Abstract

This paper proposes a new indicator of text structure, called the lexical cohesion profile (LCP), which locates segment boundaries in a text. A text segment is a coherent scene; the words in a segment are linked together via lexical cohesion relations. LCP records mutual similarity of words in a sequence of text. The similarity of words, which represents their cohesivehess, is computed using a semantic ]letwork. Comparison with the text segments marked by a number of subjects shows that LCP closely correlates with the bu- ]nan judgments. LCP may provide valuable information for resolving anaphora and ellipsis.
