论文摘要

知识图(KG)推理在学术界和行业中都变得越来越流行。基于符号逻辑的常规KG推理是确定性的,推理结果是可以解释的,而现代嵌入的推理可以处理不确定性并预测合理的知识,通常通过向量计算具有很高的效率。一个有希望的方向是将基于逻辑的方法和基于嵌入的方法集成在一起,并具有具有两者优势的愿景。近年来,它引起了广泛的研究关注。在本文中,我们全面调查了这些作品,重点介绍了逻辑和嵌入方式的集成方式。我们首先简要介绍了初步,然后从不同的角度系统地对逻辑和嵌入感知的KG推理进行分类和讨论,最后结论并讨论挑战和进一步的方向。

Knowledge graph (KG) reasoning is becoming increasingly popular in both academia and industry. Conventional KG reasoning based on symbolic logic is deterministic, with reasoning results being explainable, while modern embedding-based reasoning can deal with uncertainty and predict plausible knowledge, often with high efficiency via vector computation. A promising direction is to integrate both logic-based and embedding-based methods, with the vision to have advantages of both. It has attracted wide research attention with more and more works published in recent years. In this paper, we comprehensively survey these works, focusing on how logics and embeddings are integrated. We first briefly introduce preliminaries, then systematically categorize and discuss works of logic and embedding-aware KG reasoning from different perspectives, and finally conclude and discuss the challenges and further directions.
