Abstract

PURPOSE:To improve the KANA (Japanese syllabary)/KANJI (Chinese character) conversion efficiency by changing some of only the inputted Japanese reading ways based on a specific rule and then performing the KANA/KANJI conversion again if no word of KATAKANA (square form of Japanese syllabary) equivalent to the inputted Japanese reading way is not contained in a word dictionary. CONSTITUTION:If no word of KATAKANA equivalent to the inputted Japanese reading is contained in a word dictionary 3, some of only the inputted Japanese reading ways are changed by a character string converting part 4 and a conversion rule storage part 5 based on a specific rule. A KANA/KANJI conversion means 2 performs the KANA/KANJI conversion again based on a character string of the changed Japanese reading way and defines an equivalent KATAKANA word if contained in the dictionary 3 as the result of conversion. Thus the variation of the KATAKANA description is absorbed so as to attain the KANA/KANJI conversion with high efficiency together with reduction of the dictionary capacity attained. Furthermore the KATAKANA descriptions can be unified.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a kana-kanji conversion method, and particularly to a katakana word conversion method.

[Conventional technology]

Regarding the kana-kanji conversion method, which converts the Japanese reading information input in hiragana into a character string containing kanji and kana, there have been various methods, but the method of checking against a word dictionary is based on the input character string. The idea was to extract words that match.

[Problem to be solved by the invention]

In the conventional kana-kanji conversion method, if the input character string and the word in the word dictionary do not match, conversion is impossible, especially in the case of katakana, which is expressed as "floppy", "floppy", "floppy", etc. If there are various words and not all are registered in the word dictionary,
The disadvantage is that it cannot be easily converted depending on the input method.

It is an object of the present invention to provide a kana-kanji conversion method that eliminates these drawbacks, absorbs variations in katakana orthography, and enables kana-kanji conversion.

[Means for Solving the Problems] The present invention provides a means for inputting Japanese reading information in hiragana, a word dictionary storing katakana and kanji word information, and a means for inputting Japanese reading information in hiragana. In the kana-kanji conversion method, which has a kana-kanji conversion means that compares it with a dictionary and converts it into a kanji-kana mixed character string, if the input katakana word corresponding to the input Japanese reading is not in the word dictionary, the input The method further includes means for changing a part of the Japanese reading according to a specific rule, and converts the Japanese reading into kana-kanji again using the character string of the changed Japanese reading and the kana-kanji converting means, so that the corresponding katakana word exists in the word dictionary. If this happens, that word is used as the conversion result.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention.

The second kana-kanji conversion method includes an input section 1, a kana-kanji conversion section 2, a word dictionary 3, a conversion rule storage section 4, and a character string change section 5.

The input unit 1 is a part where an operator inputs Japanese reading information in hiragana.

The kana-kanji conversion unit 2 converts the input character string into a kana-mixed character string by comparing it with the word dictionary 3.

When the word dictionary 3 does not contain a word corresponding to the input Japanese reading information, the character string changing unit 4 changes a part of the input Japanese reading information according to a specific rule.

The conversion rule storage unit 5 is a storage unit that stores the specific rule.

The operation of the embodiment configured as above will be described below with reference to FIG. 2.

Note that FIG. 2 is a flowchart showing the processing procedure at the time of kana-kanji conversion.

The operator inputs Japanese reading information in hiragana from the input unit 1. The input reading information is sent to the kana-kanji converter 2 and stored therein. For example, when the operator inputs "j to write on the floppy," this character string is sent to the kana-kanji converter 2 and stored. When instructed, the kana-kanji conversion unit 2 converts the input reading character string to a mixed character string of kanji, katakana, and kana while comparing it with the word dictionary 3 (step 31) (step 5233). In this case, for example, if the word dictionary only records the word ``floppy'' with the reading ``furoppi'', even if you first search for a word that matches the character string ``furoppi'', it will not match. It cannot be converted because the word cannot be found. Then, when referring to the conversion rules in the conversion rule storage unit 4, a rule for converting ``bi-'' to ``bii'' is found.According to this rule, the character string change unit 5 converts ``written into a floppy'' into `` The character string is changed to ``J'' (steps S2 and S4).The kana-kanji conversion unit 2 performs kana-kanji conversion again using this changed character string (step S5.
SL). Next time I found a floppy and started writing.
is also in the dictionary, the conversion result is ``Write to floppy, Neighbor Kana-Kanji conversion is successful (Step S2
, 33).

In addition to the above-mentioned examples, examples of conversion rules stored in the conversion rule storage unit 5 include "fee-", "feiyo", "tato", and "naa".

〔Effect of the invention〕

As explained above, the present invention is able to detect a katakana word that corresponds to the input Japanese pronunciation or is not found in the word dictionary.
By changing part of the input Japanese pronunciation according to specific rules and converting it to kana-kanji again, variations in katakana orthography can be absorbed and kana-kanji conversion can be performed, making it possible to perform efficient kana-kanji conversion. This has the effect of requiring less dictionary space and standardizing the notation of katakana.

Claims (1)

[Claims] (1) A means for inputting Japanese reading information in hiragana,
A word dictionary that stores katakana and kanji word information,
In the kana-kanji conversion method, which has a kana-kanji conversion means that compares the input Japanese reading information with a word dictionary and converts it into a kanji-kana mixed character string, the katakana word corresponding to the input Japanese reading is converted into a word.
