지식을 어떻게 추출할 것인가 ?

배경 Text understanding is an old yet-unsolved AI problem

consisting of a number of nontrivial steps. The critical step in solving the problem is knowledge acqui-

sition from text, i.e. a transition from a non-formalized text into a formalized actionable language (i.e. capable of rea-soning).

Other steps in the text understanding pipeline include lin-guistic processing, reasoning, text generation, search, ques-tion answering etc. which are more or less solved to the de-gree which allows composition of a text understanding ser-vice.

On the other hand, we know that knowledge acquisition, as the key bottleneck, can be done by humans, while automat-ing of the process is still out of reach in its full breadth.
