The Interpretation and Representation of Coreferential, Lexical NP's in Expository Texts

The central topic of this article is the relationship between coreferential, non-identical, lexical NPs in texts (so-called NPi-NPi'-pairs). The main question in this article is which interpretation and representation must be attributed to the relationship between NPi and NPi' if they are to justify the (referential, cohesive and informative) functions and the adequacy of NPi' in texts.
The answer has been given in terms of text relations and text intentions. It has been argued that the adequacy of NPi-NPi'-pairs cannot simply be made dependent upon either the status of the entities involved in the reader's knowledge store, or the surface characteristics of sentences or texts, such as the distance or the structural relation between NPi and NPi'. Rather,the adequacy is dependent on the question whether NPi-NPi'-pairs are adequate actualizations of implicit text relations which, in turn, have to be adequate specifications of the intentionsunderlying the text. Such a treatment enables us to construct a representation for NPi-NPi'- pairs in which the different functions of NPi's are incorporated.
