Dirk Walther

Principal Consultant Managing Information and Data Integration

Principal consultant with extensive experience in information modelling and semantic technologies in an industrial context, as well as in the investigation of problems in the areas of artificial intelligence and knowledge representation and reasoning in academia. He is passionate about advising several industry partners across sectors including energy and maritime in developing ontology information models and software prototypes.

About Dr Walther

Dirk is supporting clients and several industry partners across sectors including energy and maritime in developing ontology information models and software prototypes. 

His focus lies in advising several industry partners in the energy and maritime sectors in Norway where he is developed ontology information models and software prototypes to enable efficient data exchange across industry value chains.  Further, he was the editor of the latest working draft of ISO 15926-14 and has contributed to the Part-14 upper ontology. His work has a significant impact on solving key challenges to data interoperability and efficient data exchange, enhancing efficiency and safety across high-risk industries. 

His expertise spans ontology engineering and computer science. In addition to extensive experience working on industry projects, he has published numerous scientific articles in top-ranking international AI journals and conferences, and has presented his work at international conferences and summer schools (Google Scholar: 1479 citations and h-index 17).
