ABSTRACT
Conclusion A One of the key ideas we have extolled in this book is that knowledge repre sentation can play a fundamental role in attempting to build computational models of cognition. We believe that the way a character represents its knowledge is important precisely because cognitive modeling is (currently) such a poorly defined task. If a grand unifying theory of cognition is one day invented then the solution can be hard-coded into some computer chips and our work will no longer be necessary. Until that day, general purpose cognitive models will be contentious or nonexistent. It would therefore seem wise to be able to represent knowledge simply, explicitly, and clearly. If this is not the case then it may be hard to understand, explain, or modify the character’s behavior.
