Abstract
In this paper I will discuss the properties of a tactical generation approach that has become popular recently: head-driven bottom-up generation. It is assumed that bidirectional grammars written in some unificationor logic-based formalism define relations between strings and some representation, usually called logical form. The task for a generator is to generate for a given logical form the strings that are related to this logical form by the grammar. In the paper it will be shown that the `early' approaches to this conceivement of the generation problem such as [21], [31] and [7] are not entirely satisfactory for general purposes. Furthermore I will define a simple bottom-up generator, called BUG1 for reference, as prototypical for the head-driven bottom-up approach as defended by for example [30, 5, 23, 24]. I will argue that head-driven bottom-up generation is to be preferred because the order of processing is directed by the input logical form and the information available in le...
