The increasing popularity of the Web of Data has over the past years caused a significant increase in the number of open knowledge graphs published on the Web. However, the structure of the Semantic Web today relies totally on the data providers to maintain Web services that provide efficient and scalable access to the knowledge graphs, as well as to keep the data up-to-date.

Without any monetary incentives to do so, publicly available knowledge graphs often become unavailable and outdated, making it difficult to trust the data available in the knowledge graphs. As a remedy, this thesis investigates and addresses the availability, scalability, and updatability issues with the aim of making knowledge graphs on the Web available, scalable, and updatable.
