Efficient querying of distributed linked data
Martin Svoboda, Irena Mlýnková · 2011
The contemporary Web is formed mainly by documents, from which it is rather complicated to automatically retrieve hidden structured and interlinked information. The idea of Linked Data based primarily on RDF data triples seems to successfully follow this drawback. In recent years, a significant effort was made not only in a theoretical research, but also in the amount of Linked Data globally available. Since RDF triples are modelled as graph data, we cannot directly adopt the existing solutions from relational databases or XML technologies. Thus, several research questions remain opened.
