Soccer simulation commentary system is a suitable test bed for exploring
real time systems
simulation environment requires that the system generates real time comments based on the information received from the
. In this article, a three-layer architecture of Caspian Soccer Commentary system is presented, and each component of the system is briefly described. The emphasis of this paper is on design and implementation of the
subsystems. The Analyzer takes advantage of the
to keep track of the game situations. The
mechanism is proposed to improve the efficiency of the Content Selector subsystem. The presented Commentary System together with the other Caspian presentation and analysis tools won the first place in RoboCup 2003 Game Presentation and Match Analysis competitions.
