摘要 随着信息资源的动态性、复杂性和信息量的不断增加,推荐技术成为解决信息过载问题的最有效的技术之一。传统的推荐算法,如基于用户或物品的协同过滤,利用评分信息衡量用户或物品之间的相似程度。然而单一评分不能准确衡量用户偏好或物品之间的相似度,从而准确推荐。近年来,深度学习技术的应用在推荐系统中获得了显著的发展势头,用以更好地理解用户偏好、物品特征和历史交互等。在本文工作中,我们在降噪自编码器中融合影评信息作为辅助信息,即SemRe-DCF,本方法旨在学习物品描述的语义表示,及利用向量算法捕获细粒度的语义规则,从而获得更好的评分预测。结果表明,该方法能有效地提高预测精度和冷启动问题。

Abstract: With the ever-growing dynamicity, complexity, and volume of information resources, the recommendation technique is proposed and becomes one of the most effective techniques for solving the so-called problem of information overload. Traditional recommendation algorithms, such as collaborative filtering based on the user or item, only measure the degree of similarity between users or items with single criterion, i.e., ratings. According to the experience of previous studies, single criterion cannot accurately measure the similarity between user preferences or items. In recent years, the application of deep learning techniques has gained significant momentum in recommender systems for better understanding of user preferences, item characteristics, and historical interactions. In this work, we integrate plot information as auxiliary information into the denoising autoencoder (DAE), called SemRe-DCF, which aims at learning semantic representations of item descriptions and succeeds in capturing fine-grained semantic regularities by using vector arithmetic to get better rating prediction. The results manifest that the proposed method can effectively improve the accuracy of prediction and solve the cold start problem.
