Medical translation is highly professional, involving many professional vocabulary and medical terms, which requires unlimited expansion of their medical corpora and terminologies. Our AI technology has accumulated a lot in big data, natural semantic analysis, machine learning and deep neural network. Our engine is based on billion level medical massive data and algorithms, which can deeply understand and optimize the translation system of medical subfields (such as preclinical, clinical, drug production, pharmacovigilance, diagnostic equipment, experimental consumables, etc.), and continuously maintain the breadth and coverage of medical industry knowledge. Applying AI to medical translation can not only reduce costs, but also improve efficiency and accuracy.
