The tutorial covers conceptual foundations and practical examples of knowledge graphs and rich semantic search. A tension exists in the aim to harness semantic search for integrated data: a shallow common model hides the riches, whereas a rich model complicates the search task. In this tutorial we show how a user-friendly search system can be quickly constructed allowing access into a knowledge graph without compromising the underlying rich semantics of the component datasets.
The audience will learn how to apply the techniques in any application domain, however examples will be given for the cultural heritage domain. This is exemplified using the ResearchSpace project which brings together heterogeneous data from museums and archives. The ResearchSpace solution is based on the agile and modular development capabilities of the metaphacts platform, featuring end-user interfaces for expressing complex information needs, exploration, interrogation and visualization of rich knowledge graphs. The tutorial will cover:
- An introduction to knowledge graphs
- Concepts and techniques for semantic search over rich knowledge graphs
- Hands-on examples and exercises over a cultural heritage knowledge graph
- Application to knowledge graphs in other application domains
Peter Haase founded metaphacts in October 2014. He has 20+ years of IT experience, with 14+ years in semantic technologies, academia as well as industry. In 2006, Peter obtained his PhD from the University of Karlsruhe (now KIT) under the supervision of Prof. Rudi Studer. Lastly, he worked as Head of Research and Development at fluid Operations AG. Previously, he also worked for IBM in the Silicon Valley Labs in the development team of DB2, as well as for the Fraunhofer Institute for Computer Graphics. Peter has acquired and managed numerous large research projects and also led the development of commercial products and solutions in the area of semantic technologies.
