Figure 5.2: Knowledge Engineers’ Roles in Interactive
Computer-based Knowledge Acquisition

This use of interactive computer-based elicitation can be combined with manual elicitation and
with the use of the interactive tools by the knowledge engineer rather than, or in addition to, the
expert. The knowledge engineer can:

 Directly elicit knowledge from the expert.
 Use the interactive elicitation tools to enter knowledge into the knowledge base.
Figure 5.2 shows multiple knowledge engineers since the tasks above may require the effort of
more than one person, and some specialization may be appropriate. Multiple experts are also
shown since it is rare for one person to have all the knowledge required, and, even if this were
so, comparative elicitation form multiple experts is itself a valuable knowledge elicitation
technique.
Figure 5.2 also shows the complexity of the knowledge engineer’s role and some of the support
tools required. Figure 5.3 groups the support tools for editing, display, encoding, and validation
of the knowledge bases into a Knowledge-Based System Support Environment and combines
the various forms of knowledge bases together. It shows the overall structure of a
