The OntoGeo group was formed by Professor Marinos Kavouras in 2001 as an effort to encourage research in Geographic Information Science by researchers, undergraduate and postgraduate students of the School of Rural and Surveying Engineering, of the NTUA.

Current research interests of the group include theoretical topics such as:

• Theories of Concepts in Geography,
• Geographic Categories,
• Concept Mapping,
• Ontological Vagueness,
• Spatio-temporal Modelling and,
• Similarity and Granularity in Geography,

as well as implementation issues such as:

• Formal Ontologies,
• Ontological Engineering,
• Ontology Integration,
• Semantic Interoperability,
• Formal Concept Analysis and
• Concept Lattices.

The members of the group participate in international workgroups and committees, present ongoing work in conferences and publish in journals, in a way to contribute in the state-of-the-art in the field of Geographic Information Science.
