5. Conclusion
</SectionTitle>
    <Paragraph position="0"> Several modules are involved in generation of natural language turns in a natural language dialog system. First, the Planner chooses among the currently activated goals of the dialog system those which the system would carry out in its reply to the user.</Paragraph>
    <Paragraph position="1"> Secondly, Turns'Generator constructs the semantic representation of the answer turn, i.e~ chooses the necessary communicative steps for carrying out the goals laid down by the Planner. It also fills in these steps with concrete data by using knowledge about the problrm domain and/or about the communicative process. The Linguistic Processor gi~ yes the finishing touches to the surface text.</Paragraph>
    <Paragraph position="2"> But before a turn is communicated to the user there should be a ~'check-up&amp;quot; unterpretatlon of it - the dialog system carries out the possible interpretations of th~s turn in its &amp;quot;mind&amp;quot; t using additional knowledge from its model of the partner and its knowledge base. The result is compared with the intended meaning of the turn and in case of discrepansies the system should ~eturn to the module where the interpretations were still similar in order to try another possible way of genera*long the answer turn~ Of the modules listed above there is a complete version of the Linguistic Processor both for parsing and generation running on a Ryad 1060 computer in the language PL/I~ The Turns'Generate~p~is being tested at the present time.</Paragraph>
