  • Ontologies, ontology design, transformation, and refactoring


  • This module focuses on three main aspects: (i) presenting a number of existing ontologies such as DOLCE, FOAF, SKOS, and ontology design patterns, (ii) showing how to design ontologies by reusing existing resources and transforming them, (iii) showing how to use ontologies in CMS applications e.g for semantic mash-up.

Structure of Contents

  • Analysis of existing ontologies and their usage on Linked data
  • Ontology design patterns
  • Ontology design based on patterns, and refactoring of ontologies through Semion rules
  • Using ontologies for building semantic applications based on IKS.

Previous Knowledge and Requirements

  • Knowledge on RDF, OWL2, and ontology editors
  • Knowledge on SPARQL

Educational Objectives

  • Providing students with the capability of designing ontologies, writing transformation rules, and developing semantic applications for CMS based IKS technologies.

Contents of examination

  • Interactive exercise: assessment of knowledge about popular ontologies, capability to design an ontology, capability to write transformation rules, knowledge about IKS services for managing ontologies and rules.
