What was the original criticism of semantic networks?
Answer: D
Early networks used links whose meaning varied between systems and sometimes within one, so what a diagram entailed was unclear. Giving them a translation into first order logic settled the matter and showed they were a notational variant of a fragment of it. Relations were exactly what they represented, and memory and scale were practical issues. A representation whose inferences cannot be stated precisely cannot be debugged, which is why formal semantics matters even for an informal looking notation.
