5. Conclusion
</SectionTitle>
    <Paragraph position="0"> I have argued that an intermediate level of representation is needed within the text planner in which to compose the utterance and that this representation should be in abstract linguistic terms. Making the vocabulary in which the text planner makes its decisions be an abstraction over the concrete resources of the language simplifies the decision making in the composition process, since the text planner need not deal with the particular grammatical details of the language.</Paragraph>
    <Paragraph position="1"> Furthermore, since the abstract vocabulary captures all and only those combinations of resources that occur in the language and since its terms constrain the composition with other terms, the representation serves to ensure that the decisions that the text planner makes when composing the utterance will not have to be retracted, that is, that the utterance the text planner composes will be expressible in language.</Paragraph>
    <Paragraph position="2"> I have shown how a preliminary planning vocabulary can be developed by approaching the problem from two sides: (1) using research in linguistics and text analysis to determine a set of abstractions over concrete linguistic resources and (2) using these terms in a text planner generating text from a real application to empirically test the usefulness of this set for generating. The long rang challenge of this work will be continuing this bidirectional development and testing process to define an intermediate representation that both covers the expressiveness of natural language and ensures the expressibility of the generator's text plan.</Paragraph>
