  • With the invention of the telegraph, wires were run across the United States to carry data (telegrams). The wires were run along existing right-of-ways: the rail networks already carrying people and goods. This is a good analogy for the relationship between the Semantic Web (telegraph) and the Web for people (railways).

  • Open Rubrics and The Semantic Web: Open Ed 2010

    1. 1. Open Rubrics and the Semantic Web Brian Panulla Panulla Information Systems Megan Kohler Pennsylvania State University Open Ed 2010 The Seventh Annual Open Education Conference 2-4 November, 2010 Barcelona, Spain
    2. 2. Open Ed 2010 About Us Megan Kohler msm26@psu.edu Brian Panulla Twitter: @bpanulla (c)2010 Google, Imagery (c)2010 TerraMetrics, NASA, Map data (c)2010 Europa Technologies, Google, INEGI, AND
    3. 3. Open Ed 2010 What is a Rubric? • Education/Teaching instrument • Tries to measure learning ▫ Self-assessment ▫ Evaluation (grading)
    4. 4. Open Ed 2010 Benefits of Rubrics • Consistency in grading • Efficiency in reviewing students’ work • Customized feedback • Scalability for large course sizes
    5. 5. Open Ed 2010 Rubrics on the Web • Presentational formats ▫ PDF ▫ MS Word ▫ Excel ▫ HTML • Difficult to read with software • Proprietary formats ▫ “Walled Gardens” • Limited portability / linkability
    6. 6. Open Ed 2010
    7. 7. Open Ed 2010 Why open rubrics? • Shareable, portable • Machine-readable • Linkable like The Web ▫ Build libraries of feedback / comments • Semantic Web?
    8. 8. Open Ed 2010 Three things the SW is not: 1. Semantic HTML 2. Artificial Intelligence 3. Magic
    9. 9. Open Ed 2010 New W3C Languages ▫ Resource Description Framework (RDF) ▫ RDF Schema ▫ Web Ontology Language (OWL) Yes, rly.
    10. 10. Open Ed 2010 The SW is infrastructure • A parallel information system architecture • Web content, pages do not need to change
    11. 11. Open Ed 2010http://xkcd.com/773/ Semantic Web
    12. 12. Open Ed 2010 Linked Data • Publish/Syndicate complete information sets • Embedded explicit semantics, unique identifiers • Have minimal impact to other Web information publishing • May be static or dynamically generated
    13. 13. Open Ed 2010 Linked Data - 2008 http://richard.cyganiak.de/2007/10/lod/
    14. 14. Open Ed 2010 Linked Data - 2008 http://richard.cyganiak.de/2007/10/lod/
    15. 15. Open Ed 2010 Rubric Ontology • Main classes ▫ Rubric  Analytic, Holistic ▫ Category ▫ Criterion ▫ Level ▫ Scope ▫ Scoring • Main properties ▫ hasCriteria ▫ hasLevels ▫ title ▫ description ▫ benchmark ▫ score ▫ weight ▫ feedback
    16. 16. Open Ed 2010 Rubric Ontology in UML (kinda)
    17. 17. Open Ed 2010 Criterion
    18. 18. Open Ed 2010 Level
    19. 19. Open Ed 2010 Category
    20. 20. Open Ed 2010 Scope and Scoring • Scope of assessed/evaluated work: ▫ Individual ▫ Team ▫ Peer ▫ Self • Scoring mode of the assignment ▫ Scored ▫ Unscored
    21. 21. Open Ed 2010 Integration • Friend of a Friend (FOAF) http://xmlns.com/foaf/spec • Creative Commons RDF http://creativecommons.org/ns • Dublin Core?
    22. 22. Open Ed 2010 Rubric Builder
    23. 23. Open Ed 2010 Rubric Projects • PSU Faculty-Self Assessment for Online Teaching https://weblearning.psu.edu/FacultySelfAssessment • PSU Rubric Module for Drupal 6 @ Drupal.org http://drupal.org/project/rubric • Rubric Ontology http://github.com/bpanulla/rubric-ontology • Rubric Builder (Flex / AIR) – RSN* • Rubric Module for Drupal 7 – design phase * - Real Soon Now

    26. 26. Open Ed 2010
    27. 27. Open Ed 2010 Semantics • Explicit “meaning” of symbols ▫ Words – usage, connotation ▫ Images - symbolism • Become really useful when shared
    28. 28. Open Ed 2010 Differs from Syntax • Rules of how symbols (words, letters, pictures) can be arranged. I love Sushi
    29. 29. Open Ed 2010 Semantics • Can be unchanged despite symbols used I Sushi
    30. 30. Open Ed 2010 Semantics • Can still be misunderstood without context I Sushi, but not in that way. And who or what is “Sushi”?
    31. 31. Open Ed 2010 RDF: Resource Description Framework • Fundamental knowledge representation • Everything is a resource
    32. 32. Open Ed 2010 Triples • RDF is expressed as triples: ▫ subject (“Penn State”) ▫ predicate (”is a") ▫ object (”University”) Penn State University Is a
    33. 33. Open Ed 2010 Triples • Another example: ▫ subject (“Brian Panulla”) ▫ predicate (”presented at") ▫ object (”OpenEd 2010”) Brian Panulla OpenEd10 presented At
    34. 34. Open Ed 2010 Triples to Graphs Brian Panulla OpenEd 2010 Penn State University Is a Portland State City of Portland Held in Spain
    35. 35. Open Ed 2010 Triples to Graphs Penn State University Is a Portland State Is in City of Portland Is in State of Oregon United States of America North America Isin Canada NATO State of Washington State of California Brian Panulla OpenEd 2010 Held in Spain
    36. 36. Open Ed 2010 URIs • Resources are identified by a Uniform Resource Identifier (URI) http://www.psu.edu/owl/ist.owl#CollegeOfIST http://2010.highedweb.org/sessions.rdf#TPR9
    37. 37. Open Ed 2010 RDF Schemas • Think of classes in RDFS as sets rather than OOP classes • RDFS provides limited Set Theory features ▫ subClassOf ▫ subPropertyOf ▫ Domain ▫ Range
    38. 38. Open Ed 2010 Web Ontologies • Ontologies describe meaning or intended use. • OWL adds more expressiveness and many aspects of formal logic to RDF.
    39. 39. Open Ed 2010 Some OWL Features • Classes ▫ Sub-class ▫ Equivalent Classes ▫ Disjoint Classes ▫ Cardinality constraints (max/min) • Individuals ▫ Same Individual • Properties ▫ Sub-property ▫ Equivalent ▫ Inverse ▫ Symmetric ▫ Transitive
    40. 40. Open Ed 2010 Resources • Semantic Web Programming - John Hebeler, Matthew Fisher, Ryan Blace, and Andrew Perez- Lopez • Semantic Web for the Working Ontologist: Effective Modeling in RDFS and OWL -Dean Allemang and James Hendler • Programming the Semantic Web by Toby Segaran, Colin Evans, and Jamie Taylor
