Web 3.0 - Semantic Web Basics

  1. 1. Web 3.0Structured Data Paving The Way<br />WAW Dubai<br />Episode 3 – April 14, 2010<br /><br />
  2. 2. Why Structured Data?<br />Gives meaning to strings of letters <br />Establishes relationships between objects <br />Helps in decision making<br />
  3. 3. Analytics/Search-Friendly Sites<br />Almost everything happens after users login<br />Each user categorizes themselves (sex, age, country, political views, etc) <br />Actions categorized (upload photo, change status, use application etc…)<br />
  4. 4. Analytics/Search-Friendly Sites<br />Number of views, comments, favorites help identify popular videos <br />Percent viewed of video determine stickiness <br />Tags determine content categorization <br />
  5. 5. Analytics/Search-Friendly Sites<br />Sales of items<br />Reviews (and the number of reviews) <br />Ratings<br />
  6. 6. How Do You Extract Meaning From This Text?<br />I live in Dubai, United Arab Emirates. I work at XYZ Inc. which sells products and services. <br />
  7. 7. You Tag it with “Microformats”<br />I live in<div class="adr">  <span class="locality">Dubai,</span><br />  <span class="country-name">United Arab Emirates</span><br /> </div><br />I work at <div class="org">XYZ Inc.</div>which sells products and services. <br />
  8. 8. It’s much easier to make sense of the text<br />“Dubai” is now a locality<br />“United Arab Emirates” is a country<br />“XYZ Inc.” is an organization <br />
  9. 9. Relationships<br />Link to other people in a “meaningful” way<br />Embed information about the linked person to inform the site / search engine<br />
  10. 10. hCard<br />What search engines and other sites see<br />What users see<br />Similar to vCards<br />
  11. 11. The Result<br />Snippets of meta data about search results, make it easier for users to decide<br />
  12. 12. Conclusion<br /> 3 extra minutes of tagging an article can potentially multiply its effect, reach, and importance<br />
