As part of the W3C Semantic Web initiative standards and technologies have been developed for machine-readable exchange of data, information and knowledge on the Web. These standards and technologies are increasingly being used in applications and have already led to a number of exciting projects (e.g. DBpedia, semantic wiki or commercial applications such as schema.org, OpenCalais, or Google's KnowledgeGraph). The module provides a theoretically grounded and practically oriented introduction to this area.
The topics discussed within the lecture include:
• History of the Web and Semantic Web
• RDF syntax and data model;
• RDF Schema and formal semantics of RDF(S);
• Ontologies in OWL and formal semantics of OWL;
• RDF databases, triple and knowledge stores, query languages;
• Linked Data Web and Semantic Web applications;
• Semantic text analysis and information retrieval systems.
Good knowledge of database systems theory and practice
