We examine the possible use of description logics (DLs) as a knowledge representation and
reasoning system for high-level scene interpretation. It is shown that so-called aggregates …

In this paper, we outline the creation of an Informed Environment, dedicated to urban life
simulation. We propose methods and tools for creating and providing the information …

Spatial structures and spatial reasoning are essential to perception and cognition. Much day-
to-day practical information is about what happens at certain spatial locations. Moreover …

We examine the possible use of Description Logics as a knowledge representation and
reasoning system for high-level scene interpretation. It is shown that aggregates composed …

This paper presents a new architecture for simulating virtual humans in complex urban
environments. The approach is based on the integration of six modules. Four key modules …

Statistical learning approaches, bounded mainly to knowledge related to perceptual
manifestations of semantics, fall short to adequately utilise the meaning and logical …

As part of the Earth Observation Application Development Program (EOADP) program
sponsored by the Canada Space Agency, Lockheed Martin Canada––in partnership with …

In combination with the rapid technical improvements of computers, building large virtual
scenes has become a popular field in computer graphics. Often, within a real reconstructed …

This paper presents a method for reasoning about spatial objects and their qualitative
spatial relationships (eg touches, overlaps etc.) on the basis of a description logic …

This paper presents an original approach to qualitative spatial representation and reasoning
with topological relations based on the use of lattices of relations. This approach has been …
