 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

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. 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
