We argue that in general, the analysis of lexical co- hesion factors in a document can drive a summarizer, as well as enable other content characterization tasks. More narrowly, this paper focuses on how one particular cohesion factol~simple lexical repetition--can enhance an existing sentence extraction summarizer, by enabling strategies for overcoming some particularly jarring end- user effects in the summaries, typically due to coher- ence degradation, readability deterioration, and topical under-representation. Lexical repetition is instrumental to, among other things, the topical make-up of a text, and in our framework a lexical repetition-based model of dis- course segmentation, capable of detecting topic shifts, is integrated with a linguistically-aware summarizer utiliz- ing notion...
