My research can be characterized by two sub-areas of Artificial Intelligence, namely knowledge representations and cognitive agents. I investigate representations that allow cognitive agents, assistance systems, or software agents to represent their environment and to reason about it. Dealing with coarse, uncertain, and even conflicting knowledge is of key interest to me. I take a broad interpretation of the term reasoning to encompass all rational tasks required by a cognitive agent, in particular planning and recognition of context, actions, and events as well as learning and deduction. I am developing the spatial reasoning toolbox SparQ and I am likewise interested in beautiful theories and efficient algorithms. So far, I have contributed to these research areas:
- Qualitative spatial and temporal reasoning
- Knowledge representation, symbolic reasoning
- AI robotics, mobile robot localization, mapping, and navigation
- Semantics of natural language, referring expression generation
- Shape retrieval in computer vision

Very simple model but excellent performance—this is my first paper addressing natural language semantics

Developing systems like SparQ is a whole lot of (unpublished) work, but I think it is worth the effort to disseminate results and to link basic research with applications.

Qualitative spatial reasoning can be way harder than expected! Considered by Bernhard Nebel to be the most surprising result of the 2nd funding phase of the spatial cognition research center SFB/TR 8.
