Short info

Professor of Information Systems Development. Head of the Research Group for Intelligent Information Systems (I2S). Focus on intelligent information systems that use AI techniques such as knowledge graphs, ontologies and large language models. Applications for news media and in the public sector.
Research


In recent years, I have investigated uses of knowledge graphs, ontologies, large language models, and related AI techniques in the news domain. A particular interest has been to represent and reason about the different news angles that journalists use to make a situation or event interesting to their audience. Together with students and colleagues, I have implemented these ideas through practical ontology and knowledge graph-driven journalistic knowledge platforms that aim to support working journalists in discovering and presenting newsworthy situations and events. Reliability and ethical use of AI have been central concerns.

My research builds on a long-term interest in how conceptual models can support the development and management of ICT systems. I have worked with visual models of enterprise architecture that show how the different information systems, databases and other technology components in an enterprise are organised. I have also investigated how visual models of information systems can be used to better understand problem domains and describe requirements for new software systems. I have contributed to security requirements engineering by developing conceptual models and visual notations to help identifying and understanding security threats and their countermeasures. I have evaluated these models and notations experimentally and in case studies.

A central realisation from this research is that conceptual models - whether of problem domains, of businesses, or of their information systems - can play a central role in identifying and aligning different stakeholder perspectives. I have therefore investigated the use of ontology as a common basis for identifying stakeholder perspectives and for resolving and integrating them when possible. This work has involved the use of both philosophical ontology to clarify the underlying assumptions of models and modeling languages ​​and formal ontology together with knowledge graphs to represent multi-perspective models in clear and formal ways that can be processed by computers.

Teaching

I give courses in areas such as knowledge graphs, big data, information systems, systems development, research methods, Python programming and basic information technology. In these areas, I have supervised 10 PhDs and Postdocs and more than 50 Master students through to completion.
