... bears some resemblance to headline generation (Dorr et al., 2003; Banko et al., 2000), although we output sev- eral sentences rather than a single one. Head- line generation models typically extract ... highlights (mean and standard devia- tion). A minority of documents are transcripts of interviews and speeches, and can be very long; this accounts for the very large standard deviation. T...
