【 摘 要 】

In this paper lexical cohesion modeling is considered. We argue that to model lexical cohesion in connected texts it is not enough to find related words in a text. It is important to take into account relations between entities participating in the described situations. Consideration ofthis factor gives the possibility to develop more flexible lexical chaining algorithms and to construct lexical chains more corresponding to the discourse structure. The multigraph representation seems to be appropriate as a basis for lexical cohesion modeling.
