	<p>Semantic Technologies are a family of recently emerged technologies particularly well suited for managing and sharing large volumes of heterogeneous, rapidly evolving data. This course  is an introductory course covering the Semantic Web languages RDF(S), OWL, and SPARQL. The course is a combination of lectures covering both practical and theoretic aspects of the aforementioned languages and extensive hands-on sessions on modelling and querying semantic knowledge bases. The book ``A Semantic Web Primer'' by Frank van Harmelen and his group  will be used as a course text book. In our hands-on sessions, we use the ontology editor Protege and the SPARQL query engine StarDog.
<h4>Frequency</h4>
<P>This subject has been discontinued; no further courses are planned.</P>
</p>

<h4>Objectives</h4>
<p><p>By the end of the course, students are expected to have acquired the following skills:</p>
<ul>
<li>Solid understanding of capabilities and&nbsp; limitations of RDF(S), OWL and SPARQL</li>
<li>Ability to effectively apply those languages to model relevant aspects of the domain and query semantic knowledge bases</li>
<li>Ability to keep track of&nbsp; the consequences of modeling decisions and to determine modeling alternatives that enable effective querying of the corresponding knowledge base</li>
<li>Awareness of the trade-off between the expressivity of modeling languages and the computational efficiency of querying</li>
</ul></p>
