A Taxonomy for Spatial Vagueness An Alternative Egg-Yolk Interpretation
نویسندگان
چکیده
Many of the spatial attributes in our everyday contexts are vague – imprecise and indeterminate. Imprecision is intrinsic (such as indefinite boundaries for certain regions) or situational (such as imprecise location information due to ignorance or inherent errors/imprecision in measuring devices). Even though qualitative representations have an intrinsic facility to handle indefinite and imprecise information, specific formalisms have been developed to facilitate representing and reasoning under such vagueness. The notion of an ‘egg-yolk’ structure underlies most of these formalisms. We propose an alternative interpretation for the ‘eggyolk’ and provide a taxonomic classification of spatial vagueness evolving over time for geographic space.

Definition and implementation of vague objects ?
Vagueness occurs often in spatial information. A concept is vague if objects exist that cannot be classified either to the concept or to its complement. Vagueness arises in the presence of borderline cases. Examples are soil maps, geological maps, forestry inventories, and vegetation maps. Soil classes, or vegetation classes are such that they cannot be defined sharply. The change from one clas...
متن کاملFrom the Egg-Yolk to the Scrambled-Egg Theory
The way we deal with space in many everyday situations is on a qualitative basis, allowing for imprecision in spatial descriptions when we interact with each other. This is often achieved by specifying the spatial relations between the objects or regions that we talk about. In artificial intelligence, a variety of formalisms have been developed that deal with space on the basis of relations bet...
متن کاملSpatial data methods and vague regions: A rough set approach
Uncertainty management has been considered essential for real world applications, and spatial data and geographic information systems in particular require some means for managing uncertainty and vagueness. Rough sets have been shown to be an effective tool for data mining and uncertainty management in databases. The 9-intersection, region connection calculus (RCC), and egg-yolk methods have pr...
متن کاملSpatio-temporal Reasoning for Vague Regions
This paper extends a mereotopological theory of spatiotemporal reasoning to vague ”egg-yolk” regions. In this extension, the egg and its yolk are allowed to move and change over time. We present a classification of motion classes for vague regions as well as composition tables for reasoning about moving vague regions. We also discuss the formation of scrambled eggs when it becomes impossible to...
متن کاملApproximate 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...
