这些学习到的低维向量能被KGC和推荐系统等使用。在本文中,我们使用其来解决QA-KG问题。然后,仍然有一个问题就是一个谓词在自然语言中能有不同的表示。此外,模棱两可的实体名字和有些实体仅有部分名称使得可能回答会有很多。 为了打破此限制,我们提出了KEQA框架。我们关注于回答最通用的问题,简单问题。这种情况下...
1、之前的方法并没有显式地将TKGC构造为一种增量学习问题——使模型能够适应训练数据的变化并能有效保留之前所学。它们将TKGC任务简单构造成KGC任务,仅仅在新的KG快照上对模型进行微调,导致灾难性遗忘。这点我不能苟同,既然在新的时间步下,过去的数据相对于当前已经无意义了。我就算把之前所学全都忘了,从新随机...

HyperspherE: An Embedding Method for Knowledge Graph Completion Based on HypersphereKnowledge graph completion (KGC) aims to predict missing facts by mining information already present in a knowledge graph (KG). A general solution for KGC task is embedding facts in KG into a low-dimensional ...
解码器:解码器就是某个事实的真实性的打分函数,文中直接用非时序KGC的打分方法,如式(2)所示。论文分别用ComplEx和TransE作为DE和HyTE的解码器。 评价指标 标准TKGC评价指标就是用Hits@k等,在某个KG快照上进行,如论文式 (3)。 而增量TKGC的评价指标需要评估两个方面: ...
In this work, we propose a Sequence Embedding with Adversarial learning approach (SEwA) for zero or low resource KGC. It transform the KGC into a sequence prediction problem by making full use of inherently link structure of knowledge graph and resource-easy-to-transfer feature of adversarial ...
