Abstract

Modeling human concepts of object locations is essential for the development of the systems and machines that collaborate with ordinary people on spatial tasks. This paper applies a heterogeneous cardinal direction model, called HCDM, to model human concepts of object locations on a plane, using its ability to illustrate where and how an object is located as seen from another with different spatial extensions. For generality, we adopt a set of formal spatial concepts defined in an existing spatial ontology called GUM. These location concepts are associated with the patterns distinguished by HCDM. We also discuss the special features of our modeling approach and compare it with the modeling of location concepts by other cardinal direction models.
