Recently the problem of choosing communicatively adequate lexemes has attracted much interest in the NL generation community, in general, the task amounts to deciding for a given representation of an intended meaning, which words will most appropriately convey that meaning to the addressee. Whether lexical choice must be exact in the sense that all and only the intended meaning is verbalized, depends on the respective communication situation. In a multimodal discourse, where language is supplemented by gestures or graphics, the linguistic device need not convey everything to the partner. In written discourse without a predefined context, as in DISCO, exact verbalization seems much more in order. In all theories of lexical choice, the convergence problem has to be solved: there is always a decision for exactly one lexical item. We may distinguish the following subtasks of lexical choice: In this paper, we assume that for lexical selection the following kinds of knowledge are necessary: We will show that lexical choice requires a domain model based on linguistic considerations, and that standard KL-ONE techniques are insufficient for parts of the task at hand.
