Tennis Player Momentum Evaluation Model Based on Big Data and Game Theory-TOPSIS Method
This cutting-edge research introduces a comprehensive AI model for evaluating tennis player momentum, integrating big data analysis, game theory, and multi-attribute decision-making. By meticulously analyzing real-time match data from professional tournaments, the model constructs an evaluation system spanning offensive, defensive, and on-the-spot abilities with ten core technical and behavioral indicators. A novel weight fusion mechanism, combining subjective and objective methods, enhances scientific balance, while the TOPSIS method quantifies momentum fluctuations. This provides unprecedented scientific insights into player performance dynamics, offering powerful tools for strategic analysis, tactical formulation, and predictive modeling across competitive sports, with potential applications far beyond tennis.

Methodology Overview
Key Findings
Strategic Implications
The core innovation lies in a multi-faceted approach. First, match data from the 2023 Wimbledon Championships is leveraged to create a comprehensive indicator system across offensive, defensive, and on-the-spot abilities. This data includes winning points, net winning rate, unforced error rate, and ball speed. Second, a sophisticated weight fusion mechanism, integrating Analytic Hierarchy Process (AHP), Entropy Weighting Method, and Game Theory, ensures a balanced and scientific contribution of each indicator. Finally, the TOPSIS multi-attribute decision-making model calculates and ranks player momentum at various stages of the game, enabling dynamic analysis.

Visualization & Tactical Analysis
The model reveals critical insights into player performance. Analysis of the weighting results (Table 1) highlights the profound impact of indicators like first serve winning percentage, break point conversion rate, and first serve return rate on overall momentum, confirming their crucial role in match outcomes. Visualizations (Figures 2 and 3) effectively track momentum fluctuations game-by-game and set-by-set, accurately identifying key turning points and shifts in player dominance during a match. For example, a shift in return strategy by player 2 significantly impacted player 1's serving rhythm, leading to a decline in momentum.
First Serve Win %
Most Influential Indicator (Table 1)
| Approach | Traditional Methods | Game Theory-TOPSIS Model |
|---|---|---|
| Evaluation Scope | Single indicators, often subjective | Multi-dimensional, data-driven (Offensive, Defensive, On-the-spot) |
| Weighting Mechanism | Heuristic, expert-dependent, lacks scientific balance | Objective & Subjective Fusion (AHP, Entropy, Game Theory) |
| Output | Static, descriptive, weak dynamics | Dynamic momentum scores & ranking, real-time response |
| Insights | Limited causality, often ignores player interaction | Identifies trends, turning points, tactical shifts, psychological resilience |
This model offers significant practical value for various stakeholders. For coaches and athletes, it provides a quantitative tool for real-time tactical adjustments and personalized training interventions, enabling more precise performance optimization. For event analysts, it enhances match prediction and post-game analysis by revealing the underlying dynamics of momentum shifts. The methodology's robust integration of big data and game theory also makes it highly adaptable, with strong potential for application in other competitive sports like table tennis, badminton, and esports, driving data-driven decision-making across the broader sports industry.
Empowering Coaches with Real-time Insights
Imagine a scenario where a tennis coach can, during a match, precisely pinpoint when their player's momentum is shifting and why. This model provides that capability. By analyzing the ten key indicators through the Game Theory-TOPSIS framework, coaches can receive live feedback on crucial factors like first serve return rates or unforced error fluctuations. This allows for immediate, evidence-based tactical adjustments – perhaps advising a more aggressive return, a shift in serve placement, or a focus on maintaining composure during critical points. This capability moves beyond gut feeling, providing a scientific edge in high-stakes environments, transforming real-time coaching decisions.
