KB4Rec v1.0

KB4Rec v1.0是由中国人民大学信息学院创建的一个公开链接知识库与推荐系统的数据集。该数据集通过链接三个广泛使用的推荐系统数据集（MovieLens、LFM-1b和Amazon book）与流行的知识库Freebase，形成了大量的链接ID对。数据集的创建过程涉及从推荐系统数据集中提取信息，并通过离线Freebase搜索API进行实体链接。KB4Rec v1.0数据集主要应用于知识感知推荐系统的研究，旨在解决如何获取丰富和结构化的知识信息以增强推荐系统性能的问题。

KB4Rec v1.0 is a public dataset that integrates public knowledge bases and recommender systems, developed by the School of Information, Renmin University of China. It links three widely adopted recommender system datasets (MovieLens, LFM-1b, and Amazon book) with the popular knowledge base Freebase, resulting in a large number of linked ID pairs. The dataset's construction involves extracting information from existing recommender system datasets and conducting entity linking via the offline Freebase Search API. The KB4Rec v1.0 dataset is primarily utilized for research on knowledge-aware recommender systems, with the goal of addressing the challenge of acquiring rich and structured knowledge information to enhance the performance of recommender systems.
