The PhD defence will be partially digital, in Kristen Nygaards sal (5370), Ole-Johan Dahls hus and streamed directly using Zoom. The host of the session will moderate the technicalities while the chair of the defence will moderate the disputation.
Ex auditorio questions: the chair of the defence will invite the attending audience at Kristen Nygaards sal to ask ex auditorio questions.

Knowledge Graph and LLM: A Vision for Integrated Application in Geoscience
Main research findings
This thesis investigates how we represent and digitise geological knowledge in the era of Artificial Intelligence. Traditional numerical methods fall short of integrating geological data and understanding both explicit and implicit geological knowledge. The goal is to create a model that can represent complex geological knowledge from various sources and support geological interpretations and modelling. The research uses semantic technologies—a way of representing knowledge that machines can understand—to capture and represent complicated information and knowledge. This research captures the complex knowledge of geological faults and uses them as an example of how to model complicated geological concepts into understandable structures for computers. Additionally, a framework is proposed that not only models static geological scenarios but also processes and allows knowledge-driven simulation based on the modelled processes. Such works are crucial for future AI research, where a vast mount of geological data must become more accessible, and computers can follow the given knowledge to perform reasoning to support geological decision-making. The impact of this research stretches across both Geo and IT disciplines, providing a fresh perspective on geological data. It initiated a collaboration between geologists and IT experts for geological information and data management and application.
