A dialogue system within a geographical information system has to understand and to generate texts in natural language. In particular, it applies spatial reasoning in order to identify or to localize the landmarks of the geographical environment. Therefore, the domain knowledge manager (i.e. the module that gather information), have to access to the contents of the geographical database, which represent the information usable by the GIS. Owing to the lack of a standard format, this manager has to deal with various contents and various organizations. In order to overcome this difficulty and to differentiate precisely the cases for which the dialogue system has to interrogate the user, we use, within this module, a pivot system. In this paper, we present this system and the possibilities that it offers for the dialogue system.
