FOKS was originally constructed by Slaven Bilac as part of his PhD research at the Tokyo Institute of Technology. The original version is still available here and continues to be used for mobile phones. The current system was rebuilt by Lars Yencken, a current PhD student at the University of Melbourne, who works on maintaining and extending it.
FOKS is a Japanese-to-English dictionary which allows lookup by reading, and can correct for many common types of reading errors, in particular:
|Choice of reading||A single kanji character can have many possible readings, depending on the word it is in. FOKS still shows the right results if the wrong reading for a kanji is entered.
Example: 山車 /だし/ "festival float", searched for as "やまくるま", "やましゃ" or "さんしゃ".
|Vowel length||Learners often have trouble distinguishing between long and short vowels, especially if their native language does not make this distinction.
Example: 大阪 /おおさか/ "Osaka" searched for as "おさか".
|Palatalization||Learners often mistake palatalized sounds with their non-palatalized counterparts, and vice-versa.
Example: Confusing /りゅ/ and /る/.
Keitai (Cellular) Phone Interface
FOKS is accessible from a number of mobile phone interfaces, in particular EZWEB (WAP), I-mode or J-Sky access methods. Only phones able to display and input Japanese characters can be used. However, the interfaces have been tested in very limited fashion so there might be some problems depending on the make of your phone. If you find an error please contact firstname.lastname@example.org with a description of your problem. This interface is not actively being developed, and uses an older version of FOKS.
Following URLs can be used to access the respective interfaces:

FOKS is built from a number of freely available resources, and word frequency counts from a non-free corpus.
|Edict||Edict is a freely available Japanese-English dictionary, maintained by Jim Breen.|
|Compdic||A dictionary of computer terms.|
|Enamdict||A dictionary of proper nouns, such as place and person names.|
|Kanjidic||A dictionary of kanji readings and meanings.|
|Japan post gazetteer||A place hierarchy mined from Japanese postal districts.|
