Job Description

Artificial Intelligence (AI) is one of the central pillars of Industry 4.0 and Internet of Things in the global trend towards smart and highly-digitalized factories. An important approach here is to use symbolic AI, including ontologies or semantic Digital Twins, to represent experts’ knowledge, physical equipment and processes as unified conceptual Semantic Models. They in turn allow to integrate heterogeneous industrial data as uniform Knowledge Graphs. On top of ontologies and Knowledge Graphs, one can develop a wide range of AI solutions for production simulation, process monitoring, analytics and optimization. This can be achieved by combining symbolic reasoning and numeric AI methods, like Machine Learning, in hybrid AI solutions. Bosch Center for AI is active in developing such novel hybrid AI methods and systems and also in applying them in Bosch factories.

The purpose of this PhD research project is to develop novel techniques and systems for Dataset Search over collections of Semantic Models including ontologies and Knowledge Graphs. This in particular requires to develop methods for computing Knowledge Graphs summaries that enable a better end-user comprehension of these semantic artifacts. That is, such summaries should take into account user’s preferences, representative components of the artifacts, as well as their frequent patterns and other important aspects. Search and summarization of ontologies and Knowledge Graphs in the context of Industry 4.0 allow for research topics that range from foundational to applied and give a great opportunity to do top-tier research and publish at top-tier venues as well as to test and evaluate novel techniques and methods in real industrial scenarios of Bosch.

PhD candidates will enjoy top quality inspiring research in an enthusiastic international environment of researchers, other PhD candidates, and industrial professionals from Bosch and its partners, in particular from the SIRIUS research centre at the University of Oslo.
