Digital Language Services: Evolution, Challenges, Opportunities, and Ethical Implications

Digital language services (DLS), powered by advanced technologies, have become effective instruments for promoting cooperation and communication across linguistic boundaries. We selected 25 publications to guide this study based on both inclusion and exclusion criteria. Through a systematic review based on the framework of PRISMA, it is revealed that there is a huge potential for innovation and progress in the intelligent language service industry, even while there are still difficulties and ethical concerns unaddressed. We can fully utilize Digital language services to construct and maintain a more interconnected and inclusive world by tackling these obstacles and utilizing cutting-edge technologies. The collaboration between humans and technologies also plays an important role in DLS. It is expected that humans will improve the development of DLS by assisting with technologies rather than replacing them. This study formulates a solid foundation for future researchers and practitioners, based on which numerous research directions can be delved into shortly. The findings can be applied to various fields such as education, marketing, social studies, and computer science.
