Theory and Practice

Translation Lab Inc


Translation Lab Inc. is committed to avoiding reliance on personal anecdotes. Instead, we prioritize empirical evidence and academic theories. What defines the quality of translation? What embodies efficiency? What is the essence of translation technology? We relentlessly pursue these questions from a purely academic standpoint. Furthermore, we aim to present a vision for the future of translation and localization.

About us.

A translation and localization company that is a compact group of experts integrating translation technology, the backing of academic translation studies, and management knowledge to provide "translation" and "localization" based on empirical data.

Our main initiatives include:

  • Research and application in Translation Studies, translation theory, and linguistics.

  • Optimization of LLM (ChatGPT)translation memory, machine translation, post-editing, and QA tools.
