Although many real world phenomena are vague and characterized by having uncertain location or vague shape, existing spatial data warehouse models do not support spatial vagueness and then cannot properly represent these ...

The phenomenon of vagueness has been studied for centuries and is detected, among other characteristics, for creating the Sorites paradox. Vagueness is identified when we face the lack of precise limits of terms (or their ...

Spatial vagueness has been required by geoscientists to handle vague spatial objects, i.e., spatial objects that do not have exact locations, strict boundaries, or sharp interiors. However, there is a gap in the literature ...

This paper studies how agents choose to be vague in their proposals in a delegation environment. Two agents compete for the approval of a decision maker to implement a multidimensional action. Based on their knowledge of ...

Geographic information systems with the aid of spatial databases store and manage crisp spatial data (or exact spatial data), whose shapes (boundaries) are well defined and have a precise location in space. However, several ...
