Probabilistic Interval-Valued Neutrosophic for Assessment of University Language Service Talent Development of Hainan Province Free Trade Port

The need for strong, globally focused language services has increased significantly as Hainan Province develops its Free Trade Port (FTP). Hainan's universities are essential to this development because they develop talent, offer translation and interpretation services, and promote intercultural dialogue. Using uncertainty framework, this study attempts to assess the present state and caliber of university language service development in support of the FTP. The availability of multilingual services, the caliber of translations, assistance for overseas students, and the incorporation of digital language aids were among the ten assessment criteria that were determined. We use the Probabilistic Interval-Valued Neutrosophic Hesitant Fuzzy Set (PIVNHFS) to solve uncertainty information. The contributions, preparedness, and innovation levels of ten university programs and service centers were evaluated. The results point to both service capacity strengths and weaknesses, especially with relation to adopted digital tools, applied translation, and cooperation with industry stakeholders. Considering regional growth and economic globalization, the assessment supports language services capacity building and strategic planning.
