摘要:

命名实体识别(NER)是自然语言处理(NLP)的一项基本任务。然而,大多数国家的最先进的研究主要是面向高资源的语言,如英语,并没有广泛应用于低资源的语言。在马来语中,相关的净入学率资源有限。在这项工作中,我们提出了一个数据集构建框架,该框架基于同源语言的标记数据集和迭代优化,构建了一个包含28,991个句子(超过384,000个标记)的马来语NER数据集(MYNER)。此外,为了更好地整合边界信息NER,我们提出了一个多任务(MT)模型与双向修订(双修订)机制马来语NER任务。具体来说,一个辅助任务,边界检测,引入到提高NER培训显式和隐式的方式。此外,提出了一种门控忽略机制来进行条件标签传输,并减轻辅助任务的错误传播。实验结果表明,我们的模型在MYNER上的基线上取得了可比的结果。本文中的数据集和模型将作为基准数据集公开发布。

英文摘要:

Named entity recognition (NER) is a fundamental task of natural language processing (NLP). However, most state-of-the-art research is mainly oriented to high-resource languages such as English and has not been widely applied to low-resource languages. In Malay language, relevant NER resources are limited. In this work, we propose a dataset construction framework, which is based on labeled datasets of homologous languages and iterative optimization, to build a Malay NER dataset (MYNER) comprising 28,991 sentences (over 384 thousand tokens). Additionally, to better integrate boundary information for NER, we propose a multi-task (MT) model with a bidirectional revision (Bi-revision) mechanism for Malay NER task. Specifically, an auxiliary task, boundary detection, is introduced to improve NER training in both explicit and implicit ways. Furthermore, a gated ignoring mechanism is proposed to conduct conditional label transfer and alleviate error propagation by the auxiliary task. Experimental results demonstrate that our model achieves comparable results over baselines on MYNER. The dataset and the model in this paper would be publicly released as a benchmark dataset.
