This paper describes TextTiling, an algorithm for parti- tioning expository texts into coherent multi-paragraph discourse units which reflect the subtopic structure of the texts. The algorithm uses domain-independent lex- ical frequency and distribution information to recog- nize the interactions of multiple simultaneous themes. Two fully-implemented versions of the algorithm are de- scribed and shown to produce segmentation that corre- sponds well to human judgments of the major subtopic boundaries of thirteen lengthy texts.
