Linked Data allows meaningful links to be created between pieces of data on the Web. Adoption of Linked Data technologies has shifted the Web from a space of connecting documents to a global space where pieces of data from different domains are semantically linked and integrated to create a globalWeb of Data. While small amounts of Linked Data can be handled in-memory or by standard relational database systems, big Linked Data graphs, which we nowadays have to deal with, are very hard to manage. Modern Linked Data management systems have to face large amounts of heterogeneous, inconsistent, and schema-free data. The aim of this tutorial is to provide a comprehensive overview of the state-of-the-art in linked data storage techniques, static/streaming query processing mechanisms, scalable reasoning approaches, and benchmarking.
The material of this tutorial is based on the book "Linked Data: Storing, Querying, and Reasoning"
