2 Architecture of the system
</SectionTitle>
    <Paragraph position="0"> The architecture of the system is shown in Figure 1. The initial data for the system are the dataset and a specification of the final product prepared by the user in the form of a template. The system works as follows:  1. The monitor interprets the template and successively calls the scanner, the planner, the text or map generator, and the formatter with parameters extracted from the template.</Paragraph>
    <Paragraph position="1"> 2. The scanner analyzes the dataset and extracts assertions about the weather situation.</Paragraph>
    <Paragraph position="2"> 3. The planner applies rhetorical and grammatical knowledge to convert the extracted set of assertions into a surface structure or a map plan.</Paragraph>
    <Paragraph position="3"> 4. The text generator makes use of the lexicon to linearize the surface structure into a text; the map generator creates a cartographical presentation from the map plan using the visual library.</Paragraph>
    <Paragraph position="4"> 5. The monitor evaluates the generated text against  parameters specified in the template (e.g. length of the text), and if the result does not meet the requirements of the user, re-activates the previous processors with adjusted parameters for providing alternative solutions.</Paragraph>
