Behavioural indices of qualitative change in children's spatial and computation reasoning strategies

Qualitative Spatial Reasoning

Physical space has unique properties which form the basis of fundamental capabilities of cognitive systems. This paper explores some cognitive aspects of perception and knowledge representation and explains why spatial knowledge is of particular interest for cognitive science. It is suggested that Ôspatial inference enginesÕ provide the basis for rather general cognitive capabilities inside and...

Imprecise Qualitative Spatial Reasoning

This paper addresses the issue of qualitative reasoning in imprecise spatial domains. In particular, the uncertainty in the nature of the spatial relationships between objects in space is represented by a set of possibilities. The approach to spatial reasoning proposed here is carried out in three steps. First, a transformation is carried out on the disjunctive set of possible relationships to ...

Qualitative Spatial Reasoning

Approximate qualitative spatial reasoning

Qualitative relations between spatial regions play an important role in the representation and manipulation of spatial knowledge. The RCC5 and RCC8 systems of relations, used in the Region-Connection Calculus, are of fundamental importance. These two systems deal with ideal regions having precisely determined location. However, in many practical examples of spatial reasoning, regions are repres...

Qualitative Spatial Representation and Reasoning

The need for spatial representations and spatial reasoning is ubiquitous in AI – from robot planning and navigation, to interpreting visual inputs, to understanding natural language – in all these cases the need to represent and reason about spatial aspects of the world is of key importance. Related fields of research, such as geographic information science (GIScience) [71], have also driven th...
