Use of the Japio Technical Field Dictionaries and Commercial Rule-based Engine for NTCIR-PatentMT.

Japio performs various patent-related translation businesses, and owns the original patent-document-derived bilingual technical term database (Japio Terminology Database) to be used by the translators. Currently the database contains more than 1,900,000 J-E bilingual technical terms. The Japio Technical Field Dictionaries (technical-field-oriented machine translation dictionaries) are created from the Japio Terminology Database based on each entry’s frequency in the bilingual patent document corpora which are also compiled by Japio. Japio applied the Japio Technical Field Dictionaries to a commercial machine translation engine for the NTCIR9PatentMT (JE and EJ subtasks).
