From the viewpoint of networks, a ranking system for players or teams in sports is equivalent to a centrality measure for sports networks, whereby a directed link represents the result of a single game. Previously proposed network-based ranking systems are derived from static networks, i.e., aggregation of the results of games over time. However, the score of a player (or team) fluctuates over time. Defeating a renowned player in the peak performance is intuitively more rewarding than defeating… 
A subgraph-based ranking system for professional tennis players
TLDR
A ranking system which relies on the occurrences of 4-node directed subgraphs and the positions (or orbits) where the players appear on them to extract meaningful rankings which capture the intricate competitive relationships between players from different eras.

Time-dependent Network Algorithm for Ranking in Sports
TLDR
A novel ranking method which may be useful in sports like tennis, table tennis or American football, etc. is introduced and analyzed and it has a good predictive power.
Ranking Competitors Using Degree-Neutralized Random Walks
TLDR
This work proposes a ranking method based on the random walk on the network representing the competitors as nodes and competitions as directed edges with asymmetric weights that outperforms other methods including the baseline win–loss differential method in sparse networks.
Hierarchical Ranking of Cricket Teams Incorporating Player Composition
TLDR
It is shown that player composition along with match characteristics is also an important aspect of team ranking, which has not been explored previously, and significant improvements in predicting match outcomes against other ranking schemes are reported.
Limits of PageRank-based ranking methods in sports data
TLDR
A new PageRank variant is proposed which outperforms PageRank in all evaluated settings, yet shares its sensitivity to increased randomness in the data, which demonstrates the danger of using novel metrics and algorithms without considering their limits of applicability.
Dynamic Ranking with the BTL Model: A Nearest Neighbor based Rank Centrality Method
TLDR
An extension of the classic BTL (Bradley-Terry-Luce) model for the static setting to a dynamic setup under the assumption that the probabilities of the pairwise outcomes evolve smoothly over the time domain [0, 1].
A new method for comparing rankings through complex networks: Model and analysis of competitiveness of major European soccer leagues
TLDR
A new technique to analyze families of rankings based on sports rankings and, more precisely, on soccer leagues is shown, which gives a generalization of the Kendall's correlation coefficient to more than two rankings.
The Evaluation of Rating Systems in Team-based Battle Royale Games
TLDR
Among all metrics studied, normalized discounted cumulative gain (NDCG) demonstrated more reliable performance and more flexibility, and alleviated most of the challenges faced by the other metrics while adding the freedom to adjust the focus of the evaluations on different groups of players.
The Haka network: Evaluating rugby team performance with dynamic graph analysis
TLDR
It is discovered that structural features that make networks resilient to disruptions are a good predictor of a team's performance, both at the global and at the local level, when deploying the dynamic graph analysis framework on data from 18 rugby matches.

An Iterative Procedure for Evaluating Digraph Competitions
TLDR
A competition which is based on the results of (partial) pairwise comparisons can be modelled by means of a directed graph and an iterative process is described that repeats this procedure: at each step the allocation obtained in the previous step determines the new input weights.

Using a model for minimizing violations that exploits problem characteristics found in college football, it was found that all previous ranking systems generated violations that were at least 38 percent higher than the minimum.
