High-level online methods become more and more attractive with the increasing abilities of players and teams in the simulation league of the RoboCup domain. As in real soccer, the recognition and prediction of strategies (e.g. opponent's formation), tactics (e.g. wing play, offside traps), and situations (e.g. passing behavior) is important.

The talk is based on a new approach where spatio-temporal relations between objects are described and interpreted in order to detect some of the above mentioned situations. An extension to this approach enables us to both interpret and predict complex situations. It is based on a qualitative description of motion scenes and additional background knowledge. The method is applicable to a variety of situations. Our experiment consists of numerous offside situations in simulation league games.

A discussion reveals that this approach is valuable for future use because it is (a) possible to use the method in real-time, (b) we can predict situations giving us the option to refine agents actions in a game, and (c) it is domain independent in general.
