Human expertise is not found in the sum of explicit practices or algorithms. It's in the experience, mental models and heuristics of individuals. Invisible to current Knowledge Engineering, psychology and (most) linguistics, these 'rules of thumb' are available (can be hacked) through specific pragmatic, syntactic, and semantic 'filters/handles' that can be detected, influenced, and transferred. Applications / instantiations to humans achieved. Computing and human/computer interface applications sought.
