    <Paragraph position="0"> Whereas a lot of work has been done in the area of spatial databases (Shekhar et al., 1999; Freytag et al., 2000; Paredaens, 1995; Paredaens and Kuijpers, 1998), little attention seems to have been given so far to the problem of generating maps from text or annotating maps with information elicited from unstructured documents.</Paragraph>
    <Paragraph position="1"> The work presented here perhaps most closely resembles that of (Mackinlay, 1986; Casner, 1990; Roth and He ey, 1993) who describe systems that generate multimedial representations, potentially including maps, but from a formalized knowledge source rather than unstructured text, and (Waldinger et al., 2002), who describe Geo-Logica, a system that can transform requests to see a place (formulated in natural language) into a three-dimensional aerial view.</Paragraph>
