Context after the citation:
However, our study differs in several important respects. Barzilay and Lee employed an unsupervised approach to building topic sequence models for the newswire text genre using clustering techniques. In contrast, because the discourse structure of medical abstracts is welldefined and training data is relatively easy to obtain, we were able to apply a supervised approach. Whereas Barzilay and Lee evaluated their work in the context of document summarization, the fourpart structure of medical abstracts allows us to conduct meaningful intrinsic evaluations and focus on the sentence classification task.
