摘要:

我们解决的任务,自动评分的能力的候选人的文本特征的基础上,从自动语音识别(ASR)transmitting在异步视频求职面试(AVI)。关键的挑战是如何构建问题和答案之间的依赖关系,并进行语义级的互动,为每个问答(QA)对。然而,目前对AVI的研究大多集中在如何更好地表示问题和答案上,而忽略了问题和答案之间的依赖信息和相互作用,这对QA评估至关重要。在这项工作中,我们提出了一种分层推理图神经网络(HRGNN)来自动评估问答对。具体而言,我们构建了一个句子级关系图神经网络来捕获问题和答案之间的句子依赖信息。基于这些图,我们采用语义级推理图注意力网络模型的互动状态的当前QA会话。最后,我们提出了一个门控递归单元编码器来表示最终预测的时间问答对。在CHNAT(一个真实世界的数据集)上进行的实证结果验证了我们提出的模型显着优于基于文本匹配的基准模型。烧蚀研究和10个随机种子的实验结果也表明了我们的模型的有效性和稳定性。

英文摘要:

We address the task of automatically scoring the competency of candidates based on textual features, from the automatic speech recognition (ASR) transcriptions in the asynchronous video job interview (AVI). The key challenge is how to construct the dependency relation between questions and answers, and conduct the semantic level interaction for each question-answer (QA) pair. However, most of the recent studies in AVI focus on how to represent questions and answers better, but ignore the dependency information and interaction between them, which is critical for QA evaluation. In this work, we propose a Hierarchical Reasoning Graph Neural Network (HRGNN) for the automatic assessment of question-answer pairs. Specifically, we construct a sentence-level relational graph neural network to capture the dependency information of sentences in or between the question and the answer. Based on these graphs, we employ a semantic-level reasoning graph attention network to model the interaction states of the current QA session. Finally, we propose a gated recurrent unit encoder to represent the temporal question-answer pairs for the final prediction. Empirical results conducted on CHNAT (a real-world dataset) validate that our proposed model significantly outperforms text-matching based benchmark models. Ablation studies and experimental results with 10 random seeds also show the effectiveness and stability of our models.
