摘要:

语义解析将自然语言的话语映射为逻辑形式,这是许多高级自然语言处理问题的基础。语义解析器通过深度神经网络获得性能提升,但继承了对抗性示例的漏洞。在本文中,我们提供了在存在对抗攻击的语义解析器的鲁棒性的实证研究。形式上,语义解析的对手被认为是扰动的话语-LF对,其话语具有与原始话语完全相同的含义。提出了一种基于已有基准语料库的可扩展鲁棒性测试集构造方法。我们的研究结果回答了五个研究问题,在衡量最先进的解析器的鲁棒性测试集的性能,并评估数据增强的效果。

英文摘要:

Semantic parsing maps natural language (NL) utterances into logical forms (LFs), which underpins many advanced NLP problems. Semantic parsers gain performance boosts with deep neural networks, but inherit vulnerabilities against adversarial examples. In this paper, we provide the empirical study on the robustness of semantic parsers in the presence of adversarial attacks. Formally, adversaries of semantic parsing are considered to be the perturbed utterance-LF pairs, whose utterances have exactly the same meanings as the original ones. A scalable methodology is proposed to construct robustness test sets based on existing benchmark corpora. Our results answered five research questions in measuring the sate-of-the-art parsers' performance on robustness test sets, and evaluating the effect of data augmentation.
