Abstract

PURPOSE:To obtain the desired candidate without necessitating the next candidate selecting operation at the time of inputting the same word by outputting preferentially a KANJI (Chinese character) and KANA (Japanese syllabary) mixed string corresponding to plural pieces of KANAs as a conversion candidate, and selecting a candidate from the conversion candidate. CONSTITUTION:A Roman letters/KANA converting part 104 refers to a Roman letters/KANA correspondence table 102 and a Roman letters/KANA learning table 103 and converts preferentially Roman letters to plural KANAs. Subsequently, a KANA KANJI converting part 106 retrieves a word dictionary 105 with respect to plural KANA character-strings converted preferentially by the Roman letters/KANA converting part 104, and executes an attached work processing as a sentence clause to the retrieved word. Next, a candidate recognized as the sentence clause is outputted to an output part 107 in order of priority, and an operator selects a desired candidate through a candidate selecting part 108. In such a way, at the time of inputting the same word, the desired candidate can be obtained without necessitating the next candidate selecting operation.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a kana-kanji conversion method and apparatus for converting a Japanese sentence specified by reading into a Japanese character string containing kanji and kana in a word processor, computer, etc.

In a conventional Japanese word processor, input modes for converting kana to kanji include a kana input mode and a romaji input mode.

The kana input mode is for inputting in hiragana and converting it to kanji, and the romaji input mode is for converting the reading input in romaji to kanji.

However, when inputting in Roman characters, there are problems specific to inputting Roman characters because Roman characters are composed of a combination of consonants and vowels. In other words, if you want to input the kanji ``n'' in romaji, you input rnJ from the keyboard, but if you input only rnJ, the following keys may not turn into ``nyo.''For example, when you want to input the kanji ``financial''. rk
If you enter inyuuJ, "Entry J" will be displayed as a conversion candidate, and "finance" as intended by the operator will not be converted.

A conventional kana-kanji conversion device devised to solve this problem and capable of manually inputting ``n'' using one rnJ key is disclosed in, for example, Japanese Patent Laid-Open No. 1-111267.

FIG. 4 is a block diagram of a conventional kana-kanji conversion device. In the figure, 401 is an input unit for inputting a character string. 4
02 is a Romaji-kana correspondence table, in which Romaji and their corresponding kana are registered in pairs. 4
04 is a Romaji-kana conversion unit that converts Romaji input from the input unit 401 into Kana using a Romaji-Kana correspondence table 402. 405 is a word dictionary in which the pronunciation, notation, and part of speech of words are registered in pairs. Reference numeral 410 is a keystroke dictionary in which Roman letters and the corresponding word notations are registered. The ephemeral kana-kanji converter 406 converts the kana character string converted into kana by the romaji-kana converter 403 into a kana-kanji mixed sentence by referring to the word dictionary 405, and also refers to the keystroke dictionary 410 if necessary. It directly converts the input Roman characters into sentences mixed with kana and kanji. 407 is an output unit that outputs the input character string and the conversion result. A candidate selection unit 408 selects a desired candidate from among the conversion candidates outputted to the output unit 407 by the kana-kanji conversion unit 406.

In reality, various other components are required in order to implement the function of instructing the operator to perform conversion, but these are not the main focus of the present invention and will therefore be omitted.

The operation of the conventional kana-kanji conversion device configured as described above will be explained below.

(1) The operator inputs a reading character string in Roman letters from the input section 401 in order to obtain a Japanese sentence.

(2) In response to the above operation, the Romaji-kana conversion unit 404 converts Romaji to Kana by referring to the Romaji-Kana correspondence table 402.

(3) Next, the kana-kanji converter 406 searches the word dictionary 405 for the kana character string converted to kana by the romaji-kana converter 403, and searches the keystroke dictionary 410 for the input romaji, Ancillary processing is performed on the searched word as a clause.

(4) Output the conversion result to the output unit 407.

(5) Finally, the operator selects a desired candidate through the candidate selection section 408.

The specific operation of the conventional kana-kanji conversion device that operates as described above will now be described. FIG. 6 is a schematic diagram showing an example of the process of inputting a Japanese document using a conventional kana-kanji conversion device.

