Now available for portable devices such as electronic dictionaries for Sharp and Casio and devices such as the iPhone/iPod Touch and Android-powered mobile phones.

The CJK Dictionary Institute maintains a comprehensive Japanese-English bilingual, bidirectional database of over 1,000,000 technical terms covering a broad spectrum of fields ranging from computer science to biotechnology. This database is currently being used by some of the world's leading companies such as Fujitsu, Microsoft, and Casio. Below is a list of domains covered, and a data sample.

This database is being used in a variety of applications and software products, such as:

• Machine translation dictionaries.
• Information retrieval applications for accurate term recognition and indexing.
• NLP tools like morphological analyzers and tokenizers.
• Handheld electronic dictionaries, such as in Casio's high end Exword GT series and Sharp's Brain series.
• In CD-ROM format, as in Logovista's Electronic Dictionary Series.
• Smart phone applications.

We are currently working on various new domains and expanding the existing ones. If there is a specific domain you need, or if you would like a list of subdomains, please contact CJKI at the email address shown at the top of this page.
