  2. 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 acquisition from text, i.e. a transition from a non-formalized text into a formalized actionable language (i.e. capable of reasoning). • Other steps in the text understanding pipeline include linguistic processing, reasoning, text generation, search, question answering etc. which are more or less solved to the degree which allows composition of a text understanding service. • On the other hand, we know that knowledge acquisition, as the key bottleneck, can be done by humans, while automating of the process is still out of reach in its full breadth.
