This is by no means a trivial process. Any GOFAI researcher can describe how, in 
principle, one can construct (some) complex cognitive models manually, but inferring 
what the right cognitive model might be on a particular occasion is a complex process,

The CYC example Romeo and Juliet is compelling in that the inferences the system 
derives are sophisticated and sensible, but disappointing in that the underlying model 
is hand-coded, rather than induced from a script of the play. That makes the system fine 
for demonstration purposes, but in the real world, for cognitive models to pave the way 
to robust artificial intelligence, we to find ways of inferring them from streams of data 
(such as video or texts) automatically.
