Abstract
When dealing with large, distributed systems that use state-of-the-art
components, individual components are usually developed in parallel. As
development continues, the decoupling invariably leads to a mismatch
between how these components internally represent concepts and how they
communicate these representations to other components: representations
can get out of synch, contain localized errors, or become manageable
only by a small group of experts for each module. In this paper, we
describe the use of an ontology as part of a complex distributed virtual
human architecture in order to enable better communication between
modules while improving the overall flexibility needed to change or
extend the system. We focus on the natural language understanding
capabilities of this architecture and the relationship between language
and concepts within the entire system in general and the ontology in
particular.
