Content Based Player and Game Interaction Model for Game Recommendation in the Cold Start setting
This addresses the challenge of recommending games to new users or for new titles in real-world applications, though it is incremental as it builds on existing content-based methods.
The paper tackles the cold start problem in game recommendation by developing content-based interaction models that generalize to new games and players, outperforming collaborative filtering in these tasks.
Game recommendation is an important application of recommender systems. Recommendations are made possible by data sets of historical player and game interactions, and sometimes the data sets include features that describe games or players. Collaborative filtering has been found to be the most accurate predictor of past interactions. However, it can only be applied to predict new interactions for those games and players where a significant number of past interactions are present. In other words, predictions for completely new games and players is not possible. In this paper, we use a survey data set of game likes to present content based interaction models that generalize into new games, new players, and both new games and players simultaneously. We find that the models outperform collaborative filtering in these tasks, which makes them useful for real world game recommendation. The content models also provide interpretations of why certain games are liked by certain players for game analytics purposes.
