Abstract : In the general context of a man-machine dialogue system, the adequate representation of the different kinds of data given by the user is very important. We present in this paper a method for representing temporal and spatial pieces of knowledge in an integrated manner, based on previous works done on temporal zones. Firstly, we present the two levels of time and space seperately, though they work on the same principles. Then, we show how these notions interact with each other through the definition of an object-universe, a structure which bears the different states and events undergone by any object referred to in a NL discourse. Within this representation, we propose a mechanism to acquire knew pieces of information by comparing two complex space-time structures. This leads us to show that the two levels are complementary to compute a specific situation in the world. Finally, we briefly address the use that can be made of this model to the understanding of a series of utterance in the present tense (description of a situation) and to the representation of the notion of event.
