Abstract
This paper presents a new technique for information access based on a combi nation of Geographic Information Systems (GIS) and conceptual structures as modeled in relational concept analysis. it is based on the idea that tradi tional relational databases restrict their data types to linearly ordered s cales. Since spatial data are not linearly ordered, they cannot be modeled directly in relational databases, but require GIS. A Conceptual Query Inter face (CQI) separates the query syntax from conditions for the data types an d presents the data in a conceptual environment. It therefore allows a comm on modeling of linearly ordered and spatial data. Previously CQI has been a pplied to building a graphical interface for faceted thesauri. The main con cern of our modeling of GIS and conceptual structures is not geography, but applications that utilize abstract spaces, such as information spaces, kno wledge spaces or the World Wide Web. We present a graphical interface that allows access of spatial, hierarchical, and linear data in a common manner. We discuss its features and limits.
