This chapter discusses the task of topic segmentation: automatically dividing single long recordings or transcripts into shorter, topically coherent segments. First, we look at the task itself, the applications which require it, and some ways to evaluate accuracy. We then explain the most influential approaches -generative and discriminative, supervised and unsupervised -and discuss their application in particular domains.
