Huiyu Li, Pei Liang, Junhua Hu

AI总结:

本文提出PIM+RA方法,通过带自连接边和权重的二分网络及改进皮尔逊相关系数优化资源分配,在提升推荐准确性的同时改善覆盖率、多样性和新颖性,并增强长尾物品曝光。

摘要:

推荐系统已被公认为管理信息过载的有效工具。然而,此类系统中采用的传统算法主要强调精确推荐,因此忽略了其他重要方面,如物品的覆盖率、多样性和新颖性。这种方法导致长尾物品的曝光较少。在本文中,为了个性化推荐并更有针对性地分配推荐资源,提出了一种名为PIM+RA的方法。该方法利用一个包含自连接边和权重的二分网络。此外,采用改进的皮尔逊相关系数以实现更好的再分配。对PIM+RA的评估表明,不仅在准确性方面,而且在推荐的覆盖率、多样性和新颖性方面都有显著提升。它通过为长尾物品提供有效曝光,使推荐频率达到更好的平衡,同时允许自定义参数来调整推荐列表的偏差。

英文摘要:

Recommender systems have been acknowledged as efficacious tools for managing information overload. Nevertheless, conventional algorithms adopted in such systems primarily emphasize precise recommendations and, consequently, overlook other vital aspects like the coverage, diversity, and novelty of items. This approach results in less exposure for long-tail items. In this paper, to personalize the recommendations and allocate recommendation resources more purposively, a method named PIM+RA is proposed. This method utilizes a bipartite network that incorporates self-connecting edges and weights. Furthermore, an improved Pearson correlation coefficient is employed for better redistribution. The evaluation of PIM+RA demonstrates a significant enhancement not only in accuracy but also in coverage, diversity, and novelty of the recommendation. It leads to a better balance in recommendation frequency by providing effective exposure to long-tail items, while allowing customized parameters to adjust the recommendation list bias.
