摘要:

本文提出了sandra,一个结合向量表示与演绎推理的神经符号推理器。Sandra构建了一个受本体约束的向量空间,并在其上进行推理。该推理器的几何特性使其能够与神经网络结合,弥合了与符号知识表示之间的差距。Sandra基于Description and Situation (DnS)本体设计模式,即框架语义学的一种形式化。给定一组事实(一个情境),它允许推断所有可能的视角(描述),从而为其提供合理的解释,即使在不完整信息存在的情况下也是如此。我们证明了我们的方法在DnS模型下是正确的。我们在两个不同任务及其标准基准上进行了实验,证明在不增加复杂性的情况下,sandra (i) 优于所有基线,(ii) 在分类过程中提供可解释性,以及 (iii) 允许对先验设计的向量空间进行控制。

英文摘要:

This paper presents sandra, a neuro-symbolic reasoner combining vectorial representations with deductive reasoning. Sandra builds a vector space constrained by an ontology and performs reasoning over it. The geometric nature of the reasoner allows its combination with neural networks, bridging the gap with symbolic knowledge representations. Sandra is based on the Description and Situation (DnS) ontology design pattern, a formalization of frame semantics. Given a set of facts (a situation) it allows to infer all possible perspectives (descriptions) that can provide a plausible interpretation for it, even in presence of incomplete information. We prove that our method is correct with respect to the DnS model. We experiment with two different tasks and their standard benchmarks, demonstrating that, without increasing complexity, sandra (i) outperforms all the baselines (ii) provides interpretability in the classification process, and (iii) allows control over the vector space, which is designed a priori.
