摘要

在本文中，我们将程序检索问题表述为图相似性问题。为此，我们首先将查询和程序片段分别明确表示为 AMR 和 CPG。然后，通过层内和层间关注机制，沿着图边传播节点对应关系，从而推断出细粒度的对应关系。此外，这种设计还能学习不同层次节点的对应关系，而这一点在以往的研究中大多被忽略。实验证明了 USRAE 的优越性。

Semantic similarity-based program retrieval: a multi-relational graph perspective

In this paper, we formulate the program retrieval problem as a graph similarity problem. This is achieved by first explicitly representing queries and program snippets as AMR and CPG, respectively. Then, through intra-level and inter-level attention mechanisms to infer fine-grained correspondence by propagating node correspondence along the graph edge. Moreover, such a design can learn correspondence of nodes at different levels, which were mostly ignored by previous works. Experiments have demonstrated the superiority of USRAE.
