5 Conclusions
</SectionTitle>
    <Paragraph position="0"> It has only been possible here to introduce the basic concerns of the PTT account of dialogue modelling and to pick out one or two illustrative examples to highlight the implementational approach which has  been assumed. Current and future work is directed towards measuring the theory against more challenging data to test its validity; cases where grounding is less automatic are an obvious source of such tests, and we have identified a few relevant problem cases in the Autoroute dialogues. We do claim, however, that the implementation as it stands validates a number of key aspects of the theory and provides a good basis for future work in dialogue modelling.</Paragraph>
