具有社会正则化特征的推荐系统

Recommender Systems with Characterized Social Regularization

Tzu-Heng Lin, Chen Gao, Yong Li

摘要:

随着在线社交网络的迅速发展,利用社会关系来增强推荐系统的社会推荐近年来受到越来越多的关注。现有的社交推荐方法都是基于用户的偏好或决策会受到其社交好友行为的影响这一事实。然而,他们假设社会关系的影响总是相同的,这违背了用户可能与不同的朋友分享对不同产品的偏好的事实。本文通过设计一个通用的正则化项来建模变量社会影响力,提出了一个新的CSR(Characterized Social Regularization)模型。我们提出的模型可以应用于显式和隐式迭代。在真实数据集上的大量实验表明,CSR显著优于最先进的社交推荐方法。

英文摘要:

Social recommendation, which utilizes social relations to enhance recommender systems, has been gaining increasing attention recently with the rapid development of online social network. Existing social recommendation methods are based on the fact that users preference or decision is influenced by their social friends' behaviors. However, they assume that the influences of social relation are always the same, which violates the fact that users are likely to share preference on diverse products with different friends. In this paper, we present a novel CSR (short for Characterized Social Regularization) model by designing a universal regularization term for modeling variable social influence. Our proposed model can be applied to both explicit and implicit iteration. Extensive experiments on a real-world dataset demonstrate that CSR significantly outperforms state-of-the-art social recommendation methods.
