摘要:

社交媒体的广泛使用凸显了其对社会和个人的潜在负面影响,这在很大程度上由塑造用户行为和社会动态的推荐算法驱动。理解这些算法至关重要,但由于社交媒体网络复杂、分布式的特性,以及真实世界数据获取有限,这一任务颇具挑战性。本研究提出使用学术社交网络作为代理,研究社交媒体中的推荐系统。通过采用图神经网络(GNNs),我们开发了一个将学术信息圈预测与行为预测分离的模型,使我们能够模拟推荐生成的信息圈,并评估模型在预测未来合作关系方面的性能。我们的方法旨在增进对推荐系统作用及社交网络建模的理解。为支持研究的可复现性,我们公开了实现代码:https://github.com/DimNeuroLab/academic_network_project

英文摘要:

The widespread use of social media has highlighted potential negative impacts on society and individuals, largely driven by recommendation algorithms that shape user behavior and social dynamics. Understanding these algorithms is essential but challenging due to the complex, distributed nature of social media networks as well as limited access to real-world data. This study proposes to use academic social networks as a proxy for investigating recommendation systems in social media. By employing Graph Neural Networks (GNNs), we develop a model that separates the prediction of academic infosphere from behavior prediction, allowing us to simulate recommender-generated infospheres and assess the model's performance in predicting future co-authorships. Our approach aims to improve our understanding of recommendation systems' roles and social networks modeling. To support the reproducibility of our work we publicly make available our implementations: https://github.com/DimNeuroLab/academic_network_project
