Scale in Object and Process Ontologiesly different theories of formal ontology such as mereology and granular partitions, and ideas derived from hierarchy theory. These theories are applied to objects and processes and form the framework within which we present tentative definitions of scale, which are found to differ between the two ontologies.

Systematic Distortions in Cognitive Maps: The North American West Coast vs. the (West) Coast of Isray conducted along the (West) coast of Israel. These results suggest that the experiments, on the basis of which the above two forms of systematic distortions were determined, could have resulted from another form of systematic distortion that we term the ..

Tripartite Line Tracks Qualitative Curvature Informatione these shapes show salient visual differences. It turns out that the distinction between two sides of a line together with the distinction between acute and obtuse angles make up a powerful concept of orientation information for shapes in two dimensions.

Intuitive Modelling of Place Name Regions for Spatial Information Retrievalrete approximations of place name regions. Based on knowledge about cognitive aspects of preferred spatial models, our approach allows for the representation and intuitive modelling of indeterminate regions in addition to regions with well-known boundaries.

Convexity in Discrete Spaceers also provide valid notions of convexity in particular contexts. Finally, algorithms are investigated to validate the sets of a matroid, and to compute the convex hull of a subset of an oriented matroid.

Desiderata for a Spatio-temporal Geo-ontologya fully spatio-temporal geo-ontology which can do justice to those phenomena. Such a geo-ontology must (a) provide suitable forms of representation and manipulation to do justice to the rich network of interconnections between field-based and object-based views of the world; (b) extend the field-bas

Scale in Object and Process Ontologiesective on the concept of scale by considering it within two complementary ontological views. The first, called SNAP, recognizes enduring entities or objects, the other, called SPAN, perduring entities or processes. Within the meta-theory provided by the complementary SNAP and SPAN ontologies, we app
