This article outlines a new method of locating discourse boundaries based on
lexical cohesion and a graphical technique called dotplotting. The application
of dotplotting to discourse segmentation can be performed either manually, by
examining a graph, or automatically, using an optimization algorithm. The
results of two experiments involving automatically locating boundaries between
a series of concatenated documents are presented. Areas of application and
future directions for this work are also outlined.
