Collaborative Research:CI-P: Creation of an annotated repository of multilingual and multigenre code switched data for several language pairs

语码转换（Code switching，简称CS）是指使用同一种语言的双语者在他们的共同语言之间来回切换的一种常见行为。CS发生在所有类型的交流中，在不同的语言表征层面上。当输入信号中有其他语言时，即具有CS现象的数据，为单一语言训练的计算算法就会失败。研究CS处理的一个主要障碍是缺乏大型、准确注释的CS数据语料库。这个计划提案的目的是为一个大型的一致标注的数据存储库创建框架，该存储库将针对7种不同的语言，用不同粒度级别的特性进行标注。在计划授权的过程中，我们计划举办一个社区研讨会，以确保我们在存储库中解决了他们的需求。我们将与社区合作，以准备完整的CRI提案。这些数据将为计算语言学研究带来变革，因为它将为自适应学习算法提供一个测试平台，在处理非常多样化的数据源方面具有显著的鲁棒性，并为真正的多语言处理创建一个框架。此外，它将对社会语言学家解释CS的方式产生直接影响，从而产生更强大和可复制的概括。对言语交际的研究将有助于认识双语者在开发其语言储备方面的创造力。CS储存库将使许多相互关联的领域能够进行新的研究。这项研究将有助于提高人们对双语/多语的普遍认识。

Code switching (CS) is the term used to describe a common practice among bilingual speakers of a given language pair in which the speakers switch back and forth between their common languages. CS occurs in all genres of communication, and at different levels of linguistic representation. Computational algorithms trained for a single language fail when the input has other languages in the signal i.e. data with CS phenomena. One major barrier to research on processing CS is the lack of large, accurately annotated corpora of CS data. This planning proposal aims at creating the framework for a large consistently annotated data repository that will target 7 different languages annotated with features at different levels of granularity. In the course of the planning grant, we plan to hold a community workshop to ensure that we are addressing their needs in the repository. We will work with the community in order to prepare the full CRI proposal. This data will be transformative for computational linguistics research as it will provide a testbed for adaptive learning algorithms, lead to significant robustness in handling very diverse data sources, and create a framework for genuine multilingual processing. Moreover, it will have a direct impact on the way sociolinguists account for CS leading to more robust and replicable generalizations. Research on CS will help acknowledge the creativity of bilinguals in exploiting their verbal repertoire. The CS repository will enable new research in many interconnected fields. This research will contribute to raising general awareness of bi/multilingualism.
