Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to Japanese language processing, and more particularly to a character processing apparatus for rapidly creating a correctly written sentence in Kana-Kanji conversion.

[0002]

2. Description of the Related Art Generally, Japanese input in a character processing device such as a Japanese word processor is performed by using kana-kanji conversion. The conversion candidates for this Kana-Kanji conversion are created using a word dictionary that stores information about words such as reading, notation, and part of speech. Further, such a character processing device is provided with a registered word dictionary that allows a user to register a word (hereinafter referred to as an unknown word) that is not stored in the word dictionary. If an unknown word is registered in this dictionary, that word will appear in the kana-kanji conversion candidates, and the conversion result can be obtained efficiently.

[0003]

However, in the case of adding to an already created document or creating those related documents, it is considered that the creator registered when the created document was created. In many cases, you cannot get a registered word dictionary. Especially when the document is a document created by another person. Therefore, when an unknown word of a created document is used during new input, the unknown word does not become a kana-kanji conversion candidate and the conversion result cannot be obtained efficiently.

It is an object of the present invention to provide a character processing device which allows a user to easily register an unknown word used in a document that has already been created.

[0005]

In order to achieve the above object, the present invention stores the information of the word including the display character string corresponding to the input means for inputting the character and the reading of the word. And a kana-kanji conversion means for converting the kana character string input by the input means into the notation character string by referring to the word dictionary means, and information of words not stored in the word dictionary means. A registered word dictionary means for registering a word, an unknown word extracting means for extracting a word not stored in the word dictionary means or the registered word dictionary means from the document created by the kana-kanji conversion, and the extracted word. And unknown word registration means for registering in the registered word dictionary.

[0006]

According to the present invention configured as described above, the unknown word extracting means extracts a word which is not stored in the word dictionary means or the registered word dictionary means from the prepared document, and the extracted word is Since it can be registered in the registered word dictionary by the unknown word registration means, the user can extract an unknown word that already appears in a document and register the unknown word. This makes it possible to improve conversion efficiency when adding or changing the document or creating a related document.
