Abstract:
One of the main objects of a successful expert system is to be able to reach a
conclusion by asking a small number of questions. However, this may be a misleading
approach when the cost of answering questions posed by the system varies. When different
questions are associated with different costs, then it is possible a question asking
strategy to be very costly when it focuses only on minimizing the total number of questions.
This paper expands an existing effective question asking strategy and illustrates the development
of a cost effect question asking strategy for Horn clause systems.
