Understanding Linked Data via EAV Model based Structured Descriptions

  1. 1. Demystifying Linked Data Via Entity-Attribute-Value (EAV) Data Model By Kingsley Idehen Twitter ID: @kidehen Founder & CEO, OpenLink Software © 2010 OpenLink Software, All rights reserved.
  2. 2. Presentation Goals <ul><li>Demystify Linked Data </li></ul><ul><li>Demonstrate the unobtrusive nature of Linked Data </li></ul><ul><li>Explore how Linked Data can Work for You! </li></ul>© 2010 OpenLink Software, All rights reserved.
  3. 3. Situation Analysis <ul><li>User-generated content is growing exponentially </li></ul><ul><li>Enterprise & individual connectivity is growing </li></ul><ul><li>The line between the Individual & the Enterprise is blurring </li></ul><ul><li>The discovery & exploitation of Data, Information, and Knowledge remain the ultimate critical success factors </li></ul><ul><li>But there are still only 24 hours in a day! </li></ul>© 2010 OpenLink Software, All rights reserved.
  4. 4. A Few Definitions <ul><li>What is Data ? </li></ul><ul><ul><li>How we express observation </li></ul></ul><ul><li>What is Information? </li></ul><ul><ul><li>How we use Context to perceive observation </li></ul></ul><ul><li>What is Knowledge? </li></ul><ul><ul><li>How we Comprehend what we perceive </li></ul></ul>© 2010 OpenLink Software, All rights reserved.
  5. 5. Understanding Data <ul><li>What is a Data Item (Datum)? </li></ul><ul><ul><li>A Unit (or Object) of Observation </li></ul></ul><ul><li>What is a Structured Data Item? </li></ul><ul><ul><li>An observation expressed in a manner that makes discernible: </li></ul></ul><ul><ul><ul><li>the Referent (Unit or Object of Observation) </li></ul></ul></ul><ul><ul><ul><li>the Characteristics (Attribute=Value Pairs) </li></ul></ul></ul>© 2010 OpenLink Software, All rights reserved.

  7. 7. How We Describe Things <ul><li>The natural process: </li></ul><ul><ul><li>Something (Referent) catches our attention </li></ul></ul><ul><ul><li>We Identify/Name the Referent of interest </li></ul></ul><ul><ul><li>We Identify its Attributes </li></ul></ul><ul><ul><li>We Assign Values to its Attributes </li></ul></ul><ul><li>Descriptor Resources bear Descriptions </li></ul>© 2010 OpenLink Software, All rights reserved.
  8. 8. The Description Process <ul><li>Identify Referent </li></ul><ul><li>Something grabs our attention </li></ul><ul><li>We give the Object or Unit of Observation a Name </li></ul><ul><li>Identify its Attributes </li></ul><ul><li>We use existing Attribute Names or make new ones. </li></ul><ul><li>Assign Values To its Attributes </li></ul><ul><li>Assign values to which may be References (Names) to other Objects </li></ul>Repeat the process for each Attribute <ul><li>Draw Conclusions </li></ul><ul><li>Establish some “Relative Truths” or “Facts” about your observations </li></ul>
