Job description

Semantic Knowledge Graphs are thé way to create interoperable data, which in turn leads to more advanced applications and analytics. However, generating knowledge graphs from existing data is not an easy feat. Existing data is very heterogeneous: differences in volume (small and big), velocity (static and streaming) and variety (different data formats such as JSON, CSV, and XML) result in complex combinations of hard-coded tools, leading to unmaintainable black-box environments. This is why knowledge graph applications are currently reserved for big tech such as Google and Facebook.

The RML Tool Suite provides a one-stop-shop to generate knowledge graphs for any specific domain model from all these heterogeneous data sources using a white-box configurable framework. We lead this research domain with over 8 years of experience and are involved in the standardization process, however, our work is far from done: many research topics are yet to be fully explored, including virtualization of knowledge graphs, automatization of knowledge graph generation, knowledge graph workflows, investigation of performant joining algorithms, etc.

Are you passionate about data, the Web, and interested in working on decentralized knowledge graph technologies? Join our team to work on the next phase of the Web! Under the supervision of a.o. dr. Ben De Meester, expert in high-quality Knowledge Graph generation, you can contribute to bringing knowledge graphs to the masses by tackling knowledge graph generation’s most pressing challenges.
