Primary fields of research

My research investigates the philosophical foundations of knowledge organization and information science. My focus is on the enduring tension between universalist or technological approaches to classification and the socially constructed, context-dependent nature of knowledge. The work critically examines how underlying assumptions about reality and meaning shape the design and function of information systems.

The theoretical core of my work integrates pragmatic semiotics, particularly the Peircean tradition, with the domain-analytic framework. This combination provides a robust methodology for analyzing how information is signified and how meaning is negotiated within specific historical, cultural, and epistemic communities. It treats knowledge not as a static collection of facts, but as a dynamic, continous and fallible process of interpretation.

The approach is applied to critically examine a range of knowledge systems, from traditional library classifications and phenomenon-based structures to the automated processes in contemporary artificial intelligence. The research explores how these systems represent, or misrepresent, the complexity of knowledge and the pluralism of human discourse.

The ultimate goal is to develop epistemologically sound and ethically responsible principles for designing information systems. This involves moving beyond technical optimization to create frameworks that are philosophically transparent, context-aware, and capable of supporting the dynamic and contested nature of human meaning-making.
