The goal of the semantic web is to make the information available on the web easier accessible. Its idea is to provide machine readable meta-data to enable the development of tools that support users in finding the relevant data. The goal of the thesis is to shed some light onto different foundational aspects of optimization tasks occurring in the field of the Semantic Web. Examples include the redundancy elimination in RDF data or static query analysis of (well-designed) SPARQL queries. Towards this goal, we already contributed several results.
