	abstract = {Assuming that a linear paired comparison model is valid for a sport (which involves pairwise competitions), an axiomatic approach is used to obtain a system for updating ratings or strengths of players in the sport. Paired competitions with or without ties are both dealt with. Existing rating systems in chess and table tennis fit within the systems derived here.},
