论文摘要

最近的发展和对神经符号模型的兴趣越来越大,这表明混合方法可以为人工智能提供更丰富的模型。有效的关系学习和推理方法的整合是这个方向上的关键挑战之一,因为神经学习和象征性推理提供了可以使AI系统开发的互补特征。关于知识图的关系标签或链接预测已成为基于深度学习的自然语言处理研究的主要问题之一。此外,使用神经符号技术的其他领域也可能受益于此类研究。在知识图中,已经做出了几项努力,以识别现有事实。两条研究线尝试通过考虑将它们连接的所有已知事实或将它们连接的事实的几个途径进行考虑,并尝试预测两个实体之间的知识关系。我们提出了一个神经符号图神经网络,该神经网络通过将模型的嵌入包含包含此类路径的知识图的最小值子集嵌入,从而在所有路径上应用学习。通过学习为与单词嵌入相对应的实体和事实产生表示形式,我们展示了如何端对端训练模型以解码这些表示形式并在多任务方法中推断实体之间的关系。我们的贡献是两个方面:一种神经符号方法,利用了大图中的关系推断的分辨率,我们还证明,这种神经符号模型比基于路径的方法更有效

The recent developments and growing interest in neural-symbolic models has shown that hybrid approaches can offer richer models for Artificial Intelligence. The integration of effective relational learning and reasoning methods is one of the key challenges in this direction, as neural learning and symbolic reasoning offer complementary characteristics that can benefit the development of AI systems. Relational labelling or link prediction on knowledge graphs has become one of the main problems in deep learning-based natural language processing research. Moreover, other fields which make use of neural-symbolic techniques may also benefit from such research endeavours. There have been several efforts towards the identification of missing facts from existing ones in knowledge graphs. Two lines of research try and predict knowledge relations between two entities by considering all known facts connecting them or several paths of facts connecting them. We propose a neural-symbolic graph neural network which applies learning over all the paths by feeding the model with the embedding of the minimal subset of the knowledge graph containing such paths. By learning to produce representations for entities and facts corresponding to word embeddings, we show how the model can be trained end-to-end to decode these representations and infer relations between entities in a multitask approach. Our contribution is two-fold: a neural-symbolic methodology leverages the resolution of relational inference in large graphs, and we also demonstrate that such neural-symbolic model is shown more effective than path-based approaches
