SUBJECT: AIC COLLOQUIUM
The Lockheed AI Center is pleased to announce a presentation by
Dr. Peter F. Patel-Schneider of the Schlumberger Palo Alto
Research. An abstract of the presentation is provided below.
Weak, Object-Based Knowledge Representation Systems
Dr. Peter F. Patel-Schneider
Recent work in semantics for terminological logics -- logics
about the relationship between classes -- has demonstrated that
the tradeoff between expressive power and computational
tractability in such logics can be circumvented. This indicates
that tractable object-based knowledge representation systems can
be built, albeit at the cost of weakening deduction. These
systems, because of their tractability, could be used in large
knowledge-based systems. Their representational semantics would
provide a cleaner foundation for object-oriented knowledge-based
systems than do object-oriented programming systems, the systems
currently used to build object-oriented knowledge-based systems.
This cleaner foundation means that fewer complications would
arise in the building and analysis of knowledge-based systems,
thus making these difficult tasks easier.
