Towards Cognitive Adequacy of Topological Spatial Relations
نویسندگان
چکیده
Qualitative spatial reasoning is often considered to be akin to human reasoning. This, however, is mostly based on the intuition of researchers rather than on empirical data. In this paper we continue our eeort in empirically studying the cognitive adequacy of systems of topo-logical relations. As compared to our previous empirical investigation KRR97], we partially lifted constraints on the shape of regions in con-gurations that we presented subjects in a grouping task. With a high level of agreement, subjects distinguished between diierent possibilities of how spatial regions can touch each other. Based on the results of our investigation, we propose to develop a new system of topological relations on a ner level of granularity than previously considered.

Towards Usable Topological Operators at GIS User Interfaces
The topological relations defined by formal mathematical models like the nine-intersection are not adequate for user interaction. Human subject tests have shown that people rather use less, grouped, and overlapping relations. But these are only first results and a theory for building cognitively adequate operator sets is missing. This is reflected by the considerably different operator sets of ...

Nowadays, geospatial information systems (GIS) are widely used to solve different spatial problems based on various types of fundamental data: spatial, temporal, attribute and topological relations. Topological relations are the most important part of GIS which distinguish it from the other kinds of information technologies. One of the important mechanisms for representing topological relations...
متن کاملThe cognitive adequacy of Allen's interval calculus for qualitative spatial representation and reasoning
Qualitative spatial reasoning (QSR) is often claimed to be cognitively more plausible than conventional numerical approaches to spatial reasoning, because it copes with the indeterminacy of spatial data and allows inferences based on incomplete spatial knowledge. The paper reports experimental results concerning the cognitive adequacy of an important approach used in QSR, namely the spatial int...
متن کاملA Model of Spatial Position Based on Extremal Points
Two sets of fundamental properties which a spatial representation should describe are the position, extent, and orientation of objects, and topological and directional relations between objects. In previous approaches, the formalization of a particular property, such as topological spatial relations, has often been studied as an independent problem. The resulting theories have been elegant and ...
متن کاملApproximate Topological Relations * Eliseo Clementini and Paolino Di Felice
In spatial data models for various applications, such as geographical information systems (GISs), the importance of topological relations is widely recognized. Topology makes very general statements about the structure and the relations of spatial objects. A refinement of topology by means of other geometric aspects can help to bend the various models that have been developed for topological re...
