4 Conclusion and Future Work
</SectionTitle>
    <Paragraph position="0"> We have argued that the GRE task becomes very different when some commonly-made assumptions are abandoned: some distractors might be worse than others (section 3.1); the target may be impossible to distinguish precisely (section 3.2); the speaker may be unsure what the hearer knows (section 3.3); or there may be a need for over-specification (section 3.4)). As a result, it may be necessary to consider other aspects of the descriptions and their denotations, not simply counting distractors or numbers of properties. Some effects could perhaps be modelled using costs which are notsimplelinearfunctions, butwhichgivevarying importance to particular aspects of the denotation of a description, or of its content. We hope that this approach will ultimately shed light not only on the effect of the discourse situation, but also some aspects of generating indefinite descriptions.</Paragraph>
