面向自然语言理解的语义感知推理网络

Semantics-Aware Inferential Network for Natural Language Understanding

Shanghai Jiao Tong University(上海交通大学)

摘要:

对于自然语言理解任务,无论是机器阅读理解还是自然语言推理,语义感知和推理都是相关建模的有利特征,以获得更好的理解性能。因此,我们提出了一个语义感知推理网络(SAIN),以满足这样的动机。SAIN的推理模块以显式语境化语义作为补充输入,通过注意力机制对语义线索进行一系列推理。通过串接这些步骤,推理网络有效地学习执行迭代推理,该迭代推理结合了显式语义和上下文表示。在良好的预训练语言模型作为前端编码器方面,我们的模型在包括机器阅读理解和自然语言推理在内的11个任务上取得了显着的改进。

英文摘要:

For natural language understanding tasks, either machine reading comprehension or natural language inference, both semantics-aware and inference are favorable features of the concerned modeling for better understanding performance. Thus we propose a Semantics-Aware Inferential Network (SAIN) to meet such a motivation. Taking explicit contextualized semantics as a complementary input, the inferential module of SAIN enables a series of reasoning steps over semantic clues through an attention mechanism. By stringing these steps, the inferential network effectively learns to perform iterative reasoning which incorporates both explicit semantics and contextualized representations. In terms of well pre-trained language models as front-end encoder, our model achieves significant improvement on 11 tasks including machine reading comprehension and natural language inference.
