    <Paragraph position="0"> As information services and domains grow more complex the complexity of dialogue systems increases. They tend to need more and more domain knowledge and the domain reasoning mechanisms also have to become more sophisticated. Utilising domain knowledge reasoning is in many cases necessary for a dialogue system to interpret and respond to a request in an intelligent manner, especially as requests can be vague and sometimes ambiguous. This involves not only requests for information from application specific knowledge sources, but also requests related to the properties and structures of the application and requests that are outside the scope of the application. Thus, dialogue systems must be able to access, gather and integrate knowledge from various domain knowledge sources and application systems in order to determine the precise meaning of a request and produce an appropriate response. However, although the dialogue system gather information from various sources it differs from the information retrieval problem discussed for instance in Stein et al. (1999). We assume that the tasks are well-defined and that the users have articulated information needs that they can express in specific terms.</Paragraph>
    <Paragraph position="1"> In this paper we will discuss how these different tasks can be performed in dialogue systems of simple service character, i.e. dialogue systems that can provide information given a set of parameters collected from the user (Hayes and Reddy, 1983).</Paragraph>
