- ABSTRACT
-
- The seminar explores the advantages of a marriage between a
- ``mixed dialogue'' interaction metaphor and belief logics
- and in particular how the two can be used for multiple
- inheritance hierarchy design. The result is a design aid
- which produces critiques of multiple inheritance hierarchies
- in terms of their logical consequences. The work draws on a
- number of theoretical issues in artificial intelligence,
- namely belief logics and multiple inheritance reasoning,
- applying ``belief sets'' to dialogue and using multiple
- inheritance hierarchy design as a specific application.
-
- The work identifies three design modes for the interface
- which reflect the intuitions of multiple inheritance hierar-
- chy design and conform to an existing framework for user
- modeling. A major survey of multiple inheritance hierar-
- chies leads to the allocation of a precise inheritance
- semantics for each of these design modes. The semantics
- enable a definition of network entailment in each, and are
- in turn used to determine the translation from inheritance
- networks to belief sets.
-
- The formal properties of belief sets imply that when an
- ambiguous inheritance network is encountered more than than
- one belief set must be created. Each belief set provides an
- alternative interpretation of the logical consequences of
- the inheritance hierarchy. A ``situations matrix'' provides
- the basic referent data structure for the system we
- describe. Detailed examples of multiple inheritance con-
- struction demonstrate that a significant design aid results
- from the explicit representation of operator beliefs and
- their internalization using an epistemic logic.

- Wales. Enter off Botany Street, stop at gate and
- ask grey men for day pass and instructions. Park
- in the main car park on your left. The Samuels
- building is the gray building directly behind the
- gates with strange shield-like objects over the
- windows.