(6) Now, to obtain the word "finance", input the Roman character string rt<1nyuuJ from the input section 401. Figure 6 (see al.

reference.

(8) Next, the kana-kanji conversion unit 406 searches the word dictionary 405 for another character string “Kinyuu” (6th
(see Figure (C)), the keystroke dictionary 410 is searched for the Roman character string "k i nyuuJ", Figure 6 (d).
As a result, the two words ``Entry-'' and ``finance'' are obtained, and the adjunct word processing as a clause is performed to obtain candidates as a clause.

(9) The conversion result “Enter” is output to the output unit 407. See Figure 6, tel.

(10) The operator selects the desired candidate "finance" using the candidate selection unit 408.

(11) Next, if you want to obtain the word "finance" again, you must repeat the operations (6) to (10) above.

Problems to be Solved by the Invention In the conventional kana-kanji conversion method and device, as explained in the above-mentioned specific example, when inputting ``n'' in rnJ, a word corresponding to another kana other than ``n'' is input. exists in the dictionary, you will need to select the next candidate even when inputting the same word. Furthermore, after “n”, “ah,”
say.

Since a dictionary is required to roughly register words that include "E, o, ya, yu7 yo", extra dictionary memory is required.

In view of the above-mentioned problems that the conventional kana-kanji conversion method and device had, the present invention has been developed to solve the problem that "n-yo" is inputted as rnJ, and "n-J" is inputted as "n-J", but there is no word corresponding to another kana other than "n-J" in the dictionary. However, by learning the selected candidates, when inputting the same word, the desired candidate can be obtained without the need to select the next candidate.

(13) Next, to obtain the word "finance" again, input the Roman character string "r k i n y u u J" from the input section 101. See Figure 3 fa).

(14) The Romaji-kana conversion unit 104 includes the Romaji-kana correspondence table 102 and the Romaji-kana learning table 103.
Refer to Convert to Kana. Currently, "rnyu nyu" is registered in the Romaji Kana Learning Dictionary 103. See Figure 3 te+. In addition, Romaji Kana correspondence table 10
As shown in FIG. 2, the Roman alphabet rnyuJ is registered in ``Nyu'' and ``Nyu'' with priority given in this order. Therefore, the romaji rkiny
For uuJ, there are two kana character strings ``Kinyuu'' and ``
``Kinyu'' is prioritized and converted in this order. See Figure 3 +f+. (15) Next, the kana-kanji conversion unit 106 searches the word dictionary 105 for the two kana character strings "Kinyuu" and "Kinyuu" (see Figure 3 (C)), and as a result, "finance", " The two words "Entry" are obtained, and the attached word processing as a clause is performed to obtain candidates as a clause.

(16) The conversion result “finance” is output to the output unit 107.

(17) The operator directly selects the desired "finance".

As mentioned above, in the kana-kanji conversion device of this embodiment,
Even if you input "n" with rnJ and there is a word corresponding to another kana other than "n" in the dictionary, by learning the selected candidate, you will not need to select the next candidate when inputting the same word. The desired candidate can be obtained immediately. In addition, the word notation "financial" for the romaji rkinyuuJ, etc.
There is no need for a dictionary to register words in which ``a, i, u, e, o, ya, yu, yo'' follows ``n'', and the dictionary memory can be reduced.

Note that in this example, the kana-kanji conversion operation is performed unconditionally for multiple kana for romaji, but
It goes without saying that unnecessary processing can be omitted by performing kana-kanji conversion only for high-priority kana, and performing kana-kanji conversion for low-priority kana only when explicitly instructed.

Effects of the Invention In the kana-kanji conversion method and device of the present invention,
Even if you input "n" with rnJ and there is a word corresponding to another kana other than "n" in the dictionary, by learning the selected candidate, you will not need to select the next candidate when inputting the same word. It is possible to obtain the desired candidate without any problem. Also, since there is no need for a dictionary to register words that come after "n" with "a, i, u, e, o, ya, yu, yo", memo Figure 1 is based on the present invention.
