摘要:

近年来,许多研究将外部知识引入到基于特征的模型中,以提高中文关系抽取的性能。然而,这些方法往往忽略了汉字的内部信息,不能过滤掉外部知识的噪声信息。为了解决这些问题,我们提出了一个混合视图专家框架(MoVE)动态学习多视图特征的中文关系抽取。该框架结合了汉字的内部和外部知识,能够更好地捕捉汉字的语义信息。为了证明所提出的框架的有效性,我们在不同领域的三个真实世界的数据集上进行了广泛的实验。实验结果表明,我们提出的框架一致和显着的优越性和鲁棒性。我们的代码和数据集将发布在:https://gitee.com/tmg-nudt/multi-view-of-expert-for-chineserelation-extraction

英文摘要:

Recently, many studies incorporate external knowledge into character-level feature based models to improve the performance of Chinese relation extraction. However, these methods tend to ignore the internal information of the Chinese character and cannot filter out the noisy information of external knowledge. To address these issues, we propose a mixture-of-view-experts framework (MoVE) to dynamically learn multi-view features for Chinese relation extraction. With both the internal and external knowledge of Chinese characters, our framework can better capture the semantic information of Chinese characters. To demonstrate the effectiveness of the proposed framework, we conduct extensive experiments on three real-world datasets in distinct domains. Experimental results show consistent and significant superiority and robustness of our proposed framework. Our code and dataset will be released at: https://gitee.com/tmg-nudt/multi-view-of-expert-for-chineserelation-extraction
