transcosmos launches AI training and annotation services leveraging talent across Japan and ASEAN

With a Human-in-the-Loop model built on employees, gig workers, and technologies, transcosmos delivers specialized AI data annotation services in Chinese, Japanese, and Korean

TOKYO, Dec. 25, 2025 /PRNewswire/ — transcosmos today announced the release of highly specialized AI training and data annotation services in Chinese, Japanese, and Korean languages. The service covers both specialized and company-specific data, regardless of volume size. Specialized areas include geography, history, finance, and engineering.

Until now, most AI data annotation—operations that label and tag image, voice, and text data for AI training—has focused on general data in English. With global AI demand rising, market needs are shifting toward multilingual, highly specialized data annotation services.

Leveraging its talent pool across Japan and ASEAN countries, transcosmos offers annotation services powered by professionals with deep expertise in CX domains such as contact centers, digital marketing, and system development. The service supports Chinese, Japanese, and Korean languages, covering markets with exceptionally high demands. Building on its network of talented employees and gig workers, specialists perform tasks including: data collection from documents and image sources in highly specialized fields; image, voice, and sentence labeling; emotion analysis; data extraction from contracts; and dialogue scenario creation and data generation.

Additionally, industry-experienced professionals annotate client-specific data—covering services, products, and customer inquiries—helping clients develop their own large language models (LLMs).

To ensure seamless operations and smooth and effective talent assignment, transcosmos is developing a resource management system that centrally stores information on utilization rate, areas of expertise, certifications, qualifications, and work history. transcosmos plans to register approximately 40,000 individuals, primarily employees. This system will enable managers to assign the right people to the right projects based on requirements, timelines, and skill sets.

Building on expertise and know-how gained through performing data collection and AI data annotation projects at transcosmos AI Lab, transcosmos will expand data annotation into more specialized areas and increase supported languages, leveraging its global network beyond ASEAN.
