Semantic Web

General

Educational goals

The purpose of the course is to give students a comprehensive view of Semantic Web by focusing on Semantic Web technologies that have reached a certain level of maturity and acceptance, particularly the Resource Description Framework (RDF) and Web Ontology Language (OWL). Upon completion of the course students should have sufficient experience in these technologies and be able to:

  • be familiar the basic technologies of RDF, RDF Schema, Linked Data, ontologies, SPARQL and existing application categories,
  • distinguish/appreciate the reasons for expanding web technologies with semantic models, ontologies and inference systems,
  • produce/describe ontologies in particular domains, implement them and use them with Protégé,
  • analyze how Semantic Web allows new and unexpected uses of available data,
  • create Semantic Web applications using the Jena API and Virtuozo,
  • support the basic logical principles governing Semantic Web technologies.
General Skills
  • Search, analyze and synthesize data and information, using the necessary technologies
  • Decision making
  • Independent work
  • Teamwork
  • Exercising criticism and self-criticism
  • Promoting free, creative and inductive thinking
