Recent Advancements and Challenges of Turkic Central Asian Language Processing

Research in the NLP sphere of the Turkic counterparts of Central Asian languages, namely Kazakh, Uzbek, Kyrgyz, and Turkmen, comes with the typical challenges of low-resource languages, like data scarcity and a general lack of linguistic resources. However, in the recent years research has greatly advanced via collection of language-specific datasets and development of downstream task technologies. Aiming to summarize this research up until May 2024, this paper also seeks to identify potential areas of future work. To achieve this, the paper gives a broad, high-level overview of the linguistic properties of the languages, the current coverage and performance of already developed technology, application of transfer learning techniques from higher-resource languages, and availability of labeled and unlabeled data for each language. Providing a summary of the current state of affairs, we hope that further research will be facilitated with the considerations we provide in the current paper.
