This paper deals with the automatic translation of route descriptions into graphic sketches. We discuss some general problems implied by such inter-mode transcription. We propose a model for an automatic text-to-image translator with a two-stage intermediate representation in which the linguistic representation of a route description precedes the creation of its conceptual representation. | From route descriptions to sketches a model for a text-to-image translator Lidia Fraczak LIMSI-CNRS bât. 508 BP 133 91403 Orsay cedex France fraczak@ Abstract This paper deals with the automatic translation of route descriptions into graphic sketches. We discuss some general problems implied by such inter-mode transcription. We propose a model for an automatic text-to-image translator with a two-stage intermediate representation in which the linguistic representation of a route description precedes the creation of its conceptual representation. 1 Introduction Computer text-image transcription has lately become a subject of interest prompting research on relations between these two modes of representation and on possibilities of transition from one to the other. Different types of text and of images have been considered for example narrative text and motion pictures Kahn 1979 Abraham and De-sclés 1992 spatial descriptions and 3-dimensional sketches Yamada et al. 1992 Arnold and Lebrun 1992 2-dimensional spatial scenes and linguistic descriptions André et al. 1987 2-dimensional image sequences and linguistic reports André et al. 1988 . Linguistic and pictorial modes may be considered as complementary since they are capable of conveying different kinds of content Arnold 1990 . This complementarity of expression is explored in order to be used in multi-modal systems for human-computer interaction such as computer assisted architectural conception Arnold and Lebrun 1992 . Such systems should not only use different modes to ensure better communication but should also be able to pass from one to the other. Given the differences in capacities of these two means of expression one may expect some problems in trying to encode into a picture the information contained in a linguistic description. The present research is concerned with route descriptions RDs and their translation into 2dimensional graphic sketches. We deal with a type of discourse whose informational .
