Limited-Information and Constrained-Processing Tasks

Limited-information and constrained-processing tasks are techniques which either limit the time and/or information available to the expert when performing tasks that would normally require a lot of time and information to perform. This provides a quick and efficient way of establishing the key tasks and information used.

An interesting variant of this is the twenty-questions technique. Here the aim is for the expert is to guess something that the knowledge engineer is thinking about (as in the parlour game of ‘animal, vegetable and mineral’). The expert is allowed to ask questions of the knowledge engineer who is only allowed to respond yes or no. As the expert asks each question, the knowledge engineer notes this down. The questions asked and the order in which they are asked give important knowledge such as key properties or categories in a prioritised order.
