In this paper the experience made through the development of a NAtural Language driven Image Generation is discussed. This system is able to imagine a static scene described by means of a sequence of simple phrases. In particular, a theory for equilibrium and support will be outlined together with the problem of object positioning. | NAtural Language driven Image Generation Giovanni Adorni Mauro Di Manzo and Fausto Giunchiglia Department of Communication Computer and System Sciences University of Genoa Via Opera Pia II A - 16145 Genoa - Italy ABSTRACT In this paper the experience made through the development of a NAtural Language driven Image Generation is discussed.

Introduction A challenging application of the Al techniques is the generation of 2D projections of 3D scenes starting from a possibly unformalized input as a natural language description. Apart from the practically unlimited simulation capabilities that a tool of this kind could give people working in the show business a better modeling of the involved cognitive processes is important not only from the point of view of story understanding Wa80a Wa81a but also for a more effective approach to a number of Al related problems as for instance vision or robot planning So76a . In this paper we discuss some of the ideas on which is based a NAtural Language driven Image Generation NALIG from here on which has been developed for experimental purposes at the University of Genoa. This system is currently able to reason about static scenes described by means of a set of simple phrases of the form subject prepositions object reference . The understanding process in NALIG flows through several steps distinguishable only from a logic point of view which perform object instantiation relation inheritance translation of the surface expression into unambiguous primitives NALIG has been developed for the Italian language the prepositions it can presently analyze are su sopra sotto a destra a sinistra vici-no davanti dietro in. A second deeply revised release is currently under design. This work has been supported by the Italian .
