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

Social Network
Connecting Users and SCOs• eLearning Ontology:
– Describes Shared Content Objects (SCO)• type of electronic support adopted• dependencies between learning objects• time required for learning
– SCO hasTopic TOPIC• User Ontology:
– Represents user profiles– AGENT knowsTopicTOPIC– 5 Levels of expertise
• knowsBasic • …• knowsPerfect
Mentoring: personalized learning paths based on the
user profile
Implemented by SPARQL queries
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

Semantic Technology in BONy
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)
The Bony Ontology
Ontology Design Patterns are used
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
– SCO hasTopic TOPIC• User Ontology:
– Represents user profiles– AGENT knowsTopic TOPIC– 5 Levels of expertise
• knowsBasic • …• knowsPerfect
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

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
