  2. What is BONy? • Technology enhanced platform for collaborative learning • Semantic technology for • System integration • DOKEOS: Learning Content Management System • Spree: social network • develop advanced functionalities • User Profiling • Expert Finding • Semantic Search • Mentoring: Generation of personalized learning paths • GOAL: make it work!

  3. What is BONy? Project Cycle Management • Italian • Spanish • Polish • Greek • Catalan • France • German • English • Hungarian • Slovak • Czech UNITS Basic Concepts European project cycle European Project Management Methodology Legal aspects Exploitation

  4. What is BONy? BONy Educational Social Network The BONy community Expert Finding Based on http://spree.dai-labor.de/

  5. Semantic Technology in BONy

  6. Principles • Re-usability: • when adapted to a new course, the OWL schema of the ontology is preserved • minimize the adaptation costs to new domains; • Modularity • Topic Ontology • User Ontology • eLearning Ontology • Best practices: • the ontology has been designed by specializing Ontology Design Patters (ODP)

  7. The Bony Ontology

  8. Building the topic ontology • A domain expert manually selected relevant keywords for each English SCO • Looking for corresponding wikipedia pages and their categories • 54TOPICs • KW hasTopic TOPIC • Taxonomy is inspired by the wikipedia hierarchy • Keywords has been translated in all remaining languages

  9. User Profile 1/2

  10. User profile 2/2

  11. What is BONy? BONy Educational Social Network Ask for support / automatic Expert finding

  12. Connecting Users and SCOs • eLearning Ontology: • Describes Shared Content Objects (SCO) • type of electronic support adopted • dependencies between learning objects • time required for learning • SCOhasTopicTOPIC • User Ontology: • Represents user profiles • AGENTknowsTopicTOPIC • 5 Levels of expertise • knowsBasic • … • knowsPerfect

  13. Mentoring: personalized learning paths based on the user profile Implemented by SPARQL queries

  14. Conclusion • Semantic technology has been used for • System integration • Advanced functionalities • BONy 3.0: Knowledge Centric Authoring tool • learning objects are generated from existing Linked Data • Using Ontology design patterns for aggregating Linked Data

  16. Semantic Technology in BONy

  17. Inspiring Principles • re-usability: • when adapted to a new course, the OWL schema of the ontology is preserved • minimize the adaptation costs to new domains; • modularity: • three modules • eLearning content • social network • Topics • best practices: • the ontology has been designed by specializing Ontology Design Patters (ODP)

  18. The Bony Ontology Ontology Design Patterns are used

  19. The BONy ontology • Topic Ontology: • Represents topics covered by the eLearning course • TOPIC broader/narrower than TOPIC • eLearning Ontology: • Describes Shared Content Objects (SCO) • type of electronic support adopted • dependencies between learning objects • time required for learning • SCOhasTopicTOPIC • User Ontology: • Represents user profiles • AGENTknowsTopicTOPIC • 5 Levels of expertise • knowsBasic • … • knowsPerfect

  20. Building the topic ontology • A domain expert manually selected relevant keywords for each English SCO • 46 SCO • Average 5 KWs/SCO • SCO hasKeyword KEYWORD • Find wikipedia pages for each keyword and corresponding wikipedia categories • 54 different TOPIC • KW hasTopic TOPIC • Taxonomy is inspired by the wikipedia hierarchy • Keywords are translated in different languages

  26. Mentoring: personalized learning paths based on the user profile Reasoner implemented by SPARQL query

  27. User Profile 1/2

  28. User profile (1/2)

  29. Multilingual Search Technology: NLP, Lucene

  30. Mentoring • Generation of personalized learning paths • Goal: recommending slides minimizing the • User profile is represented in the same topic space of learning objects • Sparql queries are used to select objects having different topics

  32. Expert finding 2/2

  33. BONy 3.0: project proposal • Knowledge Centric Authoring tool • Linked open data are the building blocks of learning objects • Ontology design patterns for aggregating linked data • Learning objects are dynamically rendered on a variety of media (web pages, PDA, speech) • Agent based services • Automatic generation of questionnaires • Agent assisted tutoring • Semantic social network (Partially in BONy) • From search to recommending • Personalized generation of learning paths (already in BONy) • Related learning objects • Semantic browsing of content
