... iso- lated texts, to the problem of segmenting parallel parts of documents. The task of aligning each sentence of an abstract to one or more sentences of the body has been studied in the context of summarization ... has mostly fo- cused on the linear segmentation of isolated texts (e.g., (Hearst, 1994)). The most straightforward approach would be to use a pipeline strategy,...
