There are six dictionaries altogether. The 1000 series contain words which are consist of most frequent 1000 kanji (approximately, kyoiku kanji) while the 2000 series montain words which are consist of the most frequent 2000 kanji. (joyo kanji) In eitehr series, Minus-Dict contains entries which have missing kana. (e.g. "ぎんこ" is registered as a reading of 銀行 or "おな" is registered as a reading of 女) Voicing-Dict contains errors on voicing. (e.g. "ちが" is registered as a reading of 地下) Plus-Dict contains words which have extraneous long vowels. (e.g. "じしょう" is registered as a reading of 辞書)
A user needs to open necessary dictionaries to handle errorneous inputs. This is done in 環境設定パレット in kotoeri, and in Micorsoft IME-2000 property page of Windows 98/2000.

ATOK is a commercial IME developed and sold by Just System. It is available for both Windows and Macintosh. We have packaged a set for ATOK13 for Windows.
ATOK allows users to generate their own main dictionaries. Two main dictionaries for 1000-kanji level and 2000-kanji level have been generated. (i.e. 1000-Main-Dict and 2000-Main-Dict) For example, when you use 1000-Main-Dict, instead of the default main dictionary, no kanji beyond 1000-level will ever appear in the conversion process. Hence, the number of conversion possibilities becomes much smaller and manageable.

Since there are different versions of ATOK is in use both on Windows and Macintosh, you may have to recompile dictionaries using Dictionary Utility Program which comes with the version of ATOK you are using.
