Commonsense Inference in Dynamic Spatial Systems: Epistemological Requirements
We demonstrate the role of commonsense inference toward the modeling of qualitative notions of space and spatial change within a dynamic setup. The inference patterns are connecte...

Spatial Representation and Reasoning for Human-Robot Collaboration
How should a robot represent and reason about spatial information when it needs to collaborate effectively with a human? The form of spatial representation that is useful for robo...
