基于知识感知交互匹配的个性化新闻推荐

Personalized News Recommendation with Knowledge-aware Interactive Matching

Tao Qi, Fangzhao Wu, Chuhan Wu, Yongfeng Huang

摘要:

个性化新闻推荐最重要的任务是候选新闻与用户兴趣的准确匹配。现有的大多数新闻推荐方法都是从文本内容和用户点击的兴趣两方面独立地对候选新闻进行建模。然而,一篇新闻文章可能涵盖多个方面和实体,并且用户通常具有不同种类的兴趣。候选新闻和用户兴趣的独立建模可能导致新闻和用户之间的较差匹配。本文提出了一种基于知识感知的交互式新闻推荐匹配方法。我们的方法交互式模型候选新闻和用户的兴趣,以促进他们的准确匹配。我们设计了一个知识感知的新闻协同编码器,以交互式地学习表示的点击新闻和候选新闻捕捉它们的相关性在语义和实体的帮助下,知识图谱。我们还设计了一个用户-新闻联合编码器来学习候选新闻感知的用户兴趣表示和用户感知的候选新闻表示,以便更好地进行兴趣匹配。在两个真实数据集上的实验验证了该方法能够有效地提高新闻推荐的性能。

英文摘要:

The most important task in personalized news recommendation is accurate matching between candidate news and user interest. Most of existing news recommendation methods model candidate news from its textual content and user interest from their clicked news in an independent way. However, a news article may cover multiple aspects and entities, and a user usually has different kinds of interest. Independent modeling of candidate news and user interest may lead to inferior matching between news and users. In this paper, we propose a knowledge-aware interactive matching method for news recommendation. Our method interactively models candidate news and user interest to facilitate their accurate matching. We design a knowledge-aware news co-encoder to interactively learn representations for both clicked news and candidate news by capturing their relatedness in both semantic and entities with the help of knowledge graphs. We also design a user-news co-encoder to learn candidate news-aware user interest representation and user-aware candidate news representation for better interest matching. Experiments on two real-world datasets validate that our method can effectively improve the performance of news recommendation.
