While much work in summarisation has concentrated on multi-document summarisation, where the main challenge is the detection of redundant information, the summariser presented here is a single-document summariser.
researchers have been attracted by deeper, more symbolic and thus more explanatory summarisation models that use semantic representations of some form (Radev and McKeown, 1998) and often rely on explicit discourse modelling (Lehnert, 1981;Kintsch and van Dijk, 1978;Cohen, 1984).
