Although intensive work has been devoted to spatio-temporal qualitative reasoning models, some issues such as management of complex objects life and motion remain. In this paper, we propose a model dealing with existence and presence of object concepts. First, we introduce spatio-temporal states, which express existing spatio-temporal relationships between two objects at a given time. Spatio-temporal states decision tree is presented. Based on this new representation, we construct a finite set of life and motion configurations which can be seen as a way to categorise spatio-temporal histories. Then, we present the model itself which is based on 25 generalized life and motion configurations. Indeed, these generalized configurations are assimilated to line-line topological relationships obtained by projecting life and motion configurations in a primitive space. Finally, generalized life and motions configurations conceptual neighbourhood diagram and their interpretation in natural language are given.Read the full paper here: https://link.springer.com/chapter/10.1007/978-3-540-87991-6_39
