and coherencebased approaches to sentence ranking

... Sentence ranking is a crucial part of generating text summaries. We compared human sentence rankings obtained in a psycholinguistic experiment to three different approaches to sentence ranking: ... rankings (cf. Goldstein et al. (1999), Radev et al. (2002) for that distinction). We evaluated different approaches to sentence ranking against human sentence rankings. To obtain human sentence ... ‘bare-bones’ algorithms is viable because it allows to see how performance differs due to different basic approaches to sentence ranking, and not due to potentially different effects of different...
