Use of the Technical Field-Oriented User Dictionaries.

Japio performs various patent-related translation businesses, and owns the original patent-documentderived bilingual technical term database (Japio Terminology Database) to be served for the translators. Currently the database contains more than 780,000 J-E technical terms. To adapt the database to the Patent Translation Task, Japio compiled machine translation dictionaries from it. 34 technical field-oriented dictionaries were created based on Japio’s original technical fields. Terms are evaluated and selected according to their actual frequency in the bilingual patent document corpus of concerned technical field.
