Abstract: Scheduling results for sport tournament in Olympics should satisfy the tournament routine, programming rules and demands of each sport. It should satisfy all constraints to the max. The tournament scheduling constraints in Olympics had characters of large numbers of quantity and category, dynamic alterability. The semantic representation method, established by constraint templates and constraint items based on the relation database, had flexible and extensible advantages. It realized the functions of representing, parsing, interacting and storing scheduling constraints, also resolved man-machine interactive and dynamic alterable problems.

Key words: semantic, constraint, constraint item, constraint template, constraint parsing
