Integrating Bipolar Fuzzy Mathematical Morphology in Description Logics for Spatial Reasoning
Bipolarity is an important feature of spatial information, involved in the expression of preferences and constraints about spatial positioning or in pairs of opposite spatial relat...

Computational Structure in Three-Valued Nearness Relations
The development of cognitively plausible models of human spatial reasoning may ultimately result in computational systems that are better equipped to meet human needs. This paper e...

Double-Crossing: Decidability and Computational Complexity of a Qualitative Calculus for Navigation
Abstract. The Double Cross calculus has been proposed for the purpose of navigation based on qualitative information about spatial configurations. Up until now, however, no result...

Relation Algebras and their Application in Temporal and Spatial Reasoning
Qualitative temporal and spatial reasoning is in many cases based on binary relations such as before, after, starts, contains, contact, part of, and others derived from these by r...
