AbstractLexical cohesion is an important device for signalling text organisation. In this
paper, we investigate to what extent idiomatic expressions participate in the cohesive structure
of a text. We look at the problem both from an empirical and a computational perspective.
Our results show that both literal and nonliteral expressions exhibit cohesion with their context,
though the latter tend to do so to a lesser extent. We also show that cohesive links identified
by humans can be approximated by an automatically computable semantic relatedness measure
based on search engine page counts. [Edit]
