Aspect term extraction (ATE) aims at identifying the aspect terms that are expressed in a sentence. Recently, Seq2Seq learning has been employed in ATE and significantly improved performance. However, it suffers from some weaknesses, such as lacking the ability to encode the more informative information and integrate information of surrounding words in the encoder. The static word embeddings employed in ATE fall short of modeling the dynamic meaning of words. To alleviate the problems mentioned above, this paper proposes the information-augmented neural network (IANN) which is a novel Seq2Seq learning framework. In IANN, a specialized neural network is developed as the key module of the encoder, named multiple convolution with recurrence network (MCRN), to encode the more informative information and integrate information of surrounding words in the encoder. The contextualized embedding layer is designed to capture the dynamic word sense. Besides, the novel AO ({Aspect, Outside}) tags are proposed as the less challenging tagging scheme. A lot of experiments have been performed on three widely used datasets. These experiments demonstrate that the proposed IANN acquires state-of-the-art results and validate that the proposed IANN is a powerful method for the ATE task.

通过信息增强神经网络提取方面术语

方面术语提取(ATE)旨在识别句子中表达的方面术语。最近,Seq2Seq 学习已被用于 ATE 并显着提高了性能。然而,它存在一些弱点,例如缺乏对更多信息信息进行编码和在编码器中整合周围单词信息的能力。ATE 中使用的静态词嵌入无法对词的动态含义进行建模。为了缓解上述问题,本文提出了信息增强神经网络(IANN),这是一种新颖的 Seq2Seq 学习框架。在 IANN 中,开发了一个专门的神经网络作为编码器的关键模块,命名为带递归网络的多重卷积(MCRN),对更多信息信息进行编码,并在编码器中整合周围单词的信息。上下文嵌入层旨在捕捉动态词义。此外,小说AO({一个spect, O utside}) 标签被提出作为不太具有挑战性的标签方案。已经在三个广泛使用的数据集上进行了大量实验。这些实验表明,提议的 IANN 获得了最先进的结果,并验证了提议的 IANN 是 ATE 任务的强大方法。
