KAMET II: An Extended Knowledge-Acquisition Methodology

Reducing the gap between experts' knowledge and data: The TOM4D methodology

“…However, relating both models presents a first difficulty which lies in the different natures of the representation formalisms used in KE and KDD. Diverse KE methodologies and tools such as Roles-Limiting Methods and Generic Tasks [23], and later, CommonKADS [1,2], Protégé [3], MIKE [4,5], KAMET II [6,7], VITAL [8], etc. take as input experts' knowledge and produce as result a model of this knowledge being represented by frames, diagrams, related concepts, logic sentences, etc.…”

“…On one hand, since there are at least two known values associated to x 9 , an unknown value symbol ϕ 9 would not be a priori necessary; but, the need of using ϕ 9 arises when this function must associate two unknown input values ϕ 7 and ϕ 8 with another unknown output value, as shown in Expr. (7). On the other hand, defining the function f 6 from the rules (R 7 ), (R 8 ) and (R 9 ) presents a problem: for a same combination of values in Δ x7 Â Δ x 8 , there are two different values in Δ x 9 .…”

“…( 5) and f 6 in Expr. (7) have to be redefined. Thus, the possible values that x 9 can take are values belonging to Δ x 9 ¼ Iworks; ϕ 9 f g and f 6 is redefined in Expr.…”
