Abstract

This paper shows how lexical choice during text generation depends on linguistic context. We argue that making correct lexical choice in the textual context requires distinguishing properties of concepts, which are more or less independent of the language, from language-specific representations of text where lexemes and their semantic and syntactic relations are represented. In particular, Lexical Functions are well-suited to formalizing anaphoric lexical links in text, including the introduction of superordinates. This sheds new light on the notion of "basic level", which has recently been applied to lexical selection in generation. Some constraints governing the generation of lexical and grammatical anaphora are proposed for procedural text, using examples from the sublanguage of recipes.
