Section 6 (Related Work) further contrasts our task with summarization.
formally we define our task as follows: given an existing curated text s and a document d describing novel information relevant to that text, the system must produce a revised text s that incorporates the most salient information from d. We restrict our focus to the cases where the revised text s can be obtained by appending the new information from d to the original curated text s. 2 we assume we can transform the old curated text s into the new text s by appending one additional update sentence x to s. This paper operates in a conventional supervised learning setting.
