摘要:

神经网络嵌入的成功引发了人们对使用知识图谱进行各种机器学习和信息检索任务的新兴趣。特别是,最近的推荐方法的基础上图嵌入显示出最先进的性能。通常,这些方法编码潜在的评级模式和内容特征。从以前的工作,在本文中,我们建议利用嵌入提取的图形,结合信息的评级和基于方面的意见,在文本评论。然后,我们适应和评估国家的最先进的图形嵌入技术,从亚马逊和Yelp评论六个域生成的图形,优于基线嵌入器。此外,我们的方法的优点是提供的解释,涉及的覆盖面的方面为基础的意见,由用户推荐的项目。

英文摘要:

The success of neural network embeddings has entailed a renewed interest in using knowledge graphs for a wide variety of machine learning and information retrieval tasks. In particular, recent recommendation methods based on graph embeddings have shown state-of-the-art performance. In general, these methods encode latent rating patterns and content features. Differently from previous work, in this paper, we propose to exploit embeddings extracted from graphs that combine information from ratings and aspect-based opinions expressed in textual reviews. We then adapt and evaluate state-of-the-art graph embedding techniques over graphs generated from Amazon and Yelp reviews on six domains, outperforming baseline recommenders. Additionally, our method has the advantage of providing explanations that involve the coverage of aspect-based opinions given by users about recommended items.
