摘要:

大量的信息存在于用户撰写的评论中。这种信息源被大多数当前的推荐系统所忽略,但它可以潜在地缓解稀疏性问题并提高推荐质量。在本文中,我们提出了一个深度模型,从评论文本中联合学习项目属性和用户行为。提出的模型,命名为深度合作神经网络(DeepCoNN),由两个并行的神经网络耦合在最后一层。其中一个网络专注于利用用户撰写的评论来学习用户行为,另一个网络则从为项目撰写的评论中学习项目属性。在顶部引入共享层以将这两个网络耦合在一起。共享层使得为用户和项目学习的潜在因子能够以类似于因子分解机器技术的方式彼此交互。实验结果表明,DeepCoNN在各种数据集上的性能明显优于所有基线推荐系统。

英文摘要:

A large amount of information exists in reviews written by users. This source of information has been ignored by most of the current recommender systems while it can potentially alleviate the sparsity problem and improve the quality of recommendations. In this paper, we present a deep model to learn item properties and user behaviors jointly from review text. The proposed model, named Deep Cooperative Neural Networks (DeepCoNN), consists of two parallel neural networks coupled in the last layers. One of the networks focuses on learning user behaviors exploiting reviews written by the user, and the other one learns item properties from the reviews written for the item. A shared layer is introduced on the top to couple these two networks together. The shared layer enables latent factors learned for users and items to interact with each other in a manner similar to factorization machine techniques. Experimental results demonstrate that DeepCoNN significantly outperforms all baseline recommender systems on a variety of datasets.
