Yes, that is the history of the term. AI assumed 
that we needed to get something in our machines 
that served for them the same role that human 
knowledge (or maybe belief) serves (or so it is 
thought) for us humans. To encode that stuff in a 
machine requires that it be 'represented' in some 
way. Hence 'knowledge' + 'representation'.    (02)

Well, AI has never been as sensitive as 
philosophers have been about the distinction 
between knowledge and belief, perhaps because AI 
has never shared philosophy's traditional concern 
with certitude.    (04)
