  abstract = {In this paper we examine 1) the scope of geo-ontologies used especially for the 
purposes of information retrieval on the Web, 2) the core geographical concepts and their mutual relations, and 3) the 
properties the concepts have. Furthermore, we present the Finnish geo-ontology (Suomalainen 
paikkaontologia, SUO) and discuss the theories and principles that have governed the development process, as well as 
the limitations and requirements the use of geographical dictionaries as an instance data source have 
imposed to the content and the structure of SUO.}
