Query: Multi-Paragraph Segmentation of Expository Text   This paper describes TextTiling, an algorithm for partitioning expository
texts into coherent multi-paragraph discourse units which reflect the subtopic
structure of the texts. The algorithm uses domain-independent lexical frequency
and distribution information to recognize the interactions of multiple
simultaneous themes. Two fully-implemented versions of the algorithm are
described and shown to produce segmentation that corresponds well to human
judgments of the major subtopic boundaries of thirteen lengthy texts.
