摘要:

许多重要的问题都可以用知识图谱来表示。表示学习已被证明对转换推理非常有效,在转换推理中,人们需要对已经观察到的实体做出新的预测。这对于属性图(其中每个实体都有一个初始特征向量)和非属性图(其中唯一的初始信息来自与其他实体的已知关系)都是如此。对于样本外推理,需要对训练时看不到的实体进行预测,许多先前的工作考虑了属性图。然而,令人惊讶的是,这个问题对于非属性图的探索不足。在本文中,我们研究了非属性知识图谱的样本外表示学习问题,为这项任务创建基准数据集,开发几个模型和基线,并提供实证分析和比较所提出的模型和基线。

英文摘要:

Many important problems can be formulated as reasoning in knowledge graphs. Representation learning has proved extremely effective for transductive reasoning, in which one needs to make new predictions for already observed entities. This is true for both attributed graphs(where each entity has an initial feature vector) and non-attributed graphs (where the only initial information derives from known relations with other entities). For out-of-sample reasoning, where one needs to make predictions for entities that were unseen at training time, much prior work considers attributed graph. However, this problem is surprisingly under-explored for non-attributed graphs. In this paper, we study the out-of-sample representation learning problem for non-attributed knowledge graphs, create benchmark datasets for this task, develop several models and baselines, and provide empirical analyses and comparisons of the proposed models and baselines.
