Ever since the Internet came into existence, it has been a goal to make information available and accessible free of charge. In the past couple of years, we have witnessed the growing popularity of the Open Data movement and Semantic Web technologies, which have finally made large amounts of data available -- forming the Web of Data. But we are still missing technologies that actually make efficient use of it. Hence, QWeb's main goal is to develop breakthrough technologies based on Semantic Web standards, such as RDF and SPARQL, that overcome this gap and answer user queries easily and efficiently over the Web of Data. In particular, QWeb will not only make it possible to efficiently and extensively evaluate queries and find results that state-of-the-art techniques do not find but also to filter out the results that are most interesting to the user and provide explanations for them.
