Topological Augmentation: A Step Forward For Qualitative Partition Reasoning, Matthew P. Dube
Topological Augmentation: A Step Forward For Qualitative Partition Reasoning, Matthew P. Dube
Journal of Spatial Information Science
The current state of the art for partition based qualitative spatial reasoning systems such as the 9-intersection, 9+-intersection, direction relation matrix, and peripheral direction relations is that of the binary set intersection — either empty or non-empty — conveying the intersection (or lack thereof) of an object in the sets deriving the partition. While such representations are sufficient for topological components of objects, these representations are not sufficient for various tasks in qualitative spatial reasoning (composition, representation transfer, converse, etc.) regarding partitions as tiles. Topological augmentation expands the current binary status quo into a system of assigning topological relations between …
