Japio’s AI translation - Mainfeatures -1. Advanced AI translation technology (Transformer method)
The “Transformer method”, a second-generation neural machine translation technology,
improves syntax recognition accuracy. Long sentences, which are often used in patentdocuments, can be translated with higher accuracy than conventional methods.

Japio’s AI translation - Mainfeatures -2. Training data, specialized for patent translation

By learning AI translation with a large amount of patent bilingual texts collected uniquely by Japio,
difficult patent texts can be translated in an accurate and readable form.
Whether in Japanese, English or other languages, writing of patent document is very unique.
Japio’s AI translation can reproduce its uniqueness, because training data is oriented to patenttranslation.

Japio’s AI translation - Mainfeatures -3. AI with patent translators know-how“X-STEP” is a machine translation framework originally developed by Japio to translate patentdocument data in XML format published by national patent offices. In order to make thetranslation results of long claims accurate and easy to understand, it has a function ofautomatic pre-editing and high reproducibility in the translation of superscripts and subscripts
frequently found in patent documents.

Japio’s AI translation - Mainfeatures -4. NMT in combination with SMT
Because AI translation is a developing technology, there is a certain probability that phrases
written in the original text will not be translated (incomplete translation) or words not written
in the original text will be translated (unnecessary translation). Therefore, we have adopted amethod of checking the AI translation for errors and using statistical translation technology toback up any noticeable incomplete translation or unnecessary translation.

Japio’s AI translation - Mainfeatures -5. A wide variety of languages
Japio's AI translation system allows machine translation from English, Chinese, Taiwanese, Korean,French, Russian, German into Japanese. This covers more than 92% of the languages used in theworld's stored documents. It also covers all the languages used in the top 10 documents cited bythe IP5 (IP Offices of Japan, the U.S., Europe, China, and Korea) over the past 10 years.

Japio’s AI translation - Mainfeatures -6. Confidentiality
SSL encryption communication is used to communicate from the customer's environment
to the translation server so that customers can safely translate patent documents
before filing. When translating text other than published publication data, neither theoriginal text nor the translation results are recorded in the translation server.
