Kyoto University & JST Trilingual Technical Term Dictionary (TriTechDict)


TriTechDict is a large-scale Japanese-English-Chinese technical term dictionary, containing about 3.3M entries. The original entries are from a Japanese-English dictionary provided by the Japan Science and Technology Agency (JST) (550k entries), and an English-Chinese dictionary provided by the Institute of Science and Technology information of China (ISTIC) (3.4M entries). We automatically translated the Japanese and Chinese entries in the original dictionaries into Chinese and Japanese, respectively, using a pivot based statistical machine translation system. Manual evaluation indicates that the accuracy of the constructed dictionary is 90%. The size of the constructed trilingual dictionary is about 3.3M after merging overlapped term pairs in the two translated dictionaries.

We release TriTechDict as a search interface, where users can judge the correctness of the entries, and enter more appropriate translations. We hope that the quality and coverage of the dictionary could be further improved by collective intelligence.
