OARNetP: Object-Attribute-Relation Network for Predicting Soccer Events

Event prediction involves analyzing and forecasting events that occur at a specific time and location to inform decision-making and take the next actions. Current event prediction approaches primarily employ deep learning methods to analyze regular patterns from large amounts of historical data. However, predicting adversarial soccer events remains a significant challenge due to strong antagonism and complex relationships between players. With this consideration, we propose an objectattribute-relation (OAR) network for predicting soccer events using multimodal data, including spatiotemporal trajectory data and video data. The proposed scheme aims to enhance prediction performance by transforming multimodal data into an OAR space that integrates global and local relationships (adversarial information and multi-objective information). In particular, the scheme consists mainly of a relation module, an object attribute module, and a graph prediction module. We first use ConvLSTM to extract the visual features of players from video data and use LSTM to extract the movement features of players from spatiotemporal data. Additionally, we apply a multihead GRU attention mechanism to calculate the relation weights. These three components are then combined into an OAR graph of a clip in a soccer game. Finally, an OAR GNN is designed to determine the influence of different objects and predict events. The entire process constitutes an end-to-end event prediction learning framework. Extensive experimental results on the two challenging datasets, namely, soccER and SkillCorner, verify the effectiveness of the proposed framework.
