Knowledge engineering history: The KEE (Knowledge Engineering Environment) expert-system shell was a product of which company?

Introduction / Context:
KEE (Knowledge Engineering Environment) was a prominent commercial expert-system shell that provided a rich object–rule environment and graphical tools. Knowing the vendor behind KEE helps place it among peers like ART and other shells of the same era.

Given Data / Assumptions:

• The correct vendor name must match one of the provided options exactly.
• We recognize KEE as a commercial product, not an academic prototype.
• Some distractor options are near-miss spellings or other AI companies.

Concept / Approach:
KEE was developed and sold by IntelliCorp. The option text presents “IntelliCorpn,” which is a misspelling in the original choices but clearly refers to IntelliCorp. Because the instructions require choosing exactly from the given options, we must select the provided string that corresponds to IntelliCorp.

Step-by-Step Solution:

Verification / Alternative check:
Historical product catalogs and AI market surveys list KEE under IntelliCorp’s offerings.

Why Other Options Are Wrong:

• Teknowledge: a different AI company; not the KEE vendor.
• Texas Instruments: hardware and software vendor (e.g., Explorer), but not KEE.
• Tech knowledge: malformed distractor.
• None of the above: incorrect because the IntelliCorpn option corresponds to IntelliCorp.

Common Pitfalls:
Being thrown off by the slight misspelling; always match the historically correct vendor to the closest exact option provided.

Final Answer:
IntelliCorpn
