Qualitative Spatial Reasoning Using Algebraic Topology
Many propositions in spatial and qualitative reasoning can be modelled as regions in phase or con guration spaces Deciding the consistency of k propositions then amounts to deciding the question of whether there exists a point which simultaneously falls into all k corre sponding regions A more di cult problem is to decide whether there is a point which falls only within the given k regions I ca...
متن کاملQualitative Spatial Reasoning Using Real Algebraic Geometry
Commonsense reasoning is a major challenge in Artificial Intelligence (AI). As qualitative descriptions comprise a great deal of our everyday language, commonsense reasoning is concerned with developing and processing such qualitative representations. This applies especially to commonsense reasoning about space, where spatial objects are in particular characterized by their spatial relations to...
متن کاملMINIMA: A Symbolic Approach to Qualitative Algebraic Reasoning
The apparently weak properties of a qualitative algebra have lead some to conclude that we must turn instead to extra-mathematical properties of physical systems . We propose instead that a more powerful qualitative algebra is needed, one that merges the algebras on signs and reals . We have invented a hybrid algebra, called Q1, allows us to select abstractions intermediate between traditional ...
متن کاملAn Algebraic Approach to Extend Spatial Operations to Moving Objects
Early Geospatial Information Systems (GIS) dealt with static objects. There is much demand, however, to include temporal objects in these systems. Many have studied this problem and suggested technical solutions for different spatial operations. A common shortcoming is that the extension techniques are highly dependent on the specific case studies and cannot be generalized. In this paper, we pr...
متن کاملnon-corrective approach to pronunciation
the aim of this study has been to find answers for the following questions: 1. what is the effect of immediate correction on students pronunciation errors? 2. what would be the effect of teaching the more rgular patterns of english pronunciation? 3. is there any significant difference between the two methods of dealing with pronuciation errore, i. e., correction and the teaching of the regular ...
