Chinese to English Machine Translation for Patent Documents
Traditional labor intensive translation work depends a lot on iterative human efforts in revision before production of the final translation. ChilinTrans aims at providing computer-aided patent translation service for the customer to save 50% or more of the cost in the traditional patent translation field.
