摘要

The already difficult knowledge acquisition process is complicated when the expert system being developed requires interaction with multiple experts. In this tutorial for novice knowledge engineers and managers we discuss some considerations involved in using multiple experts, including (1) deciding when multiple experts may be necessary, (2) eliciting knowledge from multiple experts individually or in small groups, and (3) knowledge engineer capabilities and preparation.
