摘要:

个性化推荐在互联网驱动的活动中很受欢迎,特别是购物。推荐方法可以分为三大类,基于内容的过滤,协同过滤和机器学习增强。关于不同用户的产品和偏好的信息主要用于推断特定用户的偏好。不充分的信息显然会导致这些方法失败或性能不佳。我们为这些方法提供的信息越多,这些方法就越有可能表现得更好。知识图谱代表了以实体之间的关系形式记录信息的当前趋势,并可以提供有关产品和用户的附加(侧面)信息。这些信息可以用于改进最近邻搜索,聚类用户和产品,或者在使用神经网络时训练神经网络。在这项工作中,我们提出了一个新的通用推荐系统框架,集成知识图谱到推荐管道。我们描述了它的软件设计和实现,然后通过实验表明,这样的框架可以专门为一个域,说电影推荐,并可能由于侧信息从知识图谱表示这样的信息得到的建议结果的改进。我们的框架支持不同的知识图谱表示格式,并方便格式转换,合并和信息抽取所需的训练推荐方法。

英文摘要:

Personalized recommendations are popular in these days of Internet driven activities, specifically shopping. Recommendation methods can be grouped into three major categories, content based filtering, collaborative filtering and machine learning enhanced. Information about products and preferences of different users are primarily used to infer preferences for a specific user. Inadequate information can obviously cause these methods to fail or perform poorly. The more information we provide to these methods, the more likely it is that the methods perform better. Knowledge graphs represent the current trend in recording information in the form of relations between entities, and can provide additional (side) information about products and users. Such information can be used to improve nearest neighbour search, clustering users and products, or train the neural network, when one is used. In this work, we present a new generic recommendation systems framework, that integrates knowledge graphs into the recommendation pipeline. We describe its software design and implementation, and then show through experiments, how such a framework can be specialized for a domain, say movie recommendations, and the improvements in recommendation results possible due to side information obtained from knowledge graphs representation of such information. Our framework supports different knowledge graph representation formats, and facilitates format conversion, merging and information extraction needed for training recommendation methods.
