چکیده مقاله:

Background. Although the World Taekwondo federation currently applies the APIS ranking method to calculate the Olympic rankings, some limitations exist. Objectives. This study applies the PageRank model to Olympics Taekwondo rankings. Methods. The 2015-2018 World Taekwondo Grand Prix competition results for women’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 women’s weight class, and KIM, SO-HUI, player of Korea(KOR), and WONGPATTANKAKIT, PANIPAK, player of Thailand (THA), were ranked second. At -57kg, Great Britain (GBR) ’s JONES, and JADE was ranked 1st, Turkey (TUR) ’s TARTAR, Nauru (NRU) (2nd and Latvia (LAT) ’s TARVIDA, INESE the 3rd. At -67kg, Lvory Coast (CIV) ’s GBAGBI, RUTH was ranked 1st, KOR’s OH, HYERI player, and TUR’s TATAR, NUR. In the +67kg, CHN’s ZHENG, SHUYIN ranked number 1, GBR’s WALKDEN, BIANKA ranked second, and Poland (POL) ’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 for measuring the ranking in Taekwondo competitions than the current APIS system, which we believe the page ranking method is suitable for measuring rankings in various sports events other than Taekwondo.

Generalization of the PageRank Model

This paper develops a generalization of the PageRank model of page centralities in the global webgraph of hyperlinks. The webgraph of adjacencies is generalized to a valued directed graph, and the scalar dampening coefficient for walks through the graph is relaxed to allow for heterogeneous values. A visitation count approach may be employed to apply the more general model, based on the number ...
