  Abstract:   Lexical chains represent a very powerful base for segmentation andmany papers are devoted to this problem. In our study we apply a new methodfor obtaining the boundaries, a method that relies on the number of chains whichend in a sentence, which begin in the following sentence and which traverse thesetwo successive sentences. The method is successfully experimented and evaluatedon ten texts from DUC02 conference both for a set of automated obtained lexicalchains and for two sets of human obtained lexical chains (pair to pair and againstto the manual segmentation).
