摘要:

在多轮知识导向对话中,不同轮选择的知识之间的差异往往为知识选择提供了潜在的线索,而这一点在以往的研究中被忽略了。在本文中,我们提出了一个差异意识的知识选择方法。它首先计算在当前轮提供的候选知识句子和在先前轮中选择的候选知识句子之间的差异。然后,将差异信息与上下文信息融合或分离,以便于最终的知识选择。自动,人工观察和交互式评估表明,我们的方法能够更准确地选择知识,并生成更多信息的响应,显着优于最先进的基线。这些代码可在https://github.com/chujiezheng/DiffKS上获得。

英文摘要:

In a multi-turn knowledge-grounded dialog, the difference between the knowledge selected at different turns usually provides potential clues to knowledge selection, which has been largely neglected in previous research. In this paper, we propose a difference-aware knowledge selection method. It first computes the difference between the candidate knowledge sentences provided at the current turn and those chosen in the previous turns. Then, the differential information is fused with or disentangled from the contextual information to facilitate final knowledge selection. Automatic, human observational, and interactive evaluation shows that our method is able to select knowledge more accurately and generate more informative responses, significantly outperforming the state-of-the-art baselines. The codes are available at https://github.com/chujiezheng/DiffKS.
