摘要
之前关于社会化单类协同排序推荐算法的研究仅仅集成用户的社交网络信息到推荐模型中,未能考虑到用户的社交信任网络的传递性。为了解决该问题,基于最新的CLiMF模型和TrustMF模型,提出了一种新的基于信任的社会化单类协同排序推荐算法(TrustOCCR)。该算法通过精心整合双重稀疏信息(隐式评分矩阵和具有传递性的社交信任网络矩阵)来进一步提高社会化单类协同排序推荐算法的性能。在真实的实验数据集上验证,采用两个不同的评价指标,本文提出的TrustOCCR算法均优于最新的社会化单类协同排序推荐算法。且TrustOCCR算法可扩展性好,适合在互联网信息推荐领域用于处理大数据。
Abstract
The problem with previous studies of social One Class Collaborative Ranking (OCCR) algorithms is that they
simply integrated the user's social network information into their model, without taking into account the transmission of
social trust networks between users. To solve this problem, a new social one class collaborative ranking recommendation
algorithm (TrustOCCR) based on CLiMF model and the newest TrustMF model is proposed, which aims to improve the
performance of social one class collaborative ranking recommendation by integrating twofold sparse data, i.e., implicit
feedback data and the transitive social trust network data. Experimental results on practical dataset show that our proposed
TrustOCCR algorithm outperformed existing state-of-the-art OCCF approach over di?erent evaluation metrics, and that
the TrustOCCR algorithm possesses good expansibility and is suitable for processing big data in the ?eld of internet
information recommendation.
