5 Conclusions and future work
</SectionTitle>
    <Paragraph position="0"> In this paper we have presented an architecture for dialogue systems where a Domain Knowledge Manager and a Dialogue Manager cooperate to achieve natural interaction. Information providing dialogue systems based on this architecture can handle a variety of requests; simple and complex concerning the domain, and requests for system related information.</Paragraph>
    <Paragraph position="1"> Separating domain knowledge reasoning from dialogue and task knowledge reasoning has a number of advantages. First of all, it is clearer what the responsibilities and possibilities of the different modules are, e.g. the dialogue manager handles the dialogue and not domain reasoning. Furthermore, it facilitates customisation to new application domains. Another important feature is that domain knowledge sources can easily be replaced, added, removed, and reused. This implies that a system can be made more intelligent by adding new domain agents without changing the dialogue and task models.</Paragraph>
    <Paragraph position="2"> Future challenges are to apply the proposed architecture, utilising a Domain Knowledge Manager, to other domains and types of dialogue systems, such as advisory or tutoring systems. For such systems other knowledge sources like user models and argumentation models are relevant and have to be incorporated in the system architecture. null</Paragraph>
