AI总结:

本文研究阿拉伯方言文本规范化(CODAfication)任务,通过在预训练序列到序列模型中利用方言识别信息,提升了五种城市方言的规范化性能,并公开了代码、数据和模型。

摘要:

阿拉伯方言是阿拉伯语母语者在日常交流中使用的主要口语。社交媒体平台的兴起显著扩大了其作为书面语言的使用。然而,阿拉伯方言没有标准正字法。这一点,加上社交媒体上用户生成内容中固有的噪声,给处理阿拉伯方言的NLP应用带来了重大挑战。在本文中,我们探索并报告了CODAfication任务,该任务旨在将阿拉伯方言规范化为阿拉伯方言常规正字法(CODA)。我们使用了一个包含多种阿拉伯方言的独特平行语料库,重点关注五种主要城市方言。我们在CODAfication任务上对新开发的预训练序列到序列模型进行了基准测试。我们进一步表明,使用方言识别信息提高了所有方言的性能。我们公开了我们的代码、数据和预训练模型。

英文摘要:

Dialectal Arabic is the primary spoken language used by native Arabic speakers in daily communication. The rise of social media platforms has notably expanded its use as a written language. However, Arabic dialects do not have standard orthographies. This, combined with the inherent noise in user-generated content on social media, presents a major challenge to NLP applications dealing with Dialectal Arabic. In this paper, we explore and report on the task of CODAfication, which aims to normalize Dialectal Arabic into the Conventional Orthography for Dialectal Arabic (CODA). We work with a unique parallel corpus of multiple Arabic dialects focusing on five major city dialects. We benchmark newly developed pretrained sequence-to-sequence models on the task of CODAfication. We further show that using dialect identification information improves the performance across all dialects. We make our code, data, and pretrained models publicly available.
