Chinese-English Machine Translation System.
Wang, William S-Y; And Others
The report documents results of a two-year R&D effort directed at the completion of a prototype system for Chinese-English machine translation of S&T literature. The system, designated QUINCE, accepts Chinese input exactly as printed, with no pre-editing of any kind, and produces English output on experimental basis. Coding of Chinese text via Chinese Teleprinter System (Model 600D) and subsequent conversion to Standard Telegraphic Code for a direct input to the computer have been successfully completed. Manual keypunching and coding have been completely eliminated. Error rate from coding raw Chinese Texts into STC is less than .03 percent. Operation of QUNICE System is a six-step process, beginning with INPUT followed by analysis of Chinese (SEGMENTATION, LEXICON, GRAMMARS) and synthesis in English (TRANSFER, EXTRACT). Machine translation proceeds sentence by sentence as a global context. Five grammars are applied in a specific sequence. The system of multiple grammars, replacing a single monolithic grammar, has been in successful operation since May 1974. The lexical data base now contains a total of 82,330 entries in CHIDIC. A dictionary of 35,000 lexical items on nuclear physics (PHYDIC) has been machine-selected from CHIDIC. The system's design is stable, immutable, and highly machine independent. Programming strategy emphasizes the requirements of flexibility, reliability, compactness, efficiency, and portability. (Author/KM)
