Background. Although the APIS ranking method is currently applied by the World Taekwondo federation to calculate the Olympic rankings, there are some limitations. Objectives. This study applies the PageRank model to Olympics Taekwondo rankings. Methods. The results of the 2015-2018 World Taekwondo Grand Prix competition for womenchr('39')s four weight classes (-49kg, -57kg, -67kg, +67kg) were used as research data, totaling 624 games. Excel and NetMiner programs were used to calculate the PageRank value and the damping factor d was set to 0.15. Results. player of People’s Republic of China (CHN), WU and JINGYU, was ranked as No. 1 in the case of -46kg Olympic womenchr('39')s weight class and KIM, SO-HUI, player of Korea(KOR), and WONGPATTANKAKIT, PANIPAK, player of Thailand (THA), were ranked 2nd. At -57kg, Great Britain (GBR)chr('39')s JONES, JADE was ranked 1st, Turkey (TUR)chr('39')s TARTAR, Nauru (NRU) (2nd, and Latvia (LAT)chr('39')s TARVIDA, INESE the 3rd. At -67kg, Lvory Coast (CIV)chr('39')s GBAGBI, RUTH was ranked 1st, KORchr('39')s OH, HYERI player and TURchr('39')s TATAR, NUR. In the +67kg, CHNchr('39')s ZHENG, SHUYIN ranked number 1, GBRchr('39')s WALKDEN, BIANKA ranked second, and Poland (POL)chr('39')s KOWALCZUK, AKEKSANDRA ranked third. Second, as a result of comparing the validity of the PageRank model and the APIS model, the validity of the PageRank model was relatively higher in all four weight classes. Conclusion. The page ranking method was found to be more valid to measure the ranking in Taekwondo competitions than the current APIS system, which we believe the page ranking method is suitable to measure rankings in various sports events other than Taekwondo.
