... disadvantage of extraction- based approaches is the poor linguistic coherence of the extracted summaries. Because of the widespread and well-developed use of sentence extractors in summarization, ... measure, the importance of a node is a combination of its direct importance and of the importance of its children. The parameter α may be adjusted to vary the relative weight of...
