Knowledge graphs (KGs) have been applied to many semantic-driven applications, including knowledge interchange and semantic inference. However, most KGs are far from complete and are growing rapidly. Although significant progress has been made in the symbolic representation learning of KGs with structural information, the textual knowledge that plays a crucial role in relation prediction is underutilized, and the issues of redundancy and noise path remain to be settled. In this paper, a Path-based Attribute-aware Representation Learning model (PARL) has been proposed to perform path denoising and path representation learning for the relation prediction task. We develop a novel text-enhanced relation prediction architecture, which interactively learns KG structural and textual representations to vary the sparsity and reliability of KG. Moreover, a path denoising algorithm is presented to emphasize paths with rich information and reduce the impact of redundancy and noise path. Experiments on a public dataset demonstrate that PARL consistently outperforms state-of-the-art methods on relation prediction and KG completion tasks.
