This study aims to verify the validity of a ranking model for Chinese table tennis players using the PageRank algorithm. A total of 629 matches in men's singles, doubles, and team events were selected as the research subjects. The rankings obtained using the PageRank algorithm showed that Ma Long ranked first in men's singles, Ma Long and Xu Xin ranked first in men's doubles, and Guangdong ranked first in the men's team category. Classification accuracy, sensitivity, specificity, and LoI were calculated to validate the ranking model, and the results demonstrated that the PageRank algorithm-based model outperformed the ranking model currently used by the China Table Tennis Association in terms of classification accuracy, sensitivity, specificity, and LoI. This study provides an objective and reliable ranking approach based on the performance of players and teams, which can be considered as an alternative to the existing point-based ranking system.
