摘要:

我们解决的问题的词性标注(POS)的语言代码转换(CS)的上下文中。语篇转换是说话者在两种语言或同一语言的变体之间进行转换的现象,分别称为语篇内语篇转换或语篇间语篇转换。考虑到最先进的单语NLP技术,处理CS数据在内部数据中尤其具有挑战性,因为这种技术适合于一次处理一种语言。在本文中,我们探讨了多种策略,应用国家的最先进的POS标记CS数据。我们调查的景观在两个CS语言对,西班牙语-英语和现代标准阿拉伯语-阿拉伯语方言。我们比较了使用两个POS标签与统一的标签CS数据上训练。我们的研究结果表明,应用机器学习框架,使用两个国家的最先进的POS标签实现了更好的性能相比,我们调查的所有其他方法。

英文摘要:

We address the problem of Part of Speech tagging (POS) in the context of linguistic code switching (CS). CS is the phenomenon where a speaker switches between two languages or variants of the same language within or across utterances, known as intra-sentential or inter-sentential CS, respectively. Processing CS data is especially challenging in intra-sentential data given state of the art monolingual NLP technology since such technology is geared toward the processing of one language at a time. In this paper we explore multiple strategies of applying state of the art POS taggers to CS data. We investigate the landscape in two CS language pairs, Spanish-English and Modern Standard Arabic-Arabic dialects. We compare the use of two POS taggers vs. a unified tagger trained on CS data. Our results show that applying a machine learning framework using two state of the art POS taggers achieves better performance compared to all other approaches that we investigate.
