摘要:

大规模的知识库目前已经达到了令人印象深刻的规模;然而,这些知识库仍然远远没有完成。此外,现有的知识库补全方法大多只考虑实体之间的直接联系,忽略了关系路径语义一致性的重要影响。本文研究了如何充分利用关系路径的附加语义,将知识库中的实体和关系更好地嵌入到不同的低维空间中,提出了一种关系路径嵌入的组合学习模型(RPE)。具体地说,通过对应的关系和路径投影,RPE可以同时将每个实体嵌入到两种类型的潜在空间中。本文还提出了将传统的关系型约束扩展到路径型约束的方法。实验结果表明,与现有算法相比,该模型取得了显著的一致性改进。

英文摘要:

Large-scale knowledge bases have currently reached impressive sizes; however, these knowledge bases are still far from complete. In addition, most of the existing methods for knowledge base completion only consider the direct links between entities, ignoring the vital impact of the consistent semantics of relation paths. In this paper, we study the problem of how to better embed entities and relations of knowledge bases into different low-dimensional spaces by taking full advantage of the additional semantics of relation paths, and we propose a compositional learning model of relation path embedding (RPE). Specifically, with the corresponding relation and path projections, RPE can simultaneously embed each entity into two types of latent spaces. It is also proposed that type constraints could be extended from traditional relation-specific constraints to the new proposed path-specific constraints. The results of experiments show that the proposed model achieves significant and consistent improvements compared with the state-of-the-art algorithms.
