Charles Translator: A Machine Translation System Between Ukrainian and Czech to Aid Refugees and Facilitate Communication

Conceptos Básicos

Charles Translator is a machine translation system developed to quickly provide high-quality translation between Ukrainian and Czech in order to mitigate the language barrier faced by Ukrainian refugees in the Czech Republic following the Russian invasion of Ukraine.

Resumen

The paper presents Charles Translator, a machine translation system developed between Ukrainian and Czech to aid communication during the refugee crisis caused by the Russian invasion of Ukraine in 2022.
The key highlights are:

The system was developed rapidly in the spring of 2022 with the help of volunteer data providers to meet the urgent demand for such a service.
It uses the Transformer architecture with iterated block back-translation, allowing for efficient use of monolingual training data.
The training data was collected from a variety of sources, including parallel corpora and monolingual data for back-translation.
Two test sets were created to evaluate the system's performance on the types of communication needed by refugees, covering formal, news, and personal domains.
The system was deployed as a web interface and an Android app, supporting Cyrillic-Latin script transliteration.
The system has been used extensively, with over 30,000 translation requests per day in the Ukrainian-to-Czech direction and 12,000 in the other direction.
Future plans include adapting the model for educational applications to support the integration of Ukrainian children into the Czech school system.

Estadísticas

By April 1, 2023, more than 504,000 Ukrainians had been granted temporary protection in the Czech Republic, of whom more than 325,000 had applied for an extension of their refugee status beyond March 2023.
The Charles Translator system showed the following usage statistics in September 2023:

In the Ukrainian→Czech direction, there was an average of 30,000 translation requests per day and about two million characters translated per day.
In the Czech→Ukrainian direction, there were approx. 12,000 requests per day and a total of approx. one million characters translated per day.

Citas

"Our motivation to develop such a service, apart from the wish to help reduce the language (and social) barrier between the refugees and the Czech society, is based on several convenient factors: (i) our previous long-term scientific experience in the field of machine translation (MT) and the existence of an appropriate MT method, (ii) the proximity of the two Slavic languages in question, and (iii) the availability of resources: the possibility of obtaining training data from multiple volunteer subjects and the willingness of many researchers to prioritize this line of research, leading to a quick solution with a quick implementation process."
"The translation systems available to the public during the conflict outbreak translated only indirectly between Czech and Ukrainian by pivoting through English. This approach does not take advantage of the typological affinity of the two languages, such as the high inflection with rich morphology enabling great flexibility of word order, pro-drop, partial lexical similarity, e.g. m˚
uj d˚
um – мiй дiм (my house), chladn´
a zima – xолодна зима (cold winter), kr´
atk´
e vlasy – коротке волосся (short hair) and syntactic similarities."

How can the Charles Translator system be further improved to handle more complex language phenomena, such as idioms and cultural references, to enhance the quality of translations for refugees?

To enhance the quality of translations for refugees, the Charles Translator system can be further improved in several ways:

Idioms and Cultural References: Implement a specialized module that focuses on capturing and translating idiomatic expressions and cultural references accurately. This module can include a database of common idioms and cultural nuances specific to Ukrainian and Czech languages.

Contextual Understanding: Develop a feature that analyzes the context of the text to provide more accurate translations. This can involve incorporating machine learning algorithms to understand the context in which certain phrases or words are used.

User Feedback Integration: Implement a feedback loop where users can provide input on the translations they receive. This feedback can be used to continuously improve the system's understanding of idiomatic expressions and cultural references.

Collaboration with Linguists: Collaborate with linguists and cultural experts to fine-tune the translation models specifically for handling complex language phenomena. Linguists can provide insights into the nuances of language that are challenging for machine translation systems.

Continuous Training: Regularly update the training data with new examples of idioms and cultural references to ensure that the system stays up-to-date with evolving language usage.

What other applications or domains could the Charles Translator system be adapted for beyond the current refugee communication and educational use cases?

The Charles Translator system has the potential to be adapted for various applications and domains beyond refugee communication and education:

Business and Commerce: The system can be used for translating business documents, contracts, and communication between companies operating in both Ukrainian and Czech-speaking regions.

Tourism and Hospitality: Adapt the system for translating travel guides, hotel information, and communication between tourists and service providers in both languages.

Legal and Government Services: Implement the system for translating legal documents, government forms, and communication between legal entities and individuals in need of legal assistance.

Healthcare: Develop a version of the system tailored for translating medical documents, prescriptions, and communication between healthcare providers and patients who speak Ukrainian and Czech.

Media and Entertainment: Use the system for translating subtitles for movies, TV shows, and online content to cater to audiences in both languages.

Cross-Cultural Communication: Offer the system for facilitating communication in multicultural settings, conferences, and events where Ukrainian and Czech speakers interact.

Given the rapid development and deployment of the Charles Translator system, what lessons can be learned about the challenges and best practices for building and deploying machine translation systems in response to urgent societal needs?

Lessons learned from the development and deployment of the Charles Translator system for urgent societal needs include:

Agile Development: Emphasize agile development methodologies to quickly iterate on the system based on user feedback and evolving requirements.

Collaboration: Foster collaboration with language experts, volunteers, and organizations to gather high-quality training data and ensure the system meets the specific needs of the target users.

Ethical Considerations: Prioritize user privacy and data security by anonymizing personal information and providing users with control over their data.

User-Centric Design: Design user interfaces that are intuitive and accessible, considering the diverse needs of the target user groups.

Continuous Improvement: Implement mechanisms for continuous monitoring, evaluation, and improvement of the system to maintain translation quality and relevance over time.

Scalability: Ensure that the system architecture is scalable to handle increasing demand and usage, especially during peak periods.

Community Engagement: Engage with the community to raise awareness about the system, gather feedback, and build a supportive user base for long-term sustainability.
